Overview
Henan wastewater treatment plant serves 47,300 people in Yucheng County, Shangqiu City, Henan Province, China. The facility operates under China's national wastewater discharge standards for municipal treatment plants.
The Henan wastewater treatment plant is located in Yucheng County, part of Shangqiu City in Henan Province, China. It serves a population of approximately 47,300, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. 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 around 47,300, secondary treatment with nutrient removal is typically expected to meet Class 1-A or 1-B standards, depending on local environmental needs. The plant's treated effluent likely discharges into a local watercourse within the Huai River basin, which flows eastward into the Yellow Sea. The Huai River system supports extensive agricultural irrigation and provides drinking water for millions, making effective wastewater treatment critical for protecting downstream water quality and aquatic ecosystems.
Environmental context
The plant is situated inland in the Huai River basin, which drains into the Yellow Sea via the Huai River and its tributaries. This watershed supports intensive agriculture and urban water supply across Henan and Anhui provinces. Effective nutrient removal is essential to prevent eutrophication in downstream lakes and coastal waters, as the region faces seasonal algal blooms and water quality challenges from agricultural runoff and municipal discharges.
