1. Project Background
       In response to environmental protection policy requirements, a chemical park in Zhejiang Province has launched a sewage quality improvement project to enhance wastewater treatment capacity. The project's service scope covers industrial wastewater and domestic sewage treatment within the park, with a total designed scale of 7,500 m³/d, constructed in two phases (Phase I 5,000 m³/d, Phase II 2,500 m³/d). After completion, the effluent quality will strictly comply with the Class A standard of the "Pollutant Discharge Standard for Urban Sewage Treatment Plants" (GB18918-2002) and the relevant limits of Zhejiang Province's local standard "Discharge Standard of Major Water Pollutants for Urban Sewage Treatment Plants" (DB33/2169-2018).

3. Project significance

        The project has successfully completed installation and commissioning, and the equipment has been operating in good condition since installation. The project has built a comprehensive water quality monitoring system supporting the chemical park's wastewater treatment plant, including online monitoring of process sections, influent and outlet monitoring, and laboratory analysis equipment, covering the entire wastewater treatment process. This not only enables precise monitoring of multiple key water quality indicators but also effectively improves the park's environmental management level.
