The Comprehensive Wastewater Discharge Standard of the Yellow River Basin in Shaanxi Province is formulated for the supervision and management of sewage discharge of enterprises and units in the Yellow River Basin, and its main contents include discharge standards and discharge implementation plans. In terms of emission standards, the limits of COD, BOD, ammonia nitrogen, total phosphorus and other indicators are stipulated, and there are clear requirements for them to meet the standards. Among them, the limit of chemical oxygen demand is 60 mg/L, biochemical oxygen demand is 20 mg/L, ammonia nitrogen is 5 mg/L, and total phosphorus is 0.5 mg/L. In terms of emission implementation plan, enterprises and units are required to establish perfect sewage treatment facilities and monitoring systems, and operate and manage them in strict accordance with national and local laws and regulations. In addition, Shaanxi Province has set up a special supervision and management organization to monitor and inspect the sewage discharge of enterprises and units, and will punish them if they fail to meet the standards to ensure the water quality safety of the Yellow River Basin.
What are the laws and regulations on sewage discharge in China at present? At present, the national laws and regulations on pollution discharge mainly include People's Republic of China (PRC) Water Pollution Prevention Law, People's Republic of China (PRC) Air Pollution Prevention Law and the Marine Environmental Protection Law of the People's Republic of China. In addition, all provinces, cities and counties will also formulate corresponding local laws and regulations according to local actual conditions.
It is an active measure to ensure the water quality safety of the Yellow River basin to formulate the comprehensive sewage discharge standard in Shaanxi Province. In practice, enterprises and units should abide by relevant laws and regulations, operate and manage according to emission standards and implementation plans, and maintain the health and safety of water environment.
