Overview
The Henan wastewater treatment plant serves 428,000 people in Shanyang District, Jiaozuo, Henan Province, China. It operates under China's national wastewater regulations for large agglomerations.
The Henan wastewater treatment plant is located in Shanyang District, Jiaozuo City, Henan Province, China. It serves a population of 428,000, classifying it as a large agglomeration under Chinese wastewater management standards. The plant is situated inland, approximately 50 km from the coast, and discharges into local water bodies within the Yellow River basin. As a large-scale municipal facility, the plant is expected to meet secondary or tertiary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). The regulatory framework requires advanced treatment for plants serving over 100,000 people, especially in sensitive watersheds. Typical facilities of this size employ activated sludge processes with nutrient removal. The plant's treated effluent likely flows into the Qin River or a tributary of the Yellow River, which ultimately drains into the Bohai Sea. The Yellow River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. The plant plays a key role in protecting downstream water quality in this densely populated region.
Environmental context
The plant discharges into the Yellow River basin, which flows through Henan Province and empties into the Bohai Sea. The Yellow River is a major water source for northern China, supporting irrigation, industry, and ecosystems. Downstream areas include wetlands and riverine habitats that are important for migratory birds and fish species. The plant's operations help reduce nutrient and pollutant loads, mitigating eutrophication risks in the Bohai Sea.
