Overview
Henan wastewater treatment plant serves Hebi City, Henan Province, China, with a population equivalent of 146,200. The plant discharges treated effluent into local waterways within the Hai River basin.
The Henan wastewater treatment plant is located in Hebi City, Henan Province, China, serving a population of approximately 146,200. It is situated in the Qihe District, an urban area within the larger Hebi municipality. The plant is part of China's extensive municipal wastewater infrastructure, which is regulated under national standards for water pollution control. As a medium-to-large agglomeration, the plant is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This standard mandates treatment levels appropriate for the receiving water's environmental sensitivity. Typical facilities of this scale employ biological treatment processes such as activated sludge. The treated effluent is discharged into local rivers that flow into the Hai River system, which ultimately drains into the Bohai Sea. The Hai River basin is a critical water resource for northern China, supporting agriculture, industry, and urban water supply. The plant plays a key role in protecting downstream water quality and aquatic ecosystems in this densely populated region.
Environmental context
The plant discharges into the Hai River basin, which flows through Henan and Hebei provinces before reaching the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea with significant ecological importance, supporting fisheries and migratory bird populations. The Hai River system faces challenges from industrial and agricultural runoff, making effective wastewater treatment essential for maintaining water quality and ecosystem health in the downstream environment.
