According to Zhao Wenquan, director of the Technical Committee of the China Rubber Association, the main products involved in the calculation of the sewerage coefficient of the rubber products industry are tires for vehicles, aircraft and construction machinery, tire manufacturing, tire retreading, recycled rubber manufacturing, and rubber additives. product. In this regard, the China Rubber Association established a task force and an expert group to select a representative 36 enterprise organizations to conduct site surveys. The pollutants include waste water, waste gas, solid waste, and other eight major pollutants. Twenty-five identical combinations (products, raw materials, production technology and production scale), accounting for 206 original pollutant generation coefficients, 165 original pollutant discharge coefficients, 108 individual pollutant generation coefficients, and 86 individual pollutant discharge coefficients, and finally completed 5 There are a professional emission-discharge coefficient manual, a production-discharge coefficient calculation technical report, and a production-discharge coefficient calculation report and a corresponding database. The completed pollutant discharge coefficient can cover the combination of five professional product processes, raw material use processes, and treatment technologies and equipment related to the finished product process. The accounting production and emission factor can cover 100% of the corresponding products.
According to the acceptance opinion of the expert group, the actual measurement and accounting work reflected the actual status of the production and discharge of pollutants in the rubber products industry, and met the needs of accounting work for the generation and emission of pollutants in the corresponding industries in the first national pollution source survey.
The issue of “Calculation of the Sewage Coefficients of the Rubber Products Industry†undertaken by the China Rubber Industry Association recently passed the acceptance of the China Academy of Environmental Sciences. Experts believe that the rubber yield from the rubber products industry provided by this project fills the gap in the basic data of the industry's environmental management, and has technical support for industrial environmental planning, environmental statistics, environmental standards, and environmental research.
