This standard specifies the discharge limits of water pollutants for pulp and paper enterprises or production facilities. This standard is applicable to the management of water pollutant discharge of existing pulp and paper enterprises or production facilities. This standard applies to the environmental impact assessment of pulp and paper industry construction projects, the design of environmental protection facilities, the completion of environmental protection acceptance and the management of water pollutant discharge after commissioning. 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 Prevention and Control of Air Pollution", "Law of the People's Republic of China on Prevention and Control of Water Pollution", "Law of the People's Republic of China on Marine Environmental Protection" and "The People's Republic of China 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, 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 enterprises discharge wastewater into urban drainage systems with sewage treatment plants, toxic pollutants such as adsorbable organic halogens (AOX) and dioxins shall implement corresponding discharge limits at the monitoring positions specified in this standard; the discharge control requirements for other pollutants shall be determined by Enterprises and urban sewage treatment plants agree or implement relevant standards based on their sewage treatment capacity, and report to the local environmental protection authority for record; urban sewage treatment plants should ensure that the pollutants discharged meet the requirements of 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.
