Jiangxi Wastewater Treatment Plant, Le'an County, Jiangxi Province, China

The Jiangxi wastewater treatment plant is located in Le'an County, Jiangxi Province, China, serving a population of approximately 74,700. As a municipal facility in a county-level city, it plays a key role in managing domestic wastewater from the local urban area. The plant operates under China's national wastewater discharge standards (GB 18918-2002), which mandate secondary treatment for urban wastewater treatment plants. For a facility serving a population of this scale, typical treatment includes biological processes such as activated sludge or oxidation ditch, with nutrient removal increasingly required in sensitive watersheds. The treated effluent is discharged into local water bodies that ultimately drain into the Poyang Lake basin, the largest freshwater lake in China, which connects to the Yangtze River. The plant's operation helps protect downstream aquatic ecosystems and supports water quality in the region.

The plant's receiving water body is part of the Poyang Lake basin, which drains into the Yangtze River. Poyang Lake is a critical wetland ecosystem supporting diverse aquatic life and migratory birds. The plant's discharge contributes to maintaining water quality in this ecologically sensitive watershed, where nutrient loading from urban areas is a key concern.
