Overview
Jiangsu wastewater treatment plant serves Qingjiangpu District, Huai'an, Jiangsu, China, with a population equivalent of 104,600. The facility has a designed capacity of 1.00 unit and operates under China's national wastewater regulations.
The Jiangsu wastewater treatment plant is located in Qingjiangpu District, Huai'an, within the Jiangsu province of China. It serves a population equivalent of approximately 104,600, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The facility is situated in the Xin'gang area of Liushuwan Subdistrict, part of the Huai'an Economic and Technological Development Zone. As a plant of this scale in China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates pollutant removal levels based on receiving water sensitivity. Plants serving over 100,000 people typically employ biological treatment with nutrient removal to meet Class 1-A or 1-B standards. The designed capacity is recorded as 1.00, though the unit is unspecified. The treated effluent from this plant is discharged into local waterways that ultimately drain into the Huai River basin, a major river system in eastern China. The Huai River flows eastward into Hongze Lake and then to the Yellow Sea. This watershed supports extensive agricultural irrigation and provides habitat for diverse aquatic species. Proper treatment is critical to prevent eutrophication and protect downstream water quality in this densely populated region.
Environmental context
The plant discharges into the Huai River basin, which flows through Jiangsu province into Hongze Lake, one of China's largest freshwater lakes, before reaching the Yellow Sea. The watershed supports intensive agriculture and fisheries, making nutrient control essential to prevent algal blooms and maintain water quality for downstream communities and ecosystems.
