The Ministry of Ecological Environment issued five technical specifications for sewage permits, such as paint and metal casting.

In order to further improve the technical specification system of sewage permits, the Ministry of Ecological Environment recently issued the "Emission Permit Application and Issuance of Technical Specification metal foundry industry" (HJ1115-2020), "Emission Permit Application and issuance of technical specifications of coatings, inks, pigments and similar products manufacturing industry" (HJ1116-2020), "Emission permit application and issuance of technical specifications of ferroalloys, electricity" The five technical specifications of the Demanganese Industry (HJ1117-2020), "Applying for and issuing technical specifications for sewage permits and issuing technical specifications for oil storage depots, gas stations" (HJ1118-2020), and "The application and issuance of technical specifications for graphite and other non-metallic mineral products" (HJ1119-2020) comprehensively promote the reform of the sewage permit systemat present, five industry sewage permit application and issuance function will be officially launched recently, when the relevant industry sewage units can be in the national sewage license management information platform to formally declare the sewage licensecoatings, inks, pigments and similar products manufacturing industry including coating manufacturing, ink and similar products manufacturing, industrial pigment manufacturing, arts and crafts pigment manufacturing, dye manufacturing (containing machine pigment manufacturing, dyeing pigment intermediates manufacturing), sealing fillers and similar products manufacturing coatings manufacturingaccording to the industry has many product types, large size differences in sewage units, large differences in characteristic pollutants and so on, coating manufacturing and ink and similar product manufacturing focus on the control of volatile organic compounds, industrial pigment manufacturing focus on calcining unit exhaust gas emissions and wastewater discharge involving heavy metals, dye manufacturing focus on the reaction unit of wastewater and exhaust emissions, clear permitted emission concentration limits, actual Emissions accounting, compliance determination methods and self-monitoring, environmental management accounting and emission severance report and other environmental management requirements, detailed wastewater to fill in the requirements and waste water, waste gas, industrial solid waste pollution prevention and control of the operation and management requirements, after the implementation of the specification, will enhance the paint, ink, pigments and similar products manufacturing pollution prevention and control level, promote the industry sewage license is of great significancegraphite and other non-metallic mineral products manufacturing involving more types of industry mainly include: graphite, carbon products, carbon fiber, polysilicon rod monocrystalline silicon rod, asphalt mixture and other production sewage unitsGraphite and other non-metallic mineral products manufacturing pollutants mainly come from exhaust emissions, exhaust gas pollutants are mainly particulate matter, sulfur dioxide, nitrogen oxides, asphalt smoke, benzodiazepines, fluoride, hydrogen chloride and so onThis technical specification in accordance with the production process of graphite and other non-metallic mineral products manufacturing enterprises to carry out a comprehensive combing of sewage points, pollution factors, in accordance with the key management and simplified management of sewage units respectively set out the requirements of the emission gas and waste water pollutants license limits, clear waste gas, waste water, solid waste pollution prevention and control of operational management requirements, as well as enterprise self-monitoring, environmental management accounts and sewage license implementation report and other environmental management requirementsThe issuance and implementation of this technical specification will be of great significance to improve the level of pollution prevention and control in the industry and regulate the issuance of industry sewage permits
