Overview
Henan wastewater treatment plant serves Weihui City in Henan Province, China, with a population equivalent of 128,700. The facility operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Weihui City, Xinxiang, Henan Province, China. It serves a population equivalent of approximately 128,700, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management frameworks. The plant is situated in an inland region, away from coastal areas, and its operations are integral to local water quality management. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), set effluent limits based on receiving water body sensitivity. For plants of this scale, secondary treatment with nutrient removal is typically required, especially if discharging into sensitive water bodies. The regulatory framework ensures compliance with national standards. The plant discharges treated effluent into local waterways that ultimately flow into the Hai River basin, which drains into the Bohai Sea. The Hai River system is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. Proper treatment at this plant helps reduce nutrient and pollutant loads, protecting downstream ecosystems and water quality.
Environmental context
The plant's treated effluent enters local tributaries of the Hai River system, which flows through Henan and Hebei provinces before reaching the Bohai Sea. The Hai River basin is a heavily utilized water resource, supporting agriculture, industry, and urban populations. Downstream ecosystems include wetlands and estuaries that provide critical habitat for migratory birds and aquatic species. Effective wastewater treatment is essential to prevent eutrophication and maintain ecological balance in this densely populated region.
