Overview
Henan wastewater treatment plant serves Yancheng District, Luohe City, Henan Province, China, with a population equivalent of 68,400. It operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Yancheng District, Luohe City, Henan Province, China. It serves a population equivalent of 68,400, placing it in the medium agglomeration category for Chinese municipal wastewater infrastructure. The plant is situated inland, approximately 50 km from the coast, and discharges into local water bodies. As a municipal facility in China, the plant is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. For plants serving populations between 10,000 and 100,000, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the sensitivity of the receiving water body. The plant's treated effluent likely enters the local river system, which drains into the Huai River basin, ultimately reaching the East China Sea. The Huai River basin is a major agricultural and industrial region, and proper wastewater treatment is critical to prevent eutrophication and protect downstream aquatic ecosystems. The plant's inland location reduces direct marine impact but still plays a key role in regional water quality management.
Environmental context
The plant discharges into the local river network within the Huai River basin, which flows eastward into the East China Sea. The Huai River is one of China's major rivers, supporting extensive agriculture and fisheries. Downstream ecosystems include floodplain wetlands and lakes that provide habitat for migratory birds and aquatic species. Nutrient loading from untreated or inadequately treated wastewater can contribute to algal blooms and hypoxia in downstream waters, making effective treatment essential for ecological health.
