Biological treatment: use microbial strains to dissolve renewable organic compounds in solid waste, and then achieve pollution-free or development and utilization. Biological treatment methods include aerobic treatment, anaerobic treatment and facultative anaerobic treatment. Biological treatment is usually more cost-effective politically and is widely used, but the treatment method takes a long time and the treatment efficiency is not stable enough.

Chemical treatment: Use chemical methods to destroy the harmful components in solid waste, and then achieve pollution-free, or convert it into a shape suitable for further processing and processing. The goal is to change the quality of the treatment, thereby making it less harmful. It is a commonly used pretreatment measure before hazardous waste is disposed of, and its disposal equipment is conventional chemical equipment.

Physical treatment: It is the transformation of the structure of solid waste in accordance with concentration or phase transformation of obsolete waste treatment projects, so that it can be transformed into a shape that is conducive to transportation, storage, use or processing, including compaction, crushing, screening and extraction. Solidification treatment: The solidified material is used to fix or cover the waste to reduce its damage to the key. It is a kind of treatment method that transports and treats the waste more reliably. The key is used as a hazardous waste, and the volume of the solidified body is much larger than The volume of raw waste is large.

Heat treatment: destroy and change the composition and structure of solid waste according to high temperature, and achieve the goal of volume reduction, pollution-free or development and utilization. The methods include incineration, thermal cracking, wet test oxidation and roasting

Wastes with high calorific value or high toxins are treated with incineration technology to achieve harmless treatment, and the waste heat from incineration is acquired for development and utilization, physical/chemical treatment, bathing and living of employees, etc., so as to reduce treatment costs.

The domestic waste treatment project explains that the harm of hazardous waste to the green environment is in various aspects, and the key is to pollute the water body, air and soil layer in many ways. Pollution of water bodies. Hazardous wastes flow into rivers, rivers, lakes and seas, polluting surface water; hazardous substances in hazardous wastes seep into the soil layer with leachate and pollute groundwater; if hazardous wastes are discharged into rivers, rivers, lakes and seas at any time, it will produce more strictly irreversible.

Recycling treatment: Realize the careful classification of urban domestic waste, and then select appropriate methods for disposal according to the different properties of the classified garbage, so that different types of garbage can be used, and the reduction, pollution-free and resource utilization can be achieved. .

contamination of soil layers. The smoke, dust and particulate matter of hazardous wastes flutter with the wind and fall on the surface layer of the soil layer, and then enter the soil layer to pollute the soil layer: liquid and semi-solid hazardous wastes infiltrate into the soil layer in the storage process or on the surface, and the hazardous components are mixed into the soil layer It will be serious again and cause groundwater pollution or enter the food chain according to bioconcentration.

air pollution. The harmful substances released by the evaporation and sublimation of the hazardous waste itself and the dissolution of the organic waste by the microorganisms will pollute the air at any time; the fine particles and powder in the hazardous waste diffuse into the air, which will produce air smoke pollution; in the hazardous waste In the process of material transportation, storage, use and processing, the harmful substances and soot generated will also be discharged into the air at any time or indirectly to pollute the environment.
