Scope

This standard specifies the discharge limits of water pollutants from chemical synthesis pharmaceutical enterprises or production facilities. This standard is applicable to the management of water pollutant discharge of existing chemical synthesis pharmaceutical enterprises or production facilities. This standard applies to the environmental impact assessment, environmental protection facility design, completion environmental protection acceptance and water pollutant discharge management of chemical synthesis pharmaceutical industry construction projects. This standard is also applicable to pharmaceutical intermediate factories (such as fine chemical factories) dedicated to pharmaceutical production. This standard is also applicable to the water pollution prevention and management of veterinary drug manufacturers with similar structures to chemically synthesized drugs. 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, and the The Law of the People's Republic of China on the Prevention and Control of Environmental Pollution by Solid Waste, the Law of the People's Republic of China on the Prevention and Control of Radioactive Pollution, and the Law of the People's Republic of China on Environmental Impact Assessment 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 enterprises discharge wastewater to urban drainage systems with sewage treatment plants, the toxic pollutants total cadmium, alkylmercury, hexavalent chromium, total arsenic, total lead, total nickel, and total mercury are discharged at the monitoring positions specified in this standard. The discharge control requirements of other pollutants shall be agreed upon by the enterprise and the urban sewage treatment plant according to its sewage treatment capacity or the relevant standards shall be implemented, and shall be reported to the local environmental protection authority for record; the urban sewage treatment plant shall ensure that the discharged pollutants meet the relevant discharge standards Require. 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.
