Overview
Jiangsu wastewater treatment plant serves 52,000 people in Jiangning District, Nanjing, China. It operates under Chinese national wastewater standards for urban agglomerations.
The Jiangsu wastewater treatment plant is located in Jiangning District, Nanjing, Jiangsu Province, China. It serves a population of 52,000, classifying it as a medium-sized urban agglomeration under Chinese wastewater management frameworks. The facility is situated in the densely populated Yangtze River Delta region, an area with significant industrial and residential water use. As a plant serving over 50,000 people, it is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). Chinese regulations require advanced treatment (Class 1A) for plants discharging into sensitive water bodies, which is common in the Yangtze River basin. Its scale implies a robust infrastructure to handle municipal and possibly industrial inflows. The plant's treated effluent likely discharges into local waterways that flow into the Yangtze River, one of the world's major river systems. The Yangtze River Delta is ecologically significant, supporting diverse aquatic life and providing water for millions. Proper treatment is critical to prevent eutrophication and protect downstream ecosystems, including the East China Sea.
Environmental context
The plant is located in the Yangtze River Delta, where treated wastewater likely enters tributaries of the Yangtze River before reaching the East China Sea. The Yangtze basin supports a wide range of aquatic species, including the endangered Yangtze finless porpoise. Nutrient and pollutant loads from urban and industrial sources pose risks to water quality, making effective treatment essential for maintaining ecological balance in this densely populated and economically vital region.
Frequently asked questions
The plant is located in Jiangning District, Nanjing, Jiangsu Province, China, in the Yangtze River Delta region.
The plant serves approximately 52,000 people, classifying it as a medium-sized urban agglomeration.
The plant's treated effluent likely discharges into local waterways that flow into the Yangtze River, helping protect the river's water quality and downstream ecosystems.
The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment for plants of this scale, with stricter Class 1A standards for sensitive areas.
Plants of this size typically employ secondary biological treatment processes such as activated sludge, often with nutrient removal to meet Class 1A standards, especially in ecologically sensitive regions like the Yangtze River basin.
