Overview
Henan wastewater treatment plant serves Luoshan County, Henan Province, China, with a population of 82,700. It operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Luoshan County, Henan Province, China, serving a population of approximately 82,700. The facility is situated in the southern part of Henan, near the Dabie Mountains, and plays a key role in managing municipal wastewater for the region. As a medium-sized agglomeration, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which requires secondary treatment with nutrient removal for facilities of this scale. Typical plants in this region employ biological treatment processes such as activated sludge or oxidation ditch. The treated effluent is discharged into local waterways that ultimately flow into the Huai River basin, a major river system in eastern China. The Huai River drains into the Yellow Sea via the Hongze Lake and the Yangtze River. The plant's operation helps protect downstream water quality and supports aquatic ecosystems in the Huai River watershed.
Environmental context
The plant discharges into tributaries of the Huai River, which flows through Henan and Anhui provinces before reaching Hongze Lake and the Yellow Sea. The Huai River basin supports diverse aquatic life and is an important agricultural and industrial region. Proper wastewater treatment is critical to prevent eutrophication and protect downstream water quality in this densely populated watershed.
