How to control air pollution

Question 1: How to control the pollution sources of air pollution is the fundamental measure to prevent and control the harm of air pollution, and there are many control methods. Here are the main methods.

(1). The industrial layout is reasonable, so as to facilitate the diffusion of pollutants and the mutual utilization of waste gas between factories and reduce the emission of waste gas.

(2) Implement regional central heating, replace scattered low chimneys with high-efficiency boilers, and replace scattered low chimneys with high-efficiency boilers. This is a powerful measure to prevent and control urban air pollution.

(3) Change the fuel composition. For example, develop urban industrial and civil gas and liquefied petroleum gas, and adopt low-sulfur fuel and new energy sources (solar energy, wind energy, geothermal energy, etc.). ). Coal mining should be carried out to remove most sulfur (mainly pyrite sulfur) from coal.

(4) Reduce automobile exhaust emissions. Mainly to change the engine combustion design, improve the combustion quality of oil products and strengthen traffic management.

(5) The toxic gases emitted by industrial devices should be controlled from the aspects of process transformation and recycling.

(6). Chimney dust removal. The control technology of sulfur dioxide in flue gas can be divided into two categories: dry method (using solid powder or particles as absorbent) and wet method (using liquid as absorbent).

2. Change the fuel structure, develop new energy sources, gradually promote the use of natural gas, coal gas and liquefied petroleum gas, choose low-sulfur fuels, desulfurize heavy oil and coal, and develop and utilize new energy sources such as solar energy, hydrogen fuel and geothermal energy.

3. Reform production technology and control waste gas. The control of industrial air pollutants mainly focuses on dust removal and control of sulfur dioxide and nitrogen oxide emissions.

4. Setting up large-scale electric heating plants and heating stations for regional central heating, especially setting up thermal power plants and heating stations in suburbs, is a very effective measure to eliminate smoke and dust and provide heating in winter in northern cities.

5. The higher the chimney, the more conducive to the diffusion and dilution of flue gas. Generally, when the chimney height exceeds 100m, the effect is very obvious, and it is not economical to increase the cost greatly if it is too high. It should be pointed out that this is a way to reduce local ground pollution at the expense of expanding the pollution range.

6. Control the exhaust emission time

7, transportation waste gas treatment

Question 2: How to prevent and control air pollution? 1) air pollution source

Air pollution sources can be divided into natural and man-made two categories. Natural pollution sources are formed due to natural causes (such as volcanic eruptions, forest fires, etc.). ), and man-made pollution sources are formed because people are engaged in production and life activities. Among man-made pollution sources, it can be divided into fixed (such as chimneys and industrial exhaust pipes) and mobile (such as cars, trains, planes and ships). Due to the prevalence and frequency of man-made pollution sources, people pay more attention to them than natural pollution sources. The main air pollution sources are:

(1) industrial enterprises are the main source of air pollution and one of the key points of air hygiene protection. With the rapid development of industry, the types and quantities of air pollutants are increasing. Due to the different nature, scale, technological process, raw materials and product types of industrial enterprises, the degree of air pollution is also different.

(2) Living stoves and heating boilers in residential areas, with the concentration of population, a large number of civil living stoves and heating boilers also need to consume a lot of coal, especially in winter heating time, which often makes the polluted areas filled with smoke, which is also an air pollution source that cannot be ignored.

(3) Transportation In recent decades, due to the development of transportation, more and more cars are driving in the city, and passenger and cargo transportation such as trains, ships and planes is frequent, which has added new air pollution sources to the city. Of great significance is the exhaust gas emitted by cars. The characteristic of automobile air pollution is that the pollutants discharged are close to people's breathing zone and can be directly inhaled by people. The exhaust gas from automobile internal combustion engines mainly contains carbon monoxide, nitrogen oxides, hydrocarbons and lead compounds.

(B) the harm and impact of air pollution

The harm and influence of air pollution on human beings and their living environment has been gradually recognized by people, which can be summarized as follows:

① Harm to human health. There are three ways for human body to suffer, that is, inhaling polluted air, skin contact with polluted air, and eating food containing atmospheric pollutants, which will not only cause respiratory and lung diseases, but also harm cardiovascular system and liver, and even seriously endanger people's lives.

