Overview
Henan wastewater treatment plant serves Wen County in Henan Province, China, with a population equivalent of 65,000. The facility operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Wen County, Jiaozuo City, Henan Province, China, serving a population equivalent of 65,000. As a municipal facility in a densely populated region, it plays a key role in managing domestic wastewater from the local community. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), set effluent quality requirements for plants of this scale. Facilities serving populations around 65,000 typically employ secondary biological treatment processes such as activated sludge or oxidation ditch to meet these standards. The plant's treated effluent is discharged into local waterways that ultimately flow into the Yellow River basin, a major river system in northern China. The Yellow River supports extensive agricultural irrigation and provides drinking water for millions, making effective wastewater treatment critical for protecting water quality and downstream ecosystems.
Environmental context
The plant discharges into tributaries of the Yellow River, which flows through Henan Province before reaching the Bohai Sea. The Yellow River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and urban use. Proper treatment helps reduce nutrient and pollutant loads that could otherwise contribute to eutrophication and habitat degradation in downstream waters.
