Overview
Henan wastewater treatment plant serves Lingbao City in Henan Province, China, with a population of 131,000. It operates under China's national wastewater standards for urban agglomerations.
The Henan wastewater treatment plant is located in the Chenguan Town area of Lingbao City, within the Sanmenxia region of Henan Province, China. Serving a population of approximately 131,000, the facility is part of the municipal infrastructure for this inland city in the Yellow River basin. As a plant serving a medium-to-large agglomeration, it is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive areas. Typical plants of this scale employ activated sludge processes with biological nutrient removal. The plant discharges treated effluent into local waterways that ultimately flow into the Yellow River, a major river system in northern China. The Yellow River basin supports diverse aquatic life and provides water for agriculture and industry downstream. Proper treatment is critical to protect water quality in this ecologically and economically important watershed.
Environmental context
The plant's treated effluent enters local tributaries of the Yellow River, which flows through Henan Province and eventually into the Bohai Sea. The Yellow River basin is a vital water source for northern China, supporting irrigation, industry, and ecosystems. Downstream areas include sensitive wetlands and habitats for migratory birds, making effective wastewater treatment essential for maintaining water quality and ecological balance.
