Overview
Henan wastewater treatment plant serves Tongbai County, Nanyang, Henan, China, with a population of 58,200. It operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Qinghuai Street, Tongbai County, Nanyang, Henan Province, China. It serves a population of approximately 58,200, placing it in the medium agglomeration category for Chinese municipal wastewater infrastructure. The plant is situated inland, away from coastal zones, and its operations are governed by China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For a plant of this scale, Chinese regulations typically require secondary treatment with nutrient removal in sensitive watersheds. It is expected to meet Class 1-A or 1-B standards depending on the receiving water body's sensitivity. Compliance is monitored by local environmental protection bureaus under the Ministry of Ecology and Environment. The plant discharges treated effluent into local waterways that ultimately drain into the Huai River basin, a major river system in eastern China. The Huai River flows eastward into Hongze Lake and eventually reaches the Yellow Sea. The watershed supports agricultural irrigation, fisheries, and urban water supply, making effective wastewater treatment critical for downstream water quality and ecosystem health.
Environmental context
The plant's treated effluent enters local tributaries of the Huai River basin, which flows through Henan and Anhui provinces before reaching Hongze Lake and the Yellow Sea. The Huai River watershed is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. Downstream areas include wetlands and lakes that are important for migratory birds and fish spawning. Effective treatment helps reduce nutrient loading and protect these freshwater ecosystems from eutrophication.
