Overview
Jilin wastewater treatment plant serves the Lüyuan district of Changchun, China, with a population equivalent of 200,000. The facility operates under China's national wastewater discharge standards.
The Jilin wastewater treatment plant is located in the Lüyuan district of Changchun, Jilin Province, China. It serves a population equivalent of 200,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management frameworks. As a facility serving this scale, it is expected to meet the discharge standards set by China's Ministry of Ecology and Environment, which typically require secondary biological treatment with nutrient removal for plants of this size. The plant's design and operation align with national policies aimed at reducing pollution in urban water bodies. The treated effluent likely discharges into a local waterway within the Songhua River basin, which flows northeast into the Amur River and ultimately into the Sea of Okhotsk. The plant plays a key role in protecting downstream aquatic ecosystems and supporting water quality in the region.
Environmental context
The plant is situated inland in 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, the Amur River forms a critical ecological corridor for migratory fish species, including salmon. Protecting water quality in this basin is essential for maintaining regional biodiversity and ecosystem health.
