Overview
Jiangsu wastewater treatment plant serves 160,000 people in Wujin District, Changzhou, Jiangsu Province, China. The plant has a designed capacity of 1.00 unit and discharges into local waterways.
The Jiangsu wastewater treatment plant is located in Wujin District, Changzhou, within Jiangsu Province, China. It serves a population of 160,000, placing it in the medium-to-large agglomeration category. The facility is situated in an industrial and urban area near the Yangtze River Delta. China's wastewater treatment standards are governed by the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For plants serving over 100,000 people, tertiary treatment with nutrient removal is typically required to meet Class 1-A standards, especially in sensitive water bodies. The plant's designed capacity is 1.00, and it operates under local environmental protection bureau oversight. The treated effluent likely discharges into the Grand Canal or a tributary of the Yangtze River, which flows into the East China Sea. This region is ecologically important for fisheries and migratory birds. The plant plays a key role in protecting downstream water quality in the densely populated Yangtze River Delta.
Environmental context
The plant is located in the Yangtze River Delta, a densely populated and industrialized region. Treated wastewater likely enters the Grand Canal system, which connects to the Yangtze River and ultimately the East China Sea. The downstream environment supports diverse aquatic life and is a critical migratory corridor for birds. Nutrient pollution from urban runoff and treated effluent can impact coastal ecosystems, making advanced treatment important for protecting the East China Sea.
