How to do a good job in standardized management of hazardous waste in our unit

One of the eight systems: the responsibility system for the prevention and control of environmental pollution

For waste generating units and units engaged in the collection, storage, utilization and disposal of hazardous wastes, the following four points need to be achieved:

1. Establish a hazardous waste management system. Establish the responsibility system, content management system and prevention measures to deal with hazardous waste pollution.

2, the establishment of hazardous waste management chart. There is a leading group for hazardous waste management and division of labor.

3. Establish post responsibility system. Responsibilities and responsibilities of main leaders, competent leaders, competent departments, competent leaders and supervisors of production units and production teams (employees) in hazardous waste management.

4. Establish safety operation procedures. Relevant regulations and requirements for safe operation of hazardous waste production process in enterprises.

The second of the eight systems: scoring system

1. Hazardous waste containers and packages must be marked with hazardous waste identification marks.

2, collection, storage, transportation, utilization and disposal of hazardous waste facilities, places, must set up hazardous waste identification signs.

The third of the eight systems: management planning system

1. The hazardous waste management plan includes measures to reduce the output and harmfulness of hazardous waste.

2. Hazardous waste management plan includes waste storage, utilization and disposal measures.

3, reported to the local people's governments at or above the county level environmental protection administrative department for the record.

4. When the contents of the hazardous waste management plan are significantly changed, it shall be declared in time.

The fourth of the eight systems: declaration and registration system

1. Truthfully declare the types, output, flow direction, storage and disposal of hazardous wastes to the competent administrative department of environmental protection of the local people's government at or above the county level.

(1) Truthful declaration (special declaration or integrated declaration of sewage discharge and environment)

(2) Complete contents (comprehensively and accurately declare the types, output, flow direction, storage, utilization and disposal of hazardous wastes)

(3) can provide materials to prove the authenticity and rationality of the declared data (daily records of production and processing)

2. If there are major changes in the declared items, they shall be declared in a timely manner.

The fifth of the eight systems: source classification system

1, and collect according to the characteristics of hazardous waste.

2, the implementation of the source classification system should be:

(1) Hazardous waste is separated from general waste;

(2) Industrial waste is separated from office and domestic waste;

(3) separating solid, liquid, mud and gas waste in the container;

(4) Separation of utilizable and non-utilizable wastes;

(5) separating waste with calorific value from waste without calorific value;

(6) Separation of incompatible wastes;

(7) Separation of utilization and disposal methods;

(8) to distinguish between categories, each category should also be distinguished.

The sixth of the eight systems: the delivery joint file system

1. When transferring hazardous waste funds, submit the hazardous waste transfer plan to the environmental protection department for examination and approval.

2. When transferring hazardous wastes, truthfully fill in the column of generating unit in the transfer manifest and affix the official seal in accordance with the relevant provisions of the Measures for the Administration of Hazardous Waste Transfer Manifest.

3. Transport qualifications meet the requirements: transport units, transport vehicles, drivers and escorts (the generating and transferring units are responsible for reviewing the qualifications of transport units).

4. The transfer documents are kept intact.

Seven of the Eight Systems: Business License System

1. All transferred hazardous wastes are provided or entrusted to units with hazardous waste business licenses for collection, storage, utilization and disposal.

2. Sign a contract with the hazardous waste management unit to entrust the utilization and disposal of hazardous waste.

Eight systems: emergency plan filing system

1, and formulated accident prevention measures and emergency plans.

2, to the local people's governments at or above the county level environmental protection administrative departments for the record.

3, organize emergency drills every year according to the requirements of the plan.

Extended data

deal with

Choosing the best and practical method for a waste involves many factors, such as the composition, nature, state, climatic conditions, safety standards, treatment costs, operation and maintenance of the waste. Although many methods can be successfully used to treat hazardous waste, the common treatment methods are still classified as physical treatment, chemical treatment, biological treatment, heat treatment and solidification treatment.

1. Physical treatment: Physical treatment is to change the structure of solid waste into a form convenient for transportation, storage, utilization or disposal through concentration or phase change, including compaction, crushing, sorting, concentration, adsorption and extraction.

2. Chemical treatment: Chemical treatment is to destroy harmful components in solid waste by chemical methods, so as to achieve harmlessness or transform them into forms suitable for further treatment and disposal. Its purpose is to change the chemical properties of the treated substance, thus reducing its harmfulness. This is a common pretreatment measure before the final disposal of hazardous waste, and its treatment equipment is conventional chemical equipment.

3. Biological treatment: Biological treatment is to decompose degradable organic matter in solid waste by microorganisms, so as to realize harmless or comprehensive utilization. Biological treatment methods include aerobic treatment, anaerobic treatment and facultative anaerobic treatment. Compared with chemical treatment, biological treatment is generally cheaper and more widely used, but the treatment process takes a long time and the treatment efficiency is not stable enough.

4. Heat treatment: Heat treatment is to destroy and change the composition and structure of solid waste through high temperature, and at the same time achieve the purpose of volume reduction, harmlessness or comprehensive utilization. The method includes incineration, pyrolysis, wet oxidation, roasting and sintering. Incineration technology is used to treat high calorific value or high toxic waste harmlessly, and the waste heat from incineration is recovered for comprehensive utilization, physical and chemical treatment, staff bathing and life. Thereby reducing the processing cost and energy waste.

5. Curing treatment: Curing treatment is to fix or coat waste with solidified matrix to reduce its harm to the environment. It is a relatively safe treatment process for transporting and disposing of waste, mainly used for hazardous waste and radioactive waste, and the volume of solidified body is much larger than that of original waste.

6. Each treatment method has its advantages and disadvantages and its applicability to different wastes. Because of the different components and properties of hazardous wastes, it is difficult to have a unified model. According to the characteristics of each kind of garbage, we can choose a treatment method with strong applicability.
