Jiangsu Wastewater Treatment Plant, Dafeng District, Yancheng, Jiangsu, China

The Jiangsu wastewater treatment plant is located in Dafeng District, Yancheng, Jiangsu Province, China. It serves a population of approximately 120,000 people, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations of this scale are typically required to achieve secondary treatment or higher, with nutrient removal in sensitive areas. The plant likely operates under permits issued by the Jiangsu Provincial Department of Ecology and Environment, which enforces effluent limits based on the receiving water body's classification. The treated effluent from this plant is discharged into local waterways that ultimately drain into the Yellow Sea via the coastal river systems of Jiangsu. The region's flat terrain and dense population make proper wastewater treatment critical for protecting downstream aquatic ecosystems and coastal water quality.

The plant discharges into the river network of the Jiangsu coastal plain, which flows into the Yellow Sea. This area supports important fisheries and migratory bird habitats along the East Asian-Australasian Flyway. Effective nutrient removal is essential to prevent eutrophication in the coastal zone, which is ecologically sensitive due to its role as a spawning and nursery ground for marine species.
