Jiangsu Wastewater Treatment Plant, Liangxi District, Wuxi, Jiangsu, China

The Jiangsu wastewater treatment plant is located in Liangxi District, Wuxi, within Jiangsu Province, China. It serves a population of approximately 90,000 people, classifying it as a medium-sized agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1.00, indicating its scale of operation. As a facility in China, the plant is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on the receiving water body's sensitivity. For plants serving populations of this size, secondary treatment with nutrient removal is typically required, especially in regions like Jiangsu that are part of the Yangtze River Delta, where water quality protection is a priority. The plant discharges into local waterways that ultimately drain into the Yangtze River basin, one of China's most ecologically and economically significant river systems. The Yangtze River supports diverse aquatic life and provides water for millions of people. Proper treatment at this plant helps reduce nutrient and pollutant loads, protecting downstream ecosystems and water quality.

The plant's treated effluent flows into the local water network within the Yangtze River basin, which empties into the East China Sea. The Yangtze River Delta is a densely populated and industrialized region, making wastewater treatment critical for controlling eutrophication and safeguarding aquatic habitats. The downstream environment includes important fisheries and migratory bird routes, emphasizing the need for effective nutrient removal.
