Overview
Henan wastewater treatment plant serves Wuzhi County in Henan Province, China, with a population of 74,300. It operates under China's national wastewater regulations.
The Henan wastewater treatment plant is located in Wuzhi County, Jiaozuo City, Henan Province, China. It serves a population of approximately 74,300 people, placing it in the medium agglomeration category. The plant is situated in the inland region of northern Henan, an area characterized by agricultural and industrial activity. Under China's national wastewater discharge standards (GB 18918-2002), treatment plants serving populations of this scale are typically required to meet Class 1-A or Class 1-B effluent standards, which mandate biological treatment with nutrient removal. Facilities of this size in China generally employ activated sludge or similar secondary treatment technologies to comply with regulatory requirements. The plant discharges treated effluent into local waterways that ultimately drain into the Yellow River basin, one of China's major river systems. The Yellow River flows eastward through Henan and into the Bohai Sea. The plant plays a critical role in protecting downstream water quality and supporting the ecological health of the Yellow River watershed, which is vital for agriculture, industry, and drinking water supply in the region.
Environmental context
The plant's treated effluent enters local tributaries that feed into the Yellow River, which flows through Henan Province and discharges into the Bohai Sea. The Yellow River basin supports diverse aquatic life and provides water for millions of people. The plant helps reduce nutrient and pollutant loads, protecting downstream ecosystems and water quality in this agriculturally intensive region.
