Henan wastewater treatment plant serves Xin County in Henan Province, China, with a population of 64,500. The plant discharges into local waterways under China's national wastewater standards.
The Henan wastewater treatment plant is located in Xin County, Henan Province, China, serving a population of approximately 64,500. It is situated in the Xinji Town area, within the broader Xinyang City region. The plant is part of China's extensive municipal wastewater infrastructure, which is regulated under national standards such as the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For a plant serving a medium-sized agglomeration of around 64,500 people, Chinese regulations typically require secondary treatment with nutrient removal in sensitive areas. It operates under the framework of China's Water Pollution Prevention and Control Law, which mandates compliance with effluent standards for receiving water bodies. The plant's treated effluent is discharged into local rivers that eventually drain into the Huai River basin, a major water system in eastern China. The Huai River flows into the Yellow Sea, supporting agricultural irrigation and aquatic ecosystems. The plant plays a key role in protecting downstream water quality and public health in the region.
Environmental context
The plant discharges into the Huai River basin, which flows through Henan and Anhui provinces before reaching the Yellow Sea. The basin supports diverse aquatic life and is used for irrigation and drinking water. Protecting this watershed from nutrient pollution is critical to prevent eutrophication and maintain ecological balance.
