Overview
Henan wastewater treatment plant serves 63,000 people in Qixian, Henan Province, China. The facility operates under China's national wastewater standards for urban agglomerations.
The Henan wastewater treatment plant is located in Qixian, a county-level city in Henan Province, China. It serves a population of 63,000, placing it in the medium agglomeration category. The plant is situated in the eastern part of the city, near the Qi River basin. As a Chinese municipal wastewater facility, the plant is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. For agglomerations of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, especially if discharging into sensitive water bodies. The plant's treated effluent likely discharges into the Qi River, a tributary of the Wei River, which flows into the Yellow River. The Yellow River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. Proper treatment is critical to prevent eutrophication and protect downstream ecosystems.
Environmental context
The plant discharges into the Qi River, which flows into the Wei River and ultimately the Yellow River. The Yellow River is China's second-longest river and a vital water source for northern China. The downstream environment includes agricultural areas and wetlands that depend on water quality. Effective treatment helps reduce nutrient loading and protects the river's ecological health.
