Overview
Jiangsu wastewater treatment plant serves 760,000 people in Gulou District, Nanjing, China. It operates under national discharge standards for the Yangtze River basin.
The Jiangsu wastewater treatment plant is located in Gulou District, Nanjing, Jiangsu Province, China. It serves a population of approximately 760,000, classifying it as a large-scale municipal facility within the densely populated Yangtze River Delta region. As a major treatment plant in China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. For large agglomerations like this, advanced treatment with nutrient removal is typically required to protect sensitive receiving waters. The plant's treated effluent ultimately discharges into the Yangtze River, China's longest waterway, which flows eastward into the East China Sea near Shanghai. The Yangtze basin supports diverse aquatic ecosystems and provides drinking water for hundreds of millions of people, making effective wastewater treatment critical for water quality and public health.
Environmental context
The plant discharges into the Yangtze River, which drains into the East China Sea. The lower Yangtze basin is ecologically sensitive, supporting migratory fish species and providing critical habitat for aquatic biodiversity. Nutrient loading from urban wastewater can contribute to algal blooms and hypoxia in coastal waters, emphasizing the need for advanced treatment.
