Jiangsu Wastewater Treatment Plant, Jurong City, Jiangsu Province

The Jiangsu wastewater treatment plant is located in Baohua Town, Jurong City, Zhenjiang, Jiangsu Province, China. It serves a population of approximately 250,000, classifying it as a large-scale municipal facility within the region. As a plant of this scale in China, it is expected to comply with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive areas. Typical facilities serving this population size employ advanced biological treatment to meet Class 1A or 1B effluent standards. The plant discharges treated wastewater into local water bodies that ultimately drain into the Yangtze River basin, a major ecological and economic corridor. The Yangtze River supports diverse aquatic life and provides drinking water for millions, making effective wastewater treatment critical for downstream water quality and ecosystem health.

The plant is located in the Yangtze River basin, one of China's most important watersheds. Treated effluent likely enters local streams that flow into the Yangtze River, which empties into the East China Sea. The Yangtze supports a rich biodiversity, including endangered species like the Chinese sturgeon, and provides water for agriculture, industry, and domestic use. Protecting this river from nutrient pollution and contaminants is essential for maintaining ecological balance and public health.
