Overview
Henan wastewater treatment plant serves Wolong District, Nanyang, Henan Province, China, with a population equivalent of 913,500. It operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Wolong District, Nanyang City, Henan Province, China, along Binhe Road. It serves a population of approximately 913,500, classifying it as a large-scale municipal facility within the region. As a large agglomeration, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive water bodies. Facilities of this scale typically employ activated sludge processes with biological nutrient removal. The plant discharges treated effluent into local waterways that ultimately drain into the Yangtze River basin via the Han River system. The receiving water body supports aquatic ecosystems and provides water for agricultural and industrial use downstream. Proper treatment is critical to prevent eutrophication and protect water quality in the densely populated Henan region.
Environmental context
The plant's treated effluent flows into the Bai River, a tributary of the Han River, which joins the Yangtze River before reaching the East China Sea. The watershed supports diverse aquatic life and is an important water source for agriculture and industry in Henan Province. Nutrient loading from wastewater could contribute to algal blooms in downstream lakes and reservoirs, making advanced treatment essential for ecological balance.
