Overview
Jilin wastewater treatment plant serves 61,000 people in Changchun, Jilin Province, China. It operates under national water pollution control standards for municipal wastewater.
The Jilin wastewater treatment plant is located in Wukeshu Town, Changchun City, Jilin Province, China. It serves a population of approximately 61,000, classifying it as a medium-sized agglomeration under Chinese municipal wastewater management frameworks. The plant is situated inland, away from coastal areas, and its operations are part of the broader water infrastructure serving the region. The plant is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For a plant of this scale, secondary biological treatment with nutrient removal is typical to meet the required standards. The population served suggests a capacity in the range of tens of thousands of cubic meters per day. The treated effluent is discharged into local water bodies that ultimately drain into the Songhua River basin, a major river system in Northeast China. The Songhua River flows through Jilin and Heilongjiang provinces before reaching the Amur River and the Sea of Okhotsk. The plant plays a key role in protecting downstream water quality and aquatic ecosystems in this important agricultural and industrial region.
Environmental context
The plant discharges into local waterways that are part of the Songhua River basin, which drains into the Amur River and eventually the Sea of Okhotsk. The Songhua River supports diverse aquatic life and is a critical water resource for agriculture and industry in Northeast China. The region experiences cold winters, which can affect treatment efficiency, and the river is subject to seasonal ice cover. Protecting this watershed is essential for maintaining ecological balance and water quality for downstream communities.
