Overview
Henan wastewater treatment plant serves Taikang County in Henan Province, China, with a population equivalent of 108,000. The facility operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Yangxia Subdistrict, Taikang County, Zhoukou City, Henan Province, China. It serves a population equivalent of 108,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. For plants serving over 100,000 people, Class 1-A standards typically apply, requiring advanced treatment including biological nutrient removal and disinfection. The treated effluent is discharged into local water bodies within the Huai River basin, which ultimately drains into the East China Sea. The plant plays a critical role in protecting downstream aquatic ecosystems and supporting water quality in the densely populated Henan region.
Environmental context
The plant discharges into the Huai River basin, a major watershed in eastern China that flows through Henan, Anhui, and Jiangsu provinces before reaching the East China Sea. The basin supports extensive agricultural irrigation and provides habitat for diverse freshwater species. Downstream water bodies are ecologically sensitive due to high nutrient loads from urban and agricultural runoff, making the plant's nutrient removal performance important for preventing eutrophication.
