Jiangxi Wastewater Treatment Plant, Qingshanhu District, Nanchang, China

The Jiangxi wastewater treatment plant is located in Qingshanhu District, Nanchang, Jiangxi Province, China. It serves a population of approximately 750,000 people, classifying it as a large-scale municipal facility within the region. The plant's designed capacity is 1. As a large agglomeration in China, the plant is expected to meet national discharge standards under the Environmental Protection Law and the Water Pollution Prevention and Control Law. These regulations mandate secondary treatment as a minimum, with advanced treatment required for sensitive water bodies. Its scale suggests compliance with these standards to protect local water quality. The plant discharges into the local water system, which ultimately drains into Poyang Lake, China's largest freshwater lake, and then into the Yangtze River. This downstream connection highlights the plant's role in safeguarding the ecological health of Poyang Lake, a critical wetland habitat supporting diverse aquatic life and migratory birds.

The plant's treated effluent flows into the local waterways of the Gan River basin, which drains into Poyang Lake, the largest freshwater lake in China. Poyang Lake is a vital wetland ecosystem that supports a rich diversity of fish, birds, and aquatic plants, and serves as a key stopover for migratory waterfowl along the East Asian-Australasian Flyway. The lake's ecological health is closely tied to the quality of inflowing waters, making the plant's treatment performance important for maintaining downstream water quality and biodiversity.
