Jiangsu Wastewater Treatment Plant, Wuzhong District, Suzhou | China

The Jiangsu wastewater treatment plant is located in Wuzhong District, Suzhou, within Jiangsu Province, China. It serves a population equivalent of approximately 97,000, placing it in the medium-to-large agglomeration category. The plant's designed capacity is 1.00 (units unspecified), reflecting its role in managing municipal wastewater from the surrounding urban area. As a facility in China, the plant operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and heavy metals. For plants serving populations of this scale, secondary treatment with nutrient removal is typically required, especially in sensitive water bodies. The plant discharges into the local water system within the Yangtze River Delta region, which ultimately drains into the East China Sea. The receiving water body supports diverse aquatic life and is an important ecological corridor. The plant's performance is critical for protecting downstream water quality and maintaining the ecological health of the delta's intricate network of rivers and lakes.

The plant is situated in the Yangtze River Delta, a densely populated and economically vital region. Its treated effluent enters local waterways that flow into the Yangtze River estuary and eventually the East China Sea. The delta's aquatic ecosystems support fisheries and migratory bird populations, making effective wastewater treatment essential for preventing eutrophication and maintaining biodiversity.
