Overview
Henan wastewater treatment plant serves Gushi County, Henan Province, China, with a population equivalent of 210,000. The facility operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Shahepu Town, Gushi County, Xinyang City, Henan Province, China. Serving a population equivalent of 210,000, it is a medium-to-large agglomeration facility in the region. The plant is situated inland, more than 50 km from the coast, and discharges into local water bodies. As a Chinese municipal wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). For plants serving over 100,000 people, China typically requires secondary treatment with nutrient removal in sensitive areas. Regulatory standards ensure adequate treatment for its population tier. The plant's treated effluent likely flows into the Shihe River or a tributary of the Huaihe River basin, which ultimately drains into the East China Sea. The surrounding area is predominantly agricultural, and the plant plays a key role in protecting local water quality and downstream ecosystems from nutrient pollution.
Environmental context
The plant discharges into the local watershed, part of the Huaihe River basin, which flows eastward into the East China Sea. The Huaihe River basin is ecologically significant, supporting diverse aquatic life and providing water for irrigation and domestic use. The plant's treatment helps mitigate nutrient loading and protects downstream water quality in this densely populated agricultural region.
