Overview
Jiangsu wastewater treatment plant serves Pukou District, Nanjing, Jiangsu, China, with a population of 600,000. It operates under China's national wastewater standards for large agglomerations.
The Jiangsu wastewater treatment plant is located in Pukou District, Nanjing, Jiangsu Province, China. It serves a population of 600,000, classifying it as a large-scale municipal facility within the Yangtze River Delta region. The plant is situated in an urban area with significant industrial and residential wastewater demands. As a large agglomeration, 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 potential nutrient removal for sensitive water bodies. Facilities of this scale typically employ activated sludge processes with advanced treatment stages to comply with local environmental regulations. The plant discharges treated effluent into the local water system, which ultimately drains into the Yangtze River, one of China's major waterways. The Yangtze River basin supports diverse aquatic ecosystems and provides drinking water for millions downstream. Proper treatment at this plant is critical to reducing nutrient and pollutant loads entering the river and its tributaries.
Environmental context
The plant's treated effluent flows into the Yangtze River basin, which drains into the East China Sea. The Yangtze is a vital ecological corridor supporting numerous fish species and migratory birds. Downstream areas include sensitive wetlands and agricultural zones that rely on good water quality. Nutrient pollution from urban wastewater can contribute to algal blooms and hypoxia in coastal waters, making advanced treatment important for this region.
