Zhejiang Wastewater Treatment Plant, Fuyang District, Hangzhou

The Zhejiang wastewater treatment plant is located in Fuyang District, Hangzhou, Zhejiang Province, China. It serves a population of approximately 50,000 people, classifying it as a medium-sized municipal facility within the region's urban wastewater infrastructure. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for various pollutants. For a facility of this scale, secondary treatment with nutrient removal is typically required to meet these standards, especially in sensitive water bodies. The plant discharges treated effluent into local waterways that ultimately drain into the Fuchun River, a major tributary of the Qiantang River, which flows into Hangzhou Bay and the East China Sea. This downstream connection underscores the plant's role in protecting both freshwater and coastal ecosystems from nutrient pollution and other contaminants.

The plant's treated effluent enters the local drainage network, which flows into the Fuchun River, a key tributary of the Qiantang River. The Qiantang River discharges into Hangzhou Bay, an ecologically important estuary on the East China Sea. This watershed supports diverse aquatic life and is a critical migratory corridor for fish species. Nutrient loading from wastewater can contribute to eutrophication in the bay, making effective treatment essential for maintaining water quality and ecosystem health.
