Jiangxi Wastewater Treatment Plant, Nancheng County, Jiangxi Province

The Jiangxi wastewater treatment plant is located in Jianchang, Nancheng County, Jiangxi Province, China. It serves a population of 147,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated in the inland region of Jiangxi, contributing to the local sanitation infrastructure. As a facility serving over 100,000 people, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive areas. Typical facilities of this scale employ activated sludge processes with biological nutrient removal to comply with national standards. The treated effluent from the plant likely discharges into a local river within the Poyang Lake basin, which ultimately drains into the Yangtze River and the East China Sea. The plant plays a key role in protecting downstream water quality, particularly for agricultural and ecological uses in the region.

The plant discharges into a tributary of the Fu River, part of the Poyang Lake watershed. Poyang Lake is China's largest freshwater lake and a critical wetland for migratory birds, supporting diverse aquatic life. The effluent eventually reaches the Yangtze River and the East China Sea, making nutrient control essential to prevent eutrophication in downstream waters.
