Jiangsu Wastewater Treatment Plant, Yancheng, Jiangsu, China

The Jiangsu wastewater treatment plant is located in the Xincheng subdistrict, Tinghu district, Yancheng city, Jiangsu province, China. It serves a population of approximately 35,000 people, placing it in the medium agglomeration category. As a Chinese municipal wastewater facility, the plant operates under the national discharge standards set by the Ministry of Ecology and Environment, which mandate secondary treatment for urban wastewater. For plants serving populations between 10,000 and 100,000, typical treatment includes biological processes such as activated sludge or sequencing batch reactors, with effluent standards aligned with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The plant discharges treated effluent into local waterways that ultimately drain into the Yellow Sea via the Jiangsu coastal region. The area is part of the Huai River basin, which supports diverse aquatic ecosystems and is important for regional water resource management. The plant plays a key role in protecting downstream water quality in a densely populated and industrially active region.

The treated effluent from the Jiangsu plant flows into local rivers within the Huai River basin, which drains into the Yellow Sea. This coastal region supports important fisheries and migratory bird habitats, making water quality management critical. The plant's discharge contributes to the overall health of the downstream aquatic environment, which is subject to pressures from agricultural runoff and industrial activities in the Yangtze River Delta area.
