Overview
Jilin wastewater treatment plant serves Dehui City in Jilin Province, China, with a population equivalent of 161,000. The facility operates under China's national wastewater discharge standards.
The Jilin wastewater treatment plant is located in Shengli Subdistrict, Dehui City, within the Changchun prefecture of Jilin Province, China. Serving a population equivalent of 161,000, the plant is a key municipal infrastructure for the region. Dehui is situated in the fertile Songnen Plain, an area with significant agricultural activity. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), set effluent limits for conventional pollutants and nutrients. For a plant of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water's sensitivity. The treated effluent is discharged into local waterways that ultimately drain into the Songhua River basin, a major tributary of the Amur River system. The Songhua River supports diverse aquatic life and provides water for irrigation and industry downstream. Proper treatment is essential to protect water quality in this ecologically important basin.
Environmental context
The plant discharges into the Songhua River basin, which flows northeast through Jilin and Heilongjiang provinces before joining the Amur River and emptying into the Sea of Okhotsk. The basin supports a variety of fish species and is an important migratory corridor for birds. Downstream areas rely on the river for drinking water and agriculture, making nutrient and pollutant control critical.
