Overview
Jilin wastewater treatment plant serves Nong'an County, Changchun, Jilin, China, with a population of 180,000. The plant operates under China's national wastewater discharge standards.
Jilin wastewater treatment plant is located in Nong'an County, Changchun, Jilin Province, China. It serves a population of approximately 180,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The facility is situated inland, away from coastal areas, and its operations are part of the broader municipal infrastructure for the region. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations of this scale are typically required to achieve at least secondary treatment, with some requiring advanced treatment to meet local water quality targets. Regulatory expectations for facilities of this size emphasize nutrient removal and compliance with effluent limits for receiving waters. The plant discharges treated effluent into local water bodies that ultimately drain into the Songhua River basin, a major river system in Northeast China. The Songhua River flows through Jilin and Heilongjiang provinces before reaching the Amur River and the Sea of Okhotsk. The plant plays a key role in protecting downstream water quality and supporting aquatic ecosystems in the region.
Environmental context
The plant's treated effluent enters local waterways within the Songhua River basin, which drains into the Amur River and eventually the Sea of Okhotsk. The Songhua River supports diverse aquatic life and provides water for agriculture and industry. Downstream areas include ecologically sensitive wetlands and floodplains that rely on good water quality for migratory birds and fish species. The plant's discharge standards help mitigate nutrient pollution and protect these downstream environments.
