Overview
Henan wastewater treatment plant serves Luoning County, Luoyang, Henan, China, with a population of 59,000. It operates under China's national wastewater standards for inland facilities.
The Henan wastewater treatment plant is located in Fengyi Town, Luoning County, Luoyang City, Henan Province, China. It serves a population of approximately 59,000 people, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a Chinese wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on receiving water body sensitivity. For inland plants like this one, Grade 1-A or 1-B standards typically apply, requiring biological treatment with nutrient removal to protect downstream water quality. The plant discharges treated effluent into local waterways that ultimately drain into the Yellow River basin, a major river system in northern China. The Yellow River supports extensive agricultural irrigation and provides drinking water for millions, making effective wastewater treatment critical for preventing eutrophication and protecting aquatic ecosystems in the region.
Environmental context
The plant's treated effluent flows into tributaries of the Yellow River, which traverses Henan Province before reaching the Bohai Sea. The Yellow River basin is ecologically sensitive due to high sediment loads and periodic water scarcity, and nutrient pollution from upstream sources can exacerbate algal blooms in downstream reservoirs and coastal zones. Effective treatment at this facility helps maintain water quality for agricultural and domestic use along the river's course.
