Overview
The Jilin wastewater treatment plant serves Songyuan City in Jilin Province, China, with a population equivalent of 320,000. It operates under China's national wastewater discharge standards.
The Jilin wastewater treatment plant is located in Songyuan City, Jilin Province, China, within the Songyuan Economic and Technological Development Zone. It serves a population equivalent of 320,000, classifying it as a large-scale municipal facility in the region. As a major treatment plant in northeastern China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. For plants of this scale, secondary biological treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water's sensitivity. The plant discharges treated effluent into local waterways that ultimately flow into the Songhua River basin, a major tributary of the Amur River system. The Songhua River supports diverse aquatic life and provides water for agriculture and industry downstream. Proper treatment is critical to prevent eutrophication and protect water quality in this ecologically important watershed.
Environmental context
The plant's treated effluent enters the local drainage network within the Songhua River basin, which flows northeastward through Jilin and Heilongjiang provinces before joining the Amur River at the Russia-China border. The Songhua River supports a variety of fish species and provides drinking water for millions of people. Downstream ecosystems include wetlands and floodplains that serve as important habitats for migratory birds and aquatic organisms. Nutrient loading from untreated or inadequately treated wastewater could contribute to algal blooms and oxygen depletion in the river system.
