必备仪器清单，2026国家生态环境标准入河入海排污口监测新规

Core Viewpoint - The newly released national ecological environment standard "Technical Guidelines for Supervision and Management of Pollutant Discharge Outlets into Rivers and Seas" will officially implement on March 1, 2026, focusing on the standardized construction of pollutant discharge outlets into the sea [1][2]. Group 1: Standard Requirements - The standard outlines requirements for the construction of pollutant discharge outlets, including the outlet mouth, discharge channel, monitoring sampling points, signage, monitoring systems, inspection wells, and archives [5][7]. - All pollutant discharge outlets must implement standardized construction for the outlet mouth, discharge channel, monitoring sampling points, signage, and archives, with key management outlets required to monitor flow [7][13]. Group 2: Specific Construction Guidelines - The outlet mouth should be located seaward of the legal coastline, and the discharge channel should ideally be buried underground, adhering to relevant construction regulations [9][10]. - The construction must ensure safety and prevent leakage, water level backflow, and seawater intrusion [11]. Group 3: Monitoring and Sampling - Monitoring sampling points should generally be set at the outlet mouth; if not feasible, they can be placed as close as possible to the mouth, avoiding tidal influences [14]. - In cases where multiple discharge units share an outlet, the monitoring point should be set after the wastewater has mixed [16]. Group 4: Signage and Public Supervision - Signage must be placed in a visible location for public supervision, including essential information such as the outlet name, regulatory department, and a QR code for easy access to information [18]. - The signage should be made of durable materials resistant to environmental conditions and should be maintained regularly to ensure clarity and visibility [18]. Group 5: Monitoring Systems - Flow measurement can utilize various methods, including velocity meters and weirs, with specific installation and usage regulations [19]. - Video monitoring systems must comply with relevant regulations, ensuring safety and security during operation [20]. - Water quality online monitoring systems should also adhere to established guidelines for installation and operation [21]. Group 6: Documentation and Management - Archives must include basic information, regulatory materials, and monitoring data, with daily management following relevant regulations [22]. - The use of a national information management platform for backup and management of archives is encouraged [22].