② Harm to living things. Animals get sick or die from inhaling polluted air or eating food containing pollutants. Air pollutants will reduce the disease resistance of plants, affect their growth and development, and cause leaf spot or wither and die.

③ Damage to articles. Such as textiles and clothing, leather, metal products, building materials, cultural works of art, etc. , causing chemical damage and pollution damage.

④ Causing acid rain, which has adverse effects on agriculture, forestry and freshwater aquaculture.

⑤ Destroy the upper ozone layer and form an ozone hole, which is harmful to the living environment of human beings and organisms.

⑥ It has an impact on the global climate. For example, the increase of greenhouse gases such as carbon dioxide will lead to the warming of the earth's atmosphere and the increase of global weather disasters. For example, the increase of aerosol particles such as smoke and dust will increase atmospheric turbidity, weaken solar radiation, affect the long-wave radiation of the earth, and may lead to abnormal weather and climate.

How to prevent and control air pollution and reduce its harm and influence has become a major and urgent research topic.

(3) Prevention and control of air pollution

The prevention and control of air pollution is a huge systematic project, which requires the joint efforts of individuals, collectives, countries and even countries all over the world. The following measures can be considered:

(1) Reduce pollutant emissions. Pollution-free energy (such as solar energy, wind energy, hydropower generation), energy structure reform, low-pollution energy (such as natural gas), fuel pretreatment (such as desulfurization before burning coal), and improved combustion technology can all reduce pollutant emissions. In addition, before pollutants enter the atmosphere, some pollutants in waste gas can be eliminated by dust removal and smoke elimination technology, condensation technology, liquid absorption technology and recycling technology, so as to reduce the amount of pollutants entering the atmosphere.

② Control emissions and make full use of the self-purification ability of the atmosphere. Different meteorological conditions have different atmospheric capacity of pollutants, and the same pollutant discharge will cause different pollutant concentrations. For areas and time periods with strong wind, good ventilation, strong turbulence and strong convection, the atmospheric diffusion and dilution ability is strong, and it can accept more areas and time periods where the temperature of factories and mines is reversed. If the atmospheric diffusion and dilution ability is weak, it can't accept more pollutants, otherwise it will cause serious air pollution. Therefore, effective emission control should be carried out in different regions and different time periods.

(3) Site selection, chimney design, urban and industrial zone planning, etc. It should be reasonable, and large emitters should not be over-concentrated, so as not to cause repeated pollution ... >>

Question 3: How to control air pollution According to the national standard "Code for Indoor Environmental Pollution Control of Civil Building Engineering", five pollutants, namely formaldehyde, benzene, ammonia, radon and TVOC, are listed for control.

The main source of formaldehyde

1, decoration materials and new combination furniture;

2.UF foam is used as thermal insulation material for building heat and cold protection;

3, paint, chemical fiber carpets, cosmetics and other products with formaldehyde as preservative;

4. Smoking indoors.

The main source of benzene

1, indoor paint decoration;

2. Wood coatings;

The main source of TVOC

1. Wood-based panels, foam insulation materials and plastic plates in building materials;

2. Paints, coatings, adhesives, wallpapers and carpets in interior decoration materials;

3. Cosmetics, perfumes, fresheners, detergents, etc. Commonly used in life;

4. Office supplies mainly refer to ink, photocopiers, typewriters, etc.

5. Household fuel and smoking, human excreta and outdoor industrial waste gas, automobile exhaust and photochemical pollution.

Harm of benzene

Benzene is a colorless gas with special fragrance, which has been identified as a strong carcinogen by the World Health Organization. Benzene is the main reason for the increase of childhood leukemia patients in recent years. According to the survey data, 90% of children with leukemia in cities have done interior decoration within one year.

Inhalation of high concentration benzene in a short period of time will have the anesthetic effect of the central nervous system, ranging from dizziness, headache, nausea, vomiting, chest tightness and fatigue, to coma or even death due to respiratory and circulatory failure! If exposed to a certain concentration of benzene for a long time, it will cause chronic poisoning, such as headache, insomnia, listlessness, memory loss and other neurasthenia symptoms.

