Overview
Henan wastewater treatment plant serves Dancheng County in Zhoukou, Henan Province, China, with a population of 96,000. The facility operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Dancheng County, Zhoukou City, Henan Province, China. It serves a population of approximately 96,000 people, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), require secondary treatment as a baseline for urban plants. For facilities serving populations around 96,000, tertiary treatment may be mandated in sensitive watersheds to meet stricter effluent limits. The plant discharges treated effluent into local waterways that ultimately drain into the Huai River basin, a major river system in eastern China. The Huai River flows eastward into Hongze Lake and then to the Yellow Sea, supporting agricultural irrigation and aquatic ecosystems along its course.
Environmental context
The plant's treated effluent enters local tributaries of the Huai River basin, which flows through Henan and Anhui provinces before reaching Hongze Lake and the Yellow Sea. The Huai River watershed 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 receiving lakes and coastal zones.
