The Jilin wastewater treatment plant is located in Siping, Jilin Province, China, serving a population equivalent of 130,000. The plant is part of the municipal infrastructure for the city of Siping, situated in the northeastern part of the country. As a facility serving over 100,000 people, it falls under China's national wastewater discharge standards (GB 18918-2002), which require secondary treatment as a minimum. Typical plants of this scale in China employ activated sludge processes with nutrient removal to meet Class 1A or 1B discharge standards. The treated effluent is discharged into local water bodies that ultimately drain into the Liao River basin, which flows into the Bohai Sea. The plant plays a crucial role in protecting downstream aquatic ecosystems and supporting regional water quality objectives.
