Overview
Henan wastewater treatment plant serves Lushi County in Henan Province, China, with a population of 38,000. The facility operates under China's national wastewater standards.
The Henan wastewater treatment plant is located in Lushi County, Dongming Town, within Sanmenxia City, Henan Province, China. It serves a population of approximately 38,000 people, placing it in the medium agglomeration category for Chinese municipal wastewater infrastructure. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), set effluent limits based on receiving water sensitivity. For plants of this scale, secondary treatment with nutrient removal is typically required to meet Class 1A or 1B standards, especially when discharging into sensitive water bodies. The plant's treated effluent likely discharges into a local river within the Yellow River basin, as Lushi County is situated in the upper reaches of the Yellow River watershed. The downstream environment supports agricultural irrigation and aquatic ecosystems, making proper treatment essential for protecting water quality and biodiversity in the region.
Environmental context
The plant is located in the Yellow River basin, one of China's most important water systems, which ultimately flows into the Bohai Sea. The receiving water body is likely a tributary of the Yellow River, supporting local agriculture and freshwater habitats. Downstream ecosystems depend on adequate treatment to prevent eutrophication and maintain water quality for irrigation and domestic use.
