Overview
Anhui wastewater treatment plant serves 52,000 people in Jinzhai County, Lu'an City, Anhui Province, China. It operates under China's national wastewater discharge standards.
The Anhui wastewater treatment plant is located in Jinzhai County, Lu'an City, in Anhui Province, China. It serves a population of approximately 52,000, 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 for conventional pollutants and nutrients. For plants serving populations of this scale, secondary treatment with biological nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water's sensitivity. The plant's 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 eastward into Hongze Lake and then to the Yellow Sea, supporting agricultural irrigation, fisheries, and domestic water supply along its course. Proper treatment is essential to protect downstream water quality and aquatic ecosystems.
Environmental context
The plant discharges into tributaries of the Huai River, which flows through Anhui and Jiangsu provinces before reaching Hongze Lake and the Yellow Sea. The Huai River basin is a densely populated agricultural region where water quality affects irrigation, fisheries, and drinking water sources. Effective nutrient removal is critical to prevent eutrophication in downstream lakes and coastal waters.
