Overview
Henan wastewater treatment plant serves the Chanhe Hui District of Luoyang, China, with a population equivalent of 669,000. The facility operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in the Chanhe Hui District of Luoyang, Henan Province, China. It serves a population equivalent of 669,000, placing it in the large agglomeration category. The plant is situated near the Erguang Expressway in the Taiping community, within the Tawan subdistrict. As a major municipal facility in China, the plant is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets stringent limits for pollutants like COD, BOD, ammonia nitrogen, and phosphorus. For large plants serving over 500,000 people, advanced treatment with nutrient removal is typically required to meet Class 1A standards, especially in sensitive watersheds. The plant's treated effluent is discharged into the local water system, which ultimately drains into the Luo River, a tributary of the Yellow River. The Yellow River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. Proper treatment at this plant helps protect downstream water quality and the health of the Yellow River ecosystem.
Environmental context
The plant discharges into the Luo River, a major tributary of the Yellow River, which flows through Henan Province before reaching the Bohai Sea. The Yellow River basin is a critical water resource for northern China, supporting agriculture, industry, and urban water supply. The downstream environment includes sensitive wetlands and aquatic habitats that depend on adequate water quality. Effective wastewater treatment at this plant helps reduce nutrient and pollutant loads, mitigating eutrophication risks and protecting biodiversity in the river and coastal zone.
