Overview
Henan wastewater treatment plant serves Wugang City in Henan Province, China, with a population of 67,000. The facility operates under China's national wastewater standards.
The Henan wastewater treatment plant is located in Wugang City, part of Pingdingshan and Luohe prefectures in Henan Province, China. It serves a population of approximately 67,000 people, placing it in the medium-sized agglomeration category for Chinese municipal wastewater infrastructure. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), set effluent quality requirements based on receiving water sensitivity. For plants of this scale, secondary treatment with nutrient removal is typical, with higher standards applied in sensitive watersheds. The plant discharges into local water bodies that ultimately drain into the Huai River basin, a major river system in eastern China. The Huai River flows through Henan and Anhui provinces before reaching Hongze Lake and eventually the Yellow Sea. The watershed supports extensive agriculture and is ecologically important for migratory birds and aquatic biodiversity.
Environmental context
The plant's treated effluent enters local waterways within the Huai River basin, which drains through Henan and Anhui provinces into Hongze Lake and then the Yellow Sea. The Huai River watershed is ecologically sensitive due to intensive agricultural runoff and industrial activity, requiring effective nutrient removal to prevent eutrophication in downstream lakes and coastal zones.
