Henan wastewater treatment plant is located in 鲇鱼山街道, 商城县, within the city of 信阳市, 河南省, China. The facility serves a population of 93,400, classifying it as a medium-sized agglomeration under Chinese wastewater management frameworks. As a plant in China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. For agglomerations of this scale, secondary treatment with nutrient removal is typically required to meet Class 1A or 1B standards, especially if discharging into sensitive water bodies. The plant's treated effluent likely discharges into a local river within the Huai River basin, which ultimately flows into the East China Sea. The downstream environment supports agricultural irrigation and aquatic ecosystems, making proper treatment essential for water quality and public health.
Environmental context
The plant discharges into a tributary of the Huai River system, which flows eastward through Henan and Anhui provinces before reaching the East China Sea. The Huai River basin is a major agricultural region, and its waters support diverse aquatic life and provide irrigation for crops. Effective wastewater treatment is critical to prevent eutrophication and protect downstream water quality.
