Overview
Jiangxi wastewater treatment plant serves 53,200 people in Yongfeng County, Ji'an, Jiangxi Province, China. It operates under China's national wastewater standards for medium-sized agglomerations.
The Jiangxi wastewater treatment plant is located in Yongfeng County, within the city of Ji'an, Jiangxi Province, China. It serves a population of approximately 53,200 people, classifying it as a medium-sized agglomeration under Chinese wastewater management frameworks. The plant is situated inland, away from coastal areas, and its operations are part of the broader municipal infrastructure for the region. As a facility serving over 50,000 residents, the plant is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. Plants of this scale typically employ biological treatment methods such as activated sludge or sequencing batch reactors to meet regulatory requirements. The treated effluent from the plant is discharged into local water bodies within the Gan River basin, which ultimately flows into Poyang Lake, China's largest freshwater lake, and then into the Yangtze River. This downstream connection highlights the plant's role in protecting water quality in a major river-lake ecosystem that supports diverse aquatic life and provides water for agriculture and fisheries.
Environmental context
The plant discharges into the Gan River basin, which drains into Poyang Lake, a critical wetland and floodplain system in Jiangxi Province. Poyang Lake is a major migratory stopover for waterbirds along the East Asian-Australasian Flyway and supports a rich diversity of fish and aquatic plants. The lake's ecological health depends on nutrient and pollutant loads from upstream sources, making the treatment plant's performance important for maintaining water quality in this sensitive downstream environment.