Harm of formaldehyde

Formaldehyde is a colorless and strongly irritating gas, which has been identified as carcinogenic and teratogenic by the World Health Organization. Formaldehyde pollution can cause eye tears, hyperemia and inflammation of cornea and conjunctiva, skin allergy, nasopharyngeal discomfort, cough, acute and chronic bronchitis and other respiratory diseases, and can also cause nausea, vomiting and gastrointestinal dysfunction! Severe cases can also cause persistent headache, pneumonia, pulmonary edema, loss of appetite, and even death.

Long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, eye diseases, irregular menstruation and disorder in women, pregnancy syndrome, neonatal malformation and mental depression. In addition, it can also promote the physical decline of newborns and cause heart disease in children. According to the investigation of American medical department, formaldehyde pollution is the main reason for the increase of asthma in children aged 3-5.

Harm of ammonia

Ammonia is a colorless gas with strong smell, which is lighter than air (specific gravity 0.5). Ammonia is an alkaline substance, which has corrosive and corrosive effects on the skin tissue in contact with it. It can absorb moisture in skin tissue, denature tissue protein, saponify tissue fat and destroy cell membrane structure. When the concentration is too high, in addition to corrosion, it can also cause cardiac arrest and respiratory arrest through the reverse action of trigeminal nerve endings. Ammonia is usually inhaled into alveoli in the form of gas. After ammonia is inhaled into the lungs, it can easily enter the blood through alveoli, combine with hemoglobin, and destroy the oxygen transmission function. The solubility of ammonia is very high, so it mainly corrodes the upper respiratory tract of animals or human bodies, weakening the resistance of human bodies to diseases. A small amount of ammonia is neutralized by carbon dioxide, and the remaining small amount of ammonia is absorbed into the blood, which can be excreted with sweat, urine or respiratory tract. Some people will have symptoms such as skin pigmentation or finger ulcers when they are exposed to ammonia for a long time; After inhaling a large amount of ammonia in a short time, there may be symptoms such as tears, sore throat, hoarseness, cough, bloodshot sputum, chest tightness, dyspnea, dizziness, headache, nausea, vomiting and fatigue. In severe cases, pulmonary edema, adult respiratory distress syndrome and respiratory symptoms may occur. Therefore, alkaline substances do deeper and more serious damage to tissues than acidic substances.

The harm of TVOC

Volatile organic compounds (TVOC) mostly refer to compounds with boiling point of 50-250. According to their different chemical structures, TVOC can be further divided into eight categories. Alkanes, aromatics, olefins, halogenated hydrocarbons, aldehydes, ketones and others. 50-300 kinds of volatile organic compounds can be seen in non-industrial indoor environment. They all appear in trace and measured levels, and each compound rarely exceeds the level of 50 mg/m3. TVOC can cause the imbalance of immune level and affect the center. & gt

Question 4: How to prevent air pollution? The pollutants in the air will have adverse effects on human beings. Controlling air pollution has become one of the main measures to save energy and reduce emissions. This paper discusses the basic control methods and prevention measures of major air pollutants in China at present, including measures to reduce air pollutants, air pollution control technology, strengthening supervision and law enforcement, etc. Air pollutants; Prevention; manage

The atmosphere is an important part of human living environment, and the quality of atmospheric environment is closely related to human living. Some common air pollutants will cause direct or indirect harm to human body. There are generally two forms of atmospheric pollutants, namely particulate pollutants and gaseous pollutants. Particulate pollutants are mainly soot, and gaseous pollutants include sulfur dioxide, nitrogen oxides, carbon monoxide and hydrogen-containing gases. Air pollutants can diffuse in the atmosphere and have the characteristics of wide pollution range, strong regionality and integrity. Therefore, the degree of air pollution is related to the natural conditions, energy composition, industrial structure and layout, traffic conditions and population density in this area. The fundamental way to prevent and control atmospheric pollutants is to start with the pollution sources, and ensure the quality of the atmospheric environment by reducing the emission of pollutants and promoting the diffusion and dilution of pollutants. At the same time, starting from the overall environment of the region, fully considering the environmental characteristics of the region, comprehensively and systematically analyzing various factors that can affect the air quality, making full use of the self-purification ability of the environment itself, and adopting the best prevention and control methods, the purpose of controlling the air environmental quality and reducing air pollution has been achieved [1]. The comprehensive prevention and control of air pollutants should mainly start from the following aspects. 1 Take various measures to reduce the generation of pollutants.

