What are the industrial hazards

Industrial hazards are wastewater, waste gas, waste residue

One, wastewater

1, industrial wastewater flows directly into the channels, rivers, lakes pollute surface water, if the toxicity of the larger will lead to the death of aquatic plants and animals or even extinct 2, industrial wastewater may also penetrate into the groundwater, contamination of groundwater;

2, if the neighboring residents to use the contaminated surface water or groundwater as domestic water, it will jeopardize health and kill the heavy;

3, industrial wastewater infiltrates into the soil, causing soil pollution. affecting the growth of plants and microorganisms in the soil.

4, some industrial wastewater also has an unpleasant odor, polluting the air.

5, industrial wastewater toxic and hazardous substances will be ingested and absorbed by plants and animals remain in the body, and then through the food chain to reach the human body, causing harm to the human body.

Two, exhaust gas

Industrial emissions from various types of production enterprises is an important source of air pollutants. A large number of industrial waste gas if untreated into the atmosphere after the standard, will inevitably make the quality of the atmospheric environment, to bring serious harm to human health, to the national economy has caused great losses. Industrial exhaust toxic and hazardous substances can enter the human body through the respiratory tract and skin, long-term low concentration or short-term exposure to high concentrations can cause human respiratory, blood, liver and other systems and organs temporary and permanent lesions, especially benzopyrene PAHs can make the human body directly carcinogenic to cause great importance to human beings.

Industrial waste gas including organic waste gas and inorganic waste gas. Organic waste gas mainly includes a variety of hydrocarbons, alcohols, aldehydes, acids, ketones and amines, etc.; inorganic waste gas mainly includes sulfur oxides, nitrogen oxides, carbon oxides, halogens and their compounds. China has adopted a pollutant emission control system for air pollution.

Three, waste residue

Industrial waste solid waste long-term accumulation not only occupies a large amount of land, but also causes serious pollution and harm to the water system and the atmosphere. The result of a large number of mining waste rock piles, destroying a large area of farmland and forested areas. Industrial hazardous slag long-term stockpiling, after rain and snow, soluble components with water from the surface downward infiltration. To the soil migration transformation, enrichment of harmful substances, so that the mound near the soil acidification, alkalization, hardening. Even the occurrence of heavy metal pollution. For example, generally in the soil near the non-ferrous metal smelter, lead content for the normal soil content of 10-40 times, copper content of 5-200 times, zinc content of 5-50 times. These toxic substances on the one hand through the soil into the water body, on the other hand in the soil accumulation occurs and absorbed by the crops, poisonous crops. Industrial waste and urban garbage under the action of rain, snow, into the rivers, lakes and seas, resulting in serious pollution and destruction of water bodies, if the industrial waste or garbage directly into the rivers, lakes or coastal waters will cause more pollution. The world's atomic reactor slag, nuclear explosions generated by the fallout and to the deep sea discarded radioactive waste, has made the energy of 0.74EBq (2000 × 10,000Ci) isotopes contaminated the oceans, marine biological resources have been greatly damaged. Industrial waste and garbage in the scaling process, under the action of temperature and moisture, some organic substances decompose, producing harmful gases, and some corrupt garbage waste emits a fishy odor, resulting in pollution of the air. For example: piles of gangue spontaneous combustion, the fire spreads, difficult to rescue. And release a large number of SO2 gas, pollution of the environment, in addition, take the incineration method of solid waste disposal of smoke and harmful gases discharged will also pollute the atmosphere.
