The Henan wastewater treatment plant is located in Guangshan County, Henan Province, China, serving a population of approximately 116,600. The facility is situated in the urban area of Zishui Subdistrict, near the Daguang Expressway, and plays a key role in managing municipal wastewater for the region. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations over 100,000 are typically required to achieve at least secondary treatment, with some requiring advanced treatment to meet stricter effluent limits. It is expected to comply with these regulatory requirements. The treated effluent is discharged into local water bodies that eventually drain into the Huai River basin, a major river system in eastern China. The Huai River flows eastward into the Yellow Sea, supporting agricultural irrigation and aquatic ecosystems. The plant's operation helps protect downstream water quality and public health.
Environmental context
The plant discharges into 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 critical water source for agriculture and drinking water. Downstream ecosystems include wetlands and lakes that provide habitat for migratory birds and fish species. Effective wastewater treatment is essential to prevent eutrophication and maintain water quality in this densely populated region.
