Overview
Jiangsu wastewater treatment plant serves 400,000 people in Jiangning District, Nanjing, China. It operates under China's national wastewater standards for large urban agglomerations.
The Jiangsu wastewater treatment plant is located in Jiangning District, Nanjing, Jiangsu Province, China. It serves a population of approximately 400,000, classifying it as a large urban agglomeration under Chinese wastewater management frameworks. The plant is situated in the Yangtze River Delta region, a densely populated and industrially active area. As a large-scale facility, 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 plants serving over 100,000 people. Regulatory requirements for this population tier typically include biological treatment with nitrogen and phosphorus removal to protect receiving waters. The plant discharges into the local water system that ultimately drains into the Yangtze River, one of China's most important waterways. The Yangtze River flows eastward into the East China Sea, supporting diverse aquatic ecosystems and providing water for millions of people. The plant's operations are critical for maintaining water quality in this densely populated and economically vital region.
Environmental context
The plant's treated effluent enters local waterways that flow into the Yangtze River, which discharges into the East China Sea. The Yangtze River basin supports a wide range of aquatic life, including several endemic fish species, and is an important migratory corridor for birds. The region's high population density and industrial activity place significant pressure on water resources, making effective wastewater treatment essential for protecting downstream ecosystems and coastal waters.
