Overview
Henan wastewater treatment plant serves Nanyang, Henan, China, with a population of 154,000. It operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Wuxing Town, Nanyang, Henan Province, China. It serves a population of approximately 154,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. As a plant in China, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates pollutant limits based on receiving water sensitivity. For plants serving over 100,000 people, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards. The plant discharges treated effluent into local waterways that ultimately drain into the Yangtze River basin via the Han River system. The downstream environment supports diverse aquatic life and provides water for agricultural and municipal use, making proper treatment essential for ecological and public health.
Environmental context
The plant's effluent likely enters the Bai River or a tributary of the Han River, which flows into the Yangtze River and eventually the East China Sea. The watershed supports agricultural irrigation and freshwater ecosystems, including fish species important for local fisheries. Proper nutrient removal is critical to prevent eutrophication in downstream lakes and reservoirs.
