Overview
Zhejiang wastewater treatment plant serves 30,000 people in Jiashan County, Jiaxing City, Zhejiang Province, China. It has a designed capacity of 1.00 (units unspecified) and discharges into local waterways.
The Zhejiang wastewater treatment plant is located in Ganyao Town, Jiashan County, within Jiaxing City, Zhejiang Province, China. It serves a population of approximately 30,000, classifying it as a small to medium agglomeration under Chinese wastewater management standards. As a facility in China, the plant operates under national wastewater discharge standards, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). For plants serving populations around 30,000, 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. It is expected to comply with these regulations. The plant discharges into local rivers that eventually flow into the Yangtze River Delta region, which drains into the East China Sea. This area is ecologically sensitive due to its role in supporting fisheries, agriculture, and biodiversity. Proper treatment is crucial to prevent eutrophication and protect downstream aquatic ecosystems.
Environmental context
The plant's treated effluent likely enters local waterways in the Yangtze River Delta, a densely populated and agriculturally intensive region. These waters flow into the East China Sea, supporting important coastal fisheries and migratory bird habitats. Nutrient pollution from wastewater can contribute to algal blooms and hypoxic zones, making effective treatment essential for maintaining water quality and ecosystem health.
