Overview
Jiangsu wastewater treatment plant serves 600,000 people in Qinhuai District, Nanjing, China. It operates under national water pollution control standards for large urban agglomerations.
The Jiangsu wastewater treatment plant is located in Qinhuai District, Nanjing, Jiangsu Province, China. It serves a population of approximately 600,000, classifying it as a large-scale municipal facility within the densely populated Yangtze River Delta region. As a major urban treatment plant in China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets stringent limits for effluent quality. Plants of this scale typically employ biological treatment processes such as activated sludge or A2O to meet Class 1A or 1B standards, depending on the receiving water body's sensitivity. The treated effluent is discharged into local waterways that ultimately drain into the Yangtze River, one of the world's largest rivers by volume. The Yangtze River basin supports diverse aquatic ecosystems and provides drinking water for millions downstream. The plant plays a critical role in protecting water quality in this ecologically and economically vital region.
Environmental context
The plant discharges into the Qinhuai River, a tributary of the Yangtze River, which flows through Nanjing and into the East China Sea. The Yangtze River basin is a major ecological corridor supporting numerous fish species, including the endangered Chinese sturgeon. Effective wastewater treatment is essential to prevent eutrophication and protect downstream aquatic habitats.
