Jiangsu Wastewater Treatment Plant, Sucheng District, Suqian

The Jiangsu wastewater treatment plant is located on Yunhe Di Road in the Sucheng Economic Development Zone (South Area), Xiangli Subdistrict, Sucheng District, Suqian City, Jiangsu Province, China. It serves a population of approximately 8,000 residents, classifying it as a small-scale municipal facility under Chinese wastewater management standards. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), require secondary treatment as a baseline for urban plants. For facilities serving smaller communities like this one, treatment processes typically involve biological treatment methods such as activated sludge or biofilm reactors to meet local discharge limits. The plant's treated effluent is discharged into the local water network, which ultimately drains into the Huai River basin. The Huai River is a major waterway in eastern China, flowing into the Yellow Sea. Protecting this river system is critical for downstream water quality, aquatic biodiversity, and regional water resource sustainability.

The plant discharges into the local canal and river system within the Huai River basin, which flows eastward through Jiangsu Province and empties into the Yellow Sea. The Huai River supports diverse aquatic life and is an important water source for agriculture and industry. Downstream ecosystems rely on effective nutrient removal to prevent eutrophication and maintain ecological balance.
