The preferential policies for hazardous waste industry are as follows:

Point 1: To prevent and control environmental pollution caused by solid waste processing and utilization, according to the Environmental Protection Law of the People's Republic of China, the Law of the People's Republic of China on the Prevention and Control of Environmental Pollution by Solid Waste, the Regulations of the State Council on Environmental Protection Management of Construction Projects and the Notice of the General Office of the Provincial Government on Strengthening the Management of Solid Waste Incineration.

point 2: for the places where the processing and utilization of solid waste are concentrated, the local government can demarcate the areas and establish solid waste processing communities according to the principle of unified planning and rational layout, and at the same time, it should set up special management institutions and personnel. Strengthen the management of processing areas.

point 3: if the designated processing and utilization units of the seventh category of imported solid waste fail to meet the requirements stipulated in article 2, or resell approval documents, goods or smuggled goods, they will all suspend accepting applications for imported waste, and the municipal environmental protection administrative department will report to the higher authorities to cancel the designated qualification, and its designated qualification will be publicly invited by the municipal environmental protection administrative department to the relevant operating enterprises in the city in September each year.

point 4: Governments at all levels should take practical and effective measures to strengthen the management of solid waste processing and utilization industry, implement hierarchical responsibility system according to the scope of their jurisdiction, and incorporate the prevention and control of solid waste pollution into the target responsibility system of government environmental protection term and the assessment of environmental protection performance of party and government leaders.

point 5: all relevant departments and their staff should act in strict accordance with the law, and must not practice favoritism, abuse their powers or neglect their duties, otherwise, the responsible persons concerned will be investigated according to law.

Various treatments in hazardous waste industry:

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

2. chemical treatment: chemical treatment is to use chemical methods to destroy harmful components in solid waste, so as to achieve harmlessness or transform it into a form 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 achieve 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 in economy and 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. Its methods include incineration, pyrolysis, wet oxidation, roasting and sintering.

waste with high calorific value or high toxicity is treated harmlessly by incineration, and the waste heat from incineration is recovered for comprehensive utilization, physical and chemical treatment, bathing and living of employees, so as to reduce the treatment cost and energy waste.

5. Solidification treatment: Solidification treatment is to fix or coat wastes with solidified substrates to reduce their harm to the environment. It is a relatively safe treatment process for transporting and disposing wastes, mainly used for hazardous wastes and radioactive wastes, and the volume of solidified bodies is much larger than that of original wastes.

6. Each treatment method has its advantages and disadvantages and applicability to different wastes. It is difficult to have a unified model because of the different components and properties of hazardous wastes. According to the characteristics of each waste, a treatment method with strong applicability can be selected
