Jiangsu Wastewater Treatment Plant, Suyu District, Suqian, Jiangsu Province

The Jiangsu wastewater treatment plant is located in Suyu District, Suqian, within Jiangsu Province, China. It serves a population equivalent of 220,000, classifying it as a large agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1. As a facility in China, the plant operates under the national discharge standards set by the Ministry of Ecology and Environment, which mandate secondary treatment as a minimum for urban wastewater. For plants serving over 100,000 people, enhanced treatment may be required to meet stricter effluent limits, particularly in sensitive water bodies. The plant's location inland suggests it likely discharges to a freshwater system. The treated effluent from the Jiangsu plant ultimately flows into the local river network within the Huai River basin, which drains into the Yellow Sea. This basin supports extensive agricultural and urban areas, making effective wastewater treatment critical for protecting downstream water quality and aquatic ecosystems.

The plant discharges into the local river system within the Huai River basin, which flows eastward to the Yellow Sea. This watershed supports diverse aquatic life and is used for irrigation and drinking water supply downstream. Effective treatment is essential to prevent nutrient enrichment and maintain ecological balance in the receiving waters.
