Overview
Zhejiang wastewater treatment plant serves Wuyi County in Zhejiang Province, China, with a population equivalent of 120,000. The facility operates under China's national wastewater discharge standards.
The Zhejiang wastewater treatment plant is located in Wuyi County, Jinhua City, Zhejiang Province, China. It serves a population of approximately 120,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated in the industrial and agricultural region of northern Zhejiang, near the Wuyi River system. As a facility serving over 100,000 people, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive water bodies. Typical plants of this scale in Zhejiang employ activated sludge processes with biological nitrogen and phosphorus removal to comply with local environmental requirements. The treated effluent likely discharges into the Wuyi River, a tributary of the Qiantang River basin, which flows into Hangzhou Bay and the East China Sea. The plant plays a critical role in protecting downstream water quality, supporting aquatic ecosystems, and maintaining the ecological health of the Qiantang River estuary, a region important for fisheries and biodiversity.
Environmental context
The plant discharges into the Wuyi River, part of the Qiantang River basin, which flows through Zhejiang Province into Hangzhou Bay and the East China Sea. The downstream environment supports diverse aquatic life and is an important migratory corridor for fish species. The Qiantang River estuary is ecologically sensitive due to its tidal dynamics and role in regional water supply and aquaculture.
