Overview
Henan wastewater treatment plant serves Yongcheng in Henan Province, China, with a population equivalent of 161,000. The facility operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Yongcheng, a city in Henan Province, China. It serves a population equivalent of 161,000, placing it in the medium-to-large agglomeration category under Chinese wastewater management frameworks. As a municipal facility in China, the plant is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For plants of this scale, secondary treatment with nutrient removal is typically required, especially in sensitive watersheds. The treated effluent is discharged into local water bodies that ultimately drain into the Huai River basin, a major river system in eastern China. The Huai River flows into the Yellow Sea, supporting agricultural irrigation and aquatic ecosystems along its course.
Environmental context
The plant discharges into the Huai River basin, which flows through Henan and Anhui provinces before reaching the Yellow Sea. The basin supports diverse aquatic life and is a critical water source for agriculture and industry. Downstream ecosystems depend on effective nutrient removal to prevent eutrophication in the river and coastal waters.
