The Henan wastewater treatment plant is located in Fangcheng County, Nanyang City, Henan Province, China, along Zhangqian Avenue near Bali Bridge. It serves an estimated population of 77,000 people, making it a medium-sized municipal facility in the region. As a Chinese wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. For a plant serving a population of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The plant discharges treated effluent into local waterways that ultimately drain into the Yangtze River basin via the Han River system. This watershed supports agricultural irrigation, fisheries, and downstream ecosystems. Proper treatment is essential to protect water quality in the densely populated and agriculturally active Henan region.
Environmental context
The plant's treated effluent flows into local streams that are part of the Han River watershed, a major tributary of the Yangtze River. This river system supports diverse aquatic life and provides water for irrigation and domestic use in Henan Province. Downstream, the Yangtze River estuary is an ecologically sensitive area that sustains fisheries and migratory bird populations. Nutrient and pollutant control at this plant helps prevent eutrophication and protects downstream water quality.
