Henan Wastewater Treatment Plant, Shanyang District, Jiaozuo, Henan Province

Henan wastewater treatment plant is located in Shanyang District, Jiaozuo City, Henan Province, China. It serves a population of approximately 73,000 people, classifying it as a medium-sized agglomeration under Chinese municipal wastewater management. The plant operates within China's regulatory framework, which mandates secondary treatment for urban wastewater under the national discharge standards (GB 18918-2002). For plants serving populations between 10,000 and 100,000, secondary treatment with nutrient removal is typically required to protect receiving waters. The treated effluent is discharged into local waterways that eventually drain into the Yellow River basin, a major river system in northern China. The plant plays a key role in protecting downstream aquatic ecosystems and supporting water quality in the region.

The plant discharges into local tributaries of the Yellow River basin, which flows through Henan Province and ultimately into the Bohai Sea. The Yellow River is a critical water resource for agriculture and urban supply in northern China, and its downstream reaches support diverse aquatic life. The plant's operations help reduce nutrient and pollutant loads, contributing to the ecological health of this important river system.