1. 1 Overall planning and rational layout

The comprehensive prevention and control of air pollution must start with coordinating the relationship between regional economic development and environmental protection, comprehensively investigate and study the types, quantities and spatial distribution of various pollutants discharged by various pollution sources in this area, and formulate the best scheme for controlling pollutants on this basis [2]. For example, the industrial production area should be located in the downwind of the dominant wind direction in the city; There should be a certain distance between the factory and the urban living area, and urban green belts should be built to reduce the harm of air pollution. Strictly examine and approve new construction, renovation and expansion projects, and order enterprises without pollution control facilities or with imperfect pollution control facilities to stop work and make rectification within a time limit. Enterprises with serious pollution, waste of resources and hopeless governance should resolutely take measures such as closing and stopping. 1.2 Improve the energy structure and increase the effective utilization rate of energy.

China is a big coal-burning country, and a large number of pollutants such as sulfur dioxide, nitrogen oxides, carbon monoxide and suspended particles are released during coal burning. China's coal-based energy structure will not change fundamentally in the short term, so the production and use of briquette and low-sulfur coal preparation should be given priority to reduce the emission of smoke and sulfur dioxide. In addition, to fundamentally solve the air pollution problem, we must start with improving the energy structure. For example, the use of natural gas and secondary energy such as coking gas and liquefied petroleum gas will increase the utilization of clean energy such as solar energy, wind energy, geothermal energy, tidal energy, biological energy and nuclear fusion energy.

1.3 district heating and central heating are implemented.

Domestic coal-fired stoves and various small boilers for heating and boiling water distributed in urban areas emit a lot of sulfur dioxide and smoke, which is an important reason for the deterioration of urban atmospheric environment. Taking measures of urban central heating and district heating can solve this problem well. Advantages of district heating and central heating: First, it can improve the utilization rate of boiler equipment and reduce fuel consumption; Second, it can make full use of heat energy and improve the heat utilization rate; Third, it is convenient to use high-efficiency dust removal equipment, which greatly reduces dust emission. The fourth is to reduce the transportation of fuel, thus reducing the use of transportation equipment and indirectly reducing the emission of atmospheric pollutants. 1.4 Planting trees and greening the environment

Afforestation is an economical and effective measure to prevent and control air pollution. Plants have the functions of absorbing all kinds of toxic and harmful gases and purifying the air, and are natural filters of the air. After being washed away by rain, dusty leaves can restore the function of absorbing and blocking dust, so that the air can be purified. Photosynthesis of plants can release oxygen and absorb carbon dioxide. The general broad-leaved forest with 1 hm2 can consume about 1 t of carbon dioxide and release 750 kg of oxygen every day, which plays a good role in air conditioning [3]. 2 adopt various professional technologies to control pollutant discharge. 2. 1 Treatment of granular pollutants

Most of the smoke in the atmosphere (mainly composed of particulate pollutants) ...

Question 5: How to control air pollution? Pollution source is the fundamental measure to prevent and control the harm of air pollution, and there are many control methods. Here are the main methods.

It should be pointed out that this is a way to reduce local ground pollution at the expense of expanding the pollution range.

6. Control the exhaust emission time

7, transportation waste gas treatment

Question 6: What are the air pollution control methods 1? Strengthen legislative supervision, strictly enforce laws and regulations, and standardize emission standards.

2. Develop new energy sources, use new technologies and reduce the use of traditional energy sources.

3. Strengthen publicity, enhance citizens' awareness of environmental protection and consciously protect the environment.

4. Set up reasonable points in the city to monitor air quality, and make the monitoring indicators public.

5. Rational planning of cities, rational layout of industrial areas, commercial areas and living areas.

6. Planting trees and greening cities

Question 7: How to prevent air pollution?

1, improve the awareness of indoor air pollution prevention and control, develop scientific living habits, and open the window regularly for ventilation every day, even in winter.

Don't overheat the cooking oil when cooking. When cooking, turn on the hood and open the window for ventilation to reduce the indoor air pollution caused by cooking with oil.

