Overview
Henan wastewater treatment plant serves Sanmenxia Economic Development Zone in Henan, China, with a population of 271,000. The plant operates under China's national wastewater standards.
The Henan wastewater treatment plant is located in the Sanmenxia Economic Development Zone, within the Hubin District of Sanmenxia City, Henan Province, China. It serves a population of approximately 271,000 people, classifying it as a large-scale municipal facility under Chinese wastewater regulations. China's wastewater treatment standards, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), require secondary treatment as a baseline, with tertiary treatment mandated for plants discharging into sensitive water bodies. For a facility of this scale, advanced treatment processes are typically expected to meet stringent effluent limits. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Yellow River basin. The Yellow River is a major waterway in northern China, supporting agriculture, industry, and ecosystems. Proper treatment is critical to protect downstream water quality and aquatic life.
Environmental context
The plant discharges into the Yellow River basin, a vital water resource for northern China. The river supports diverse aquatic ecosystems and provides water for irrigation and drinking. Downstream, the Yellow River flows into the Bohai Sea, a semi-enclosed sea with significant ecological and economic importance. Effective wastewater treatment helps prevent eutrophication and protects the river's ecological health.
