Overview
Henan wastewater treatment plant serves Yuanyang County, Xinxiang, Henan, China, with a population of 62,100. It operates under China's national wastewater standards for inland facilities.
The Henan wastewater treatment plant is located in Yuanyang County, Xinxiang City, Henan Province, China. It serves a population of approximately 62,100, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a Chinese treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on the receiving water's sensitivity. For inland plants like this one, Grade 1-A or 1-B standards typically apply, requiring biological treatment with nutrient removal to protect local water bodies. The plant discharges treated effluent into the local watershed, which ultimately drains into the Yellow River basin. The Yellow River is a major waterway in northern China, supporting agriculture, industry, and ecosystems. Proper treatment helps reduce nutrient and pollutant loads, safeguarding downstream water quality and aquatic habitats.
Environmental context
The plant's treated effluent enters the local drainage network within the Yellow River basin, one of China's most important river systems. The Yellow River flows through arid and semi-arid regions, making water quality management critical for agricultural irrigation and ecological health. Downstream, the river supports diverse aquatic life and provides drinking water for millions. Effective nutrient removal at this plant helps prevent eutrophication in the river and its reservoirs.
