Scope

This standard specifies the discharge limits of water and air pollutants for the characteristic production processes and devices of synthetic leather and artificial leather industrial enterprises. This standard is applicable to the discharge management of water and air pollutants in the characteristic production processes and devices of existing synthetic leather and artificial leather industrial enterprises. This standard applies to the environmental impact assessment of synthetic leather and artificial leather industrial construction projects, the design of environmental protection facilities, the completion of environmental protection acceptance and the management of water and air pollutant discharge after production. This standard applies to the discharge of pollutants permitted by law. The site selection of newly established pollution sources and the management of existing pollution sources in special protection areas shall be in accordance with the Law of the People's Republic of China on the Prevention and Control of Air Pollution, the Law of the People's Republic of China on the Prevention and Control of Water Pollution, the Law of the People's Republic of China on Marine Environmental Protection, the Solid State The Law of the People's Republic of China on the Prevention and Control of Environmental Pollution by Waste, the Law of the People's Republic of China on the Prevention and Control of Radioactive Pollution, the Law of the People's Republic of China on Environmental Impact Assessment, and other laws, regulations, and rules are implemented. The water pollutant discharge control requirements stipulated in this standard are applicable to the discharge behavior of enterprises to environmental water bodies. When an enterprise discharges wastewater into the urban drainage system with a sewage treatment plant, the pollutant discharge control requirements shall be negotiated between the enterprise and the urban sewage treatment plant or implement relevant standards based on its sewage treatment capacity, and reported to the local environmental protection authority for record; urban sewage The treatment plant should ensure that the discharged pollutants meet the requirements of the relevant discharge standards. When a construction project intends to discharge wastewater into the urban drainage system with a sewage treatment plant, the construction unit and the urban sewage treatment plant shall implement the provisions of the preceding paragraph.
