The various preferential policies on hazardous waste industry are as follows:

Point 1: Prevention and control of solid waste processing and utilization of industry pollution of the environment, according to the "People's Republic of China **** and the State Environmental Protection Law", "People's Republic of China **** and the State Law on Prevention and Control of Environmental Pollution by Solid Wastes", the State Council "Environmental Protection Administration of Construction Projects" and the General Office of the Provincial Government "on the enhancement of the incineration of Solid Waste Management Notice" and other laws and regulations, combined with the actual situation in the city to develop this approach.

Point 2: For the processing and utilization of solid waste is more concentrated, the local government can be based on the principle of unified planning, rational layout of the area, the establishment of solid waste processing district, at the same time, there should be a special management bodies and personnel. Processing district to strengthen the management.

Point 3: the seventh category of imported solid wastes designated for processing and utilization of units such as failing to meet the conditions set out in Article 2 or buy and sell approvals, goods, or entrainment of smuggled materials, all suspended acceptance of applications for imported wastes by the municipal environmental protection administrative department to report to the relevant departments at higher levels to cancel the qualification of the designated qualification of the designated qualification in September each year by the municipal environmental protection administrative department of the city's relevant business enterprises Public bidding.

Point 4: ? Governments at all levels should take practical and effective measures to increase the management of the solid waste processing and utilization industry, implement a hierarchical system of responsibility in accordance with the scope of the jurisdiction, and incorporate the prevention and control of solid waste pollution into the government's environmental protection tenure target responsibility system and the party and government leaders in the assessment of environmental protection performance.

Point 5: All relevant departments and their staff shall act strictly in accordance with the law, and shall not show favoritism, abuse their powers or neglect their duties; otherwise, the responsible persons will be investigated for their responsibilities according to the law.

Hazardous waste industry's various treatments:

1, physical treatment: physical treatment is through the concentration or phase changes to change the structure of solid waste to make it easy to transport, storage, utilization or disposal of the form, including compaction, crushing, sorting, thickening, adsorption, extraction and other methods.

2, chemical treatment: chemical treatment is the use of chemical methods to destroy the harmful components of solid waste, so as to achieve harmlessness, or will be transformed into a form suitable for further treatment, disposal. Its purpose is to change the chemical properties of the treated material, thereby reducing its hazardous nature. This is a common pre-treatment measure before the final disposal of hazardous waste, and its treatment equipment is conventional chemical equipment.

3, biological treatment: biological treatment is the use of microorganisms to decompose the degradable organic matter in solid waste, so as to achieve harmless or comprehensive utilization. Biological treatment methods include aerobic treatment, anaerobic treatment and part-time anaerobic treatment. Compared with chemical treatment methods, biological treatment is generally cheaper economically and commonly used, but the treatment process takes a long time and the treatment efficiency is not stable enough.

4, thermal treatment: thermal treatment is through high temperature to destroy and change the composition and structure of solid waste, while achieving the purpose of volume reduction, harmless or comprehensive utilization. Its methods include incineration, pyrolysis, wet oxidation, as well as roasting, sintering and so on.

Higher calorific value or toxicity of the waste using incineration treatment process for harmless treatment, and the recovery of incineration waste heat for comprehensive utilization and physical treatment as well as employee bathing, living, etc., to reduce the cost of treatment and waste of energy.

5, curing treatment: curing treatment is the use of curing substrate will be fixed or encapsulated waste to reduce its harm to the environment, is a safer transportation and disposal of waste treatment process, mainly for hazardous waste and radioactive waste, the volume of the curing body is much larger than the volume of the original waste.

6, a variety of treatment methods have their advantages and disadvantages and applicability to different wastes, due to the hazardous wastes contain different components, nature is difficult to have a unified model. For the characteristics of each waste can be selected for the applicability of the treatment method
