At present, the environmental management level of enterprises in our country is generally low, and the new Solid Waste Regulations are not fully understood and implemented, which is a major problem in hazardous waste management in our country. Hazardous waste is hazardous and has a wide range of hazards. In the process of modern industrial production, there is a large amount of hazardous waste. It is toxic, corrosive, diffusive, flammable and reactive. It can not only directly pollute the environment, but also indirectly destroy organisms in the ecosystem. At present, our country has adopted the idea of "industrial chain" in the disposal of industrial hazardous waste and established a multi-link and multi-process hazardous waste treatment system. In this paper, from a new point of view, the governance of harmful waste under the new solid waste law is selected and summarized, and the relevant provisions in the new solid waste law are analyzed. On this basis, some suggestions on the implementation of new solid waste treatment are put forward.展开更多
