Overview
Henan wastewater treatment plant serves 441,000 people in Pingdong Subdistrict, Xinyang, Henan, China. It discharges treated effluent into local waterways within the Huai River basin.
The Henan wastewater treatment plant is located in Pingdong Subdistrict, part of the Pingqiao District in Xinyang City, Henan Province, China. It serves a population of approximately 441,000, placing it in the large agglomeration category under Chinese wastewater regulations. The plant is situated along Binhe North Road, near the Shi River, a tributary of the Huai River. As a large-scale municipal facility, the plant is expected to meet national discharge standards under China's Water Pollution Prevention and Control Law. Chinese regulations require secondary or advanced treatment for plants serving over 100,000 people, with strict limits on pollutants such as COD, ammonia nitrogen, and total phosphorus. Its scale suggests it likely employs biological treatment with nutrient removal to comply with Class 1A or 1B standards. The treated effluent from the plant flows into the Shi River, which joins the Huai River downstream. The Huai River basin is a major water system in eastern China, supporting agriculture, industry, and municipal water supply. The plant plays a key role in protecting the water quality of the Huai River and its tributaries, which are ecologically important for aquatic biodiversity and downstream communities.
Environmental context
The plant discharges into the Shi River, a tributary of the Huai River, which ultimately flows into the Yellow Sea via the Hongze Lake system. The Huai River basin is a densely populated agricultural and industrial region, facing challenges from nutrient pollution and seasonal water scarcity. The plant's effluent contributes to maintaining water quality in the Shi River, which supports local fisheries and irrigation. Downstream, the Huai River provides drinking water for millions and sustains wetland ecosystems that are important for migratory birds.
