Jiangsu Wastewater Treatment Plant, Suzhou Industrial Park, China

The Jiangsu wastewater treatment plant is located in Suzhou Industrial Park, Jiangsu Province, China, serving a population of approximately 800,000. The facility is situated in the Loufeng Subdistrict, an urbanized area within the industrial park, and plays a key role in managing municipal wastewater for this densely populated region. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), set effluent limits based on receiving water sensitivity. For large agglomerations like this, advanced treatment is often required to meet Class 1A standards, especially in sensitive watersheds. The plant's designed capacity is 1.00 (likely in million cubic meters per day or similar unit), indicating a large-scale facility. The treated effluent is discharged into local waterways that ultimately flow into the Yangtze River Delta and the East China Sea. This region is ecologically significant as it supports diverse aquatic life and is a major migratory corridor for fish. The plant's operation helps protect downstream water quality in a heavily industrialized and urbanized area.

The plant discharges into the local river network within the Yangtze River Basin, which flows through the Yangtze River Delta and empties into the East China Sea. The delta is an ecologically sensitive area supporting diverse aquatic habitats and serving as a critical migratory route for fish species. Nutrient loading from urban runoff and treated effluent must be carefully managed to prevent eutrophication in downstream coastal waters.
