Overview
Zhejiang wastewater treatment plant serves Lishui City, Zhejiang Province, China, with a population equivalent of 140,000. The facility has a designed capacity of 1.00 unit, operating under China's national wastewater discharge standards.
The Zhejiang wastewater treatment plant is located in Qingtian County, Lishui City, Zhejiang Province, China. It serves a population equivalent of 140,000, placing it in the medium-to-large agglomeration category under Chinese wastewater management frameworks. The plant's designed capacity is 1.00, though the unit is unspecified, and it operates within the regulatory context of China's national discharge standards. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), mandate specific effluent limits based on receiving water body sensitivity. For plants serving populations over 100,000, advanced treatment is often required to meet Class 1A standards, especially in environmentally sensitive areas. The plant discharges into local water bodies that ultimately drain into the East China Sea via the Oujiang River system. The region's watershed supports diverse aquatic life and is important for downstream fisheries and coastal water quality. Effective treatment at this scale is critical to prevent eutrophication and protect the marine environment.
Environmental context
The plant's treated effluent flows into the Oujiang River basin, which drains into the East China Sea near Wenzhou. This coastal watershed supports important fisheries and migratory bird habitats. The region's subtropical climate and dense population increase the risk of nutrient loading, making advanced treatment essential for maintaining downstream water quality and marine ecosystem health.
