Overview
Henan wastewater treatment plant serves Xinzheng City in Henan Province, China, with a population of 106,500. The facility operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Xinhua Road Subdistrict, Xinzheng City, Zhengzhou, Henan Province, China. It serves a population of approximately 106,500, classifying it as a medium-to-large urban wastewater treatment facility within the region. As a Chinese municipal wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for various pollutants. For plants serving over 100,000 people, Chinese regulations typically require advanced treatment with nutrient removal to meet Class 1A or 1B standards, especially in sensitive watersheds. The plant's treated effluent is discharged into local waterways that ultimately drain into the Huai River basin, a major river system in eastern China. The Huai River flows eastward through Henan and Anhui provinces before emptying into the Yellow Sea. The plant plays a critical role in protecting downstream water quality and aquatic ecosystems in this densely populated agricultural region.
Environmental context
The Henan plant discharges into the Huai River basin, which flows through Henan and Anhui provinces to the Yellow Sea. The Huai River watershed supports diverse aquatic life and is an important water source for agriculture and industry. Downstream ecosystems include wetlands and lakes that provide habitat for migratory birds and fish species. Protecting water quality in this basin is critical due to high population density and intensive land use.
