Overview
Henan wastewater treatment plant serves Zhengyang County in Henan Province, China, with a population of 63,600. The facility operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Zhengyang County, under the administration of Zhumadian City, in Henan Province, China. It serves a population of approximately 63,600, classifying it as a medium-sized agglomeration under Chinese municipal wastewater management. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), require secondary treatment as a baseline for plants of this scale. Typical facilities in this region employ biological treatment methods such as activated sludge or oxidation ditch to meet national effluent standards. The treated wastewater from the plant is discharged into local waterways that ultimately drain into the Huai River basin, a major river system in eastern China. The Huai River flows into the Yellow Sea, supporting diverse aquatic ecosystems and providing water for agricultural and industrial use downstream. Proper treatment at this plant helps protect water quality in the basin.
Environmental context
The plant discharges into the Huai River basin, which flows eastward through Henan and Anhui provinces before emptying into the Yellow Sea. The Huai River is a critical water source for agriculture and industry, and its ecological health supports fish populations and migratory birds. Effective wastewater treatment is essential to prevent eutrophication and maintain water quality in this densely populated region.
