In September 2021, Danzhou Ecological Environment Bureau entrusted our company to conduct a normative audit on the contents of the implementation report of Danzhou's 2020 sewage discharge permit. There were 73 audited enterprises, involving brick and tile, building material manufacturing, petrochemical industry, agricultural machinery and chemical fertilizer, etc. The implementation report is an important part of the post emission permit management and an important basis for the enterprise's environmental protection self certification and legal production. In the past, in the process of early pollution source treatment and control, only controlling the emission concentration can not solve the pollution problem as a whole. Only controlling the total emission of some pollution sources and sending pollutant discharge permits can enterprises improve the regional environmental quality by realizing reasonable, standardized and efficient production and controlling the emission of pollution sources through the environmental management specified in the pollutant discharge permits issued by themselves.
