Overview
Henan wastewater treatment plant serves Xinzhuang, Qixian County, Kaifeng, Henan, China. It treats wastewater for approximately 63,000 people, supporting local water quality in the region.
The Henan wastewater treatment plant is located in Xinzhuang, a town in Qixian County, Kaifeng City, Henan Province, China. The facility serves a population of approximately 63,000, making it a medium-sized agglomeration under Chinese wastewater management standards. It plays a key role in managing municipal wastewater for this part of Henan Province. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), set effluent quality requirements based on the receiving water body's sensitivity. For plants serving populations of this scale, secondary treatment with nutrient removal is typically required, especially if the discharge enters a sensitive water body. It operates under the national regulatory framework. The treated effluent 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 the Yellow Sea, supporting agricultural irrigation, fisheries, and aquatic ecosystems. Protecting this watershed is critical for downstream water quality and biodiversity in Henan and beyond.
Environmental context
The plant discharges into local watercourses that are part of the Huai River basin. The Huai River flows through Henan, Anhui, and Jiangsu provinces before emptying into the Yellow Sea. This watershed supports extensive agriculture and provides habitat for diverse aquatic species. Maintaining proper treatment levels is essential to prevent nutrient pollution and protect downstream ecosystems.
