Overview
Henan wastewater treatment plant serves 81,200 people in Lushan County, Pingdingshan, Henan Province, China. It operates under China's national wastewater discharge standards for municipal facilities.
The Henan wastewater treatment plant is located in Lushan County, part of Pingdingshan City in Henan Province, China. It serves a population of approximately 81,200 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 Plants (GB 18918-2002), require secondary treatment as a baseline for plants of this scale. Typical facilities in this region employ biological treatment methods such as activated sludge or oxidation ditch to meet Class 1A or 1B effluent standards. The plant discharges treated wastewater into local waterways that ultimately drain into the Huai River basin, a major river system in eastern China. The Huai River flows eastward through Henan and Anhui provinces before emptying into the Yellow Sea. The receiving water bodies support agricultural irrigation and aquatic ecosystems, making proper treatment essential for protecting downstream water quality and biodiversity.
Environmental context
The plant's treated effluent enters local streams that feed into the Shahe River, a tributary of the Huai River system. The Huai River basin is a densely populated agricultural region where water quality directly impacts irrigation, fisheries, and domestic water supply. Downstream, the Huai River flows into Hongze Lake before reaching the Yellow Sea. The watershed supports diverse aquatic life and migratory fish species, requiring effective nutrient removal to prevent eutrophication in downstream lakes and coastal zones.