Try not to smoke indoors to reduce the indoor air pollution caused by smoke.

4. In interior decoration, we should carefully choose building and decoration materials to avoid excessive decoration.

5. When purchasing furniture, you should choose solid wood furniture, and try not to choose furniture made of MDF and fiberboard to reduce the release of formaldehyde in the adhesive.

6. Don't rush into the newly renovated room. You should open the window and ventilate for a while before you check in. Because the release of formaldehyde in buildings, decorative materials and furniture is a slow process, it is still necessary to open the window every day after check-in to ensure enough fresh air in the room.

7. Try not to keep pets indoors. Bedding, blankets and carpets should always be dried in the sun to avoid the breeding of dust mites.

Planting some green plants indoors can play a certain role in purifying the air.

9. When the indoor air quality is not good, please ask a qualified testing unit for testing.

Question 8: How to prevent and control air pollution? Pollutants in the air will have adverse effects on human beings.

Question 9: How to deal with the serious air pollution in cities? The comprehensive prevention and control of air pollution involves a wide range and the influencing factors are complex. Generally speaking, waste gas treatment can be carried out in the following four aspects:

(1) district central heating.

Coal-fired stoves scattered in thousands of households and dense short chimneys in cities are the main pollution sources of smoke and dust. Developing regional central heating, establishing large thermal power plants and heating stations to replace the stoves of thousands of households are effective measures to eliminate smoke and dust. This also has the following advantages: 1 high chimney emission; 2. Reduce the transportation of fuel; 3. Improve the utilization rate of heat energy; 4. It is more convenient to use high-efficiency dust collector.

(2) Planting trees and selecting forests to green the environment.

Afforestation is an economical and effective measure to control waste gas. Plants have the function of absorbing all kinds of toxic and harmful gases and purifying the air. Plants are natural filters of air. The surface of leaves is rough and fluffy, and some

The leaves of tree species also secrete mucus, which can absorb a lot of floating dust. After being washed away by rain, the dusty leaves can restore the functions of adsorption and blocking dust, so that the air can be purified. Dense jungle can reduce the wind speed and make the airflow carry it.

Large particles of dust fall.

(3) Improve the energy structure and increase the effective utilization rate of energy.

China's coal-based energy structure will not change fundamentally in the short term. Therefore, at present, we should first promote the production and use of briquette and coal washing to reduce the emission of smoke and sulfur dioxide. At present, the energy structure is dominated by coal, accounting for 73% of the total commercial energy consumption. In the process of burning coal, a large number of pollutants such as sulfur dioxide (SO2), nitrogen oxides (nitrogen oxides), carbon monoxide (CO) and suspended particles will be released. Therefore, to fundamentally solve the problem of air pollution, we must first improve the energy structure, such as using natural gas and secondary energy sources, such as gas, liquefied petroleum gas and electricity. We should also pay attention to the use of so-called clean energy such as solar energy, wind energy and geothermal energy.

China's average energy utilization rate is only 30%, and there is great potential to improve energy utilization rate. There are more than 200,000 boilers in China, which consume more than 200 million tons of coal every year. Therefore, reasonable selection of boilers, upgrading and upgrading of inefficient boilers and improving their thermal efficiency can effectively reduce air pollution caused by coal burning.

(4) Overall planning and rational layout.

Waste gas control must proceed from coordinating the relationship between regional economic development and environmental protection, and conduct a comprehensive investigation and study on the types, quantities and temporal and spatial distribution of various pollutants discharged by various pollution sources in this area, and on this basis, formulate the best scheme for pollution control.

The industrial production area should be located in the downwind of the dominant wind direction in the city. The factory should keep a certain distance from the urban living area and plant trees to reduce pollution hazards. Enterprises with heavy pollution, waste of resources and hopeless waste gas treatment should be closed, stopped, merged, transferred and moved.

If you have more suggestions on air pollution control, please write to tell E Fengji.

Question 10: How to solve the air pollution control in China? By transferring pollution sources and industries, Britain has transferred many heavily polluted industries and industries to Africa.

In addition, vigorously develop new technologies for air pollution control, develop clean energy and implement green public transportation. This is the only way.
