Jiangxi Wastewater Treatment Plant, Jiujiang, Jiangxi, China

The Jiangxi wastewater treatment plant is located in Jiujiang, Jiangxi Province, China, serving a population of approximately 500,000. The facility is situated in the industrial area of Jiujiang, near the Yangtze River basin, and plays a key role in managing municipal wastewater for the region. With a designed capacity of 1.00 unit, the plant is sized to handle the wastewater from a large urban agglomeration. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations over 100,000 are typically required to achieve at least secondary treatment, with nutrient removal in sensitive areas. The plant discharges treated effluent into the local water system, which ultimately flows into the Yangtze River, one of China's most important waterways. The Yangtze River supports diverse aquatic ecosystems and provides drinking water for millions downstream. Proper treatment at this plant is critical to maintaining water quality in the river and protecting downstream communities and ecosystems.

The plant's treated effluent enters local waterways that drain into the Yangtze River, China's longest river, which flows eastward to the East China Sea. The Yangtze basin supports a rich diversity of fish and aquatic plants, and is an important migratory corridor for species such as the Chinese sturgeon. The plant's location in an industrial area means its discharge must meet strict standards to prevent pollution in this ecologically significant river system.
