Zhejiang Wastewater Treatment Plant, Jiaxing, Zhejiang Province, China

The Zhejiang wastewater treatment plant is located in Tianning Town, Jiashan County, Jiaxing City, Zhejiang Province, China. It serves a population of approximately 90,000 people, placing it in the medium agglomeration category for Chinese wastewater infrastructure. The facility is situated in a densely populated region of eastern China, near the Yangtze River Delta. As a Chinese municipal wastewater plant, it operates under national standards such as the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). For a plant serving 90,000 people, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The designed capacity is reported as 1.00, though the unit is unspecified, indicating the plant is sized to handle the community's wastewater load. The plant discharges treated effluent into local rivers that ultimately flow into the East China Sea via the Yangtze River estuary or nearby coastal waters. The region's dense population and industrial activity place pressure on water quality, making effective treatment crucial for protecting downstream aquatic ecosystems and drinking water sources.

The plant's treated effluent enters the local river network within the Yangtze River Delta basin, which drains into the East China Sea. This watershed supports diverse aquatic life and provides water for agriculture and industry. The delta is ecologically sensitive due to high nutrient loads from urban and agricultural runoff, requiring advanced treatment to prevent eutrophication in coastal waters.
