Overview
Jilin wastewater treatment plant serves 1.68 million people in Jilin City, China. It operates under national water pollution control standards for large agglomerations.
The Jilin wastewater treatment plant is a major municipal facility serving approximately 1.68 million residents in Jilin City, located in Jilin Province, China. As a large-scale plant, it plays a critical role in managing the city's domestic and industrial wastewater within the Songhua River basin. China's wastewater treatment regulations require large agglomerations to achieve at least secondary treatment, with stricter standards for plants discharging into sensitive water bodies. The plant's scale suggests it likely employs advanced treatment processes to meet Class 1A or 1B discharge standards under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The treated effluent is discharged into the Songhua River system, which flows through northeastern China and eventually into the Sea of Japan via the Tumen River. The river supports diverse aquatic life and provides water for downstream communities, making effective treatment essential for ecological and public health protection.
Environmental context
The plant discharges into the Songhua River, a major tributary of the Amur River basin. The river flows through Jilin and Heilongjiang provinces before reaching the Sea of Japan. The downstream environment supports fisheries and agricultural irrigation, and the river is ecologically sensitive due to its role as a migratory corridor for fish species. Proper treatment is critical to prevent eutrophication and protect water quality in this transboundary basin.
