The Ministry of ecology and environment issued five technical specifications for pollution discharge permits, such as coating and metal casting

In order to further improve the technical specification system of emission permits, the Ministry of ecology and environment recently issued five technical specifications to comprehensively promote the reform of emission permits.

In order to further improve the technical specification system of emission permits, recently, the Ministry of ecological environment issued the emission permit application and issuance technical specification metal casting industry (hj1115-2020), emission permit application and issuance technical specification paint, ink, pigment and similar product manufacturing industry (hj1116-2020), emission permit application and issuance technical specification ferroalloy and electrolytic manganese Industry (hj1117-2020), technical specifications for application and issuance of pollutant discharge permit oil storage and gas station (hj1118-2020), technical specifications for application and issuance of pollutant discharge permit graphite and other non-metallic mineral products manufacturing (hj1119-2020), and comprehensively promote the reform of pollutant discharge permit system.

At present, the application and issuance functions of emission permits for five industries will be officially launched in the near future. At that time, relevant industry emission units can formally apply for emission permits in the national emission permit management information platform.

Coating, ink, pigment and similar products manufacturing industry includes coating manufacturing, ink and similar products manufacturing, industrial pigment manufacturing, arts and crafts pigment manufacturing, dye manufacturing (including organic pigment manufacturing, dye intermediate manufacturing), sealing filler and similar products manufacturing coating manufacturing.

According to the characteristics of the industry, such as many types of products, large differences in the scale of pollutant discharge units, and large differences in characteristic pollutants, coating manufacturing and ink and similar products manufacturing focus on the control of volatile organic compounds, industrial pigment manufacturing focuses on the waste gas discharge of calcination unit and the waste water discharge link involving heavy metals, and dye manufacturing focuses on the waste water and waste gas discharge of reaction unit, It defines the environmental management requirements such as the allowable emission concentration limit, actual emission accounting, compliance determination method, self-monitoring, environmental management account and emission permit implementation report, and details the reporting requirements of waste water destination and the operation management requirements of waste water, waste gas and industrial solid waste pollution prevention and control. After standardized implementation, it will improve the coating, ink, pigment and similar The level of pollution prevention and control in product manufacturing industry and the promotion of the issuance of emission permits are of great significance.

There are many industries involved in the manufacturing of graphite and other non-metallic mineral products, mainly including: graphite, carbon products, carbon fiber, polycrystalline silicon rod, monocrystalline silicon rod, asphalt mixture and other production units. The pollutants produced by graphite and other non-metallic mineral products mainly come from exhaust gas emissions, which mainly include particulate matter, sulfur dioxide, nitrogen oxide, asphalt smoke, benzopyrene, fluoride, hydrogen chloride, etc.

This technical specification comprehensively combs the production and discharge stains and pollution factors of graphite and other non-metallic mineral products manufacturing enterprises according to the production process. According to the key management and simplified management of pollutant discharge units, it respectively stipulates the permit limit requirements for waste gas and waste water pollutants, defines the operation and management requirements for waste gas, waste water, solid waste pollution prevention and control, as well as the self-monitoring and environmental protection of enterprises Environmental management requirements such as environmental management standing book and discharge permit implementation report. The release and implementation of this technical specification will be of great significance for improving the level of pollution prevention and control in the industry and standardizing the issuance of emission permits in the industry.
