Jiangxi Wastewater Treatment Plant, Ji'an, Jiangxi Province, China

The Jiangxi wastewater treatment plant is located in Ji'an, Jiangxi Province, China, serving a population of approximately 75,000. It is situated in the Gan River basin, a major tributary of the Yangtze River, and plays a key role in managing municipal wastewater for the region. As a medium-sized agglomeration, the plant is expected to comply with China's national discharge standards under the Water Pollution Prevention and Control Law. Typical plants of this scale employ secondary biological treatment followed by disinfection to meet Class 1A or 1B standards for surface water discharge. The treated effluent ultimately flows into the Gan River, which drains into Poyang Lake, China's largest freshwater lake, and then into the Yangtze River. This watershed supports diverse aquatic life and provides water for agriculture and drinking water downstream, making effective treatment critical for ecological and public health.

The plant discharges into the Gan River, a major tributary of the Yangtze River, which flows into Poyang Lake. This lake is an ecologically sensitive area that supports migratory birds and diverse fish species. The watershed is vital for regional water supply and agriculture, requiring stringent pollution control to maintain water quality.
