Overview
The Henan wastewater treatment plant serves the Fengshougang community in Kaifeng, Henan Province, China. It handles a population of 517,200, operating under national wastewater regulations.
The Henan wastewater treatment plant is located in the Fengshougang community, within the Gulu District of Kaifeng, Henan Province, China. It serves a population of approximately 517,200, classifying it as a large-scale municipal facility under Chinese wastewater management standards. As a large agglomeration, the plant is expected to meet secondary or advanced treatment requirements under China's national discharge standards (GB 18918-2002), which mandate pollutant removal for municipal wastewater. Typical plants of this scale employ activated sludge processes or similar biological treatment. 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 into the Yellow Sea, supporting agricultural irrigation and aquatic ecosystems. Proper treatment is critical to prevent eutrophication and protect downstream water quality.
Environmental context
The plant's treated effluent enters local tributaries of the Huai River basin, which flows through Henan and Anhui provinces before reaching the Yellow Sea. The Huai River supports diverse aquatic life and is a vital water source for agriculture and industry. Effective nutrient removal is essential to mitigate algal blooms and maintain ecological balance in this densely populated region.
