Overview
The Jiangsu wastewater treatment plant serves the Jiangning District of Nanjing, China, with a population equivalent of 119,000. It operates under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in the Jiangning District of Nanjing, Jiangsu Province, China. Serving a population equivalent of 119,000, it is a medium-to-large agglomeration facility that supports the urban wastewater management needs of this rapidly developing region. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and heavy metals. The plant discharges treated effluent into local waterways that ultimately drain into the Yangtze River basin, a major ecological and economic artery. 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.
Environmental context
The plant's treated effluent flows into the Yangtze River basin, which empties into the East China Sea. The Yangtze is one of the world's most biodiverse rivers, supporting species such as the Chinese sturgeon and finless porpoise. Effective nutrient removal is essential to prevent eutrophication in downstream lakes and coastal waters, particularly in the ecologically sensitive Yangtze estuary.
