Overview
Henan wastewater treatment plant serves Pingdingshan city in Henan province, China, with a population equivalent of 110,000. The facility operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Pingdingshan, Henan province, China, serving an estimated population of 110,000. The facility is situated in the urban area of Baofeng County, within the broader municipal infrastructure of Pingdingshan. As a plant serving a medium-sized agglomeration, it is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for facilities of this scale. The plant's discharge likely meets Class 1A or 1B standards, depending on the receiving water's sensitivity. The treated effluent 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 agricultural irrigation and aquatic ecosystems along its course. The plant plays a key role in protecting downstream water quality in this densely populated region.
Environmental context
The plant discharges into the Huai River basin, which flows through Henan and Anhui provinces before reaching the Yellow Sea. The Huai River is a vital water source for agriculture and industry, but has historically faced pollution challenges. The plant's treatment helps reduce nutrient and organic loads, supporting the ecological health of the river and its downstream wetlands.
