Overview
Jilin wastewater treatment plant serves Siping City, Jilin Province, China, with a population equivalent of 94,500. The facility operates under China's national wastewater discharge standards.
The Jilin wastewater treatment plant is located in Siping City, Jilin Province, China, serving an estimated population of 94,500. This medium-sized agglomeration is part of the municipal infrastructure for the region, treating domestic and industrial wastewater from the urban area. As a facility in China, the plant is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for key parameters. 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 body's sensitivity. The treated effluent is discharged into local waterways that ultimately drain into the Liao River basin, an important water system in northeastern China. The Liao River flows into the Bohai Sea, supporting diverse aquatic life and providing water for agriculture and industry downstream. Proper treatment is essential to protect these ecological and economic resources.
Environmental context
The plant discharges into the Liao River basin, which flows through Jilin and Liaoning provinces before emptying into the Bohai Sea. This watershed supports fisheries, irrigation, and industrial water use. The Bohai Sea is a semi-enclosed marginal sea with significant ecological importance, hosting diverse marine species and serving as a critical migratory corridor for birds. Effective wastewater treatment is crucial to prevent eutrophication and protect coastal water quality.
