Jiangxi Wastewater Treatment Plant, Yongxiu County, Jiangxi Province

The Jiangxi wastewater treatment plant is located in Yongxiu County, Jiujiang City, Jiangxi Province, China, within the Yunshan Economic and Technological Development Zone. It serves a population of approximately 50,000 people, classifying it as a medium-sized agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1.00, indicating its scale relative to the local community. As a facility in China, the plant operates under the national wastewater discharge standards (GB 18918-2002) and is subject to local environmental protection bureau oversight. For agglomerations of this size, secondary treatment is typically required, with potential nutrient removal in sensitive areas. Regulatory compliance is expected. The plant discharges into local water bodies that ultimately drain into the Yangtze River basin, a critical freshwater system supporting diverse aquatic life and providing water for millions. The downstream environment includes the Poyang Lake region, an ecologically significant area for migratory birds and fisheries. Proper treatment is essential to protect these downstream ecosystems from nutrient pollution and industrial contaminants.

The plant's treated wastewater flows into local waterways within the Yangtze River basin, eventually reaching Poyang Lake, China's largest freshwater lake. This lake is a vital ecological zone supporting migratory waterfowl and endemic fish species. The region's industrial activities, including nearby chemical manufacturing, necessitate robust treatment to prevent contamination of these sensitive downstream habitats.
