Overview
Jilin wastewater treatment plant serves Jiutai District, Changchun, Jilin Province, China. It treats wastewater from approximately 183,000 people, supporting the local urban infrastructure.
The Jilin wastewater treatment plant is located in Jiutai District, Changchun City, Jilin Province, China. It serves a population of approximately 183,000, making it a medium-to-large agglomeration under Chinese municipal wastewater standards. The plant is situated along Yanhe Street in Nanshan Subdistrict, within the broader urban area of Changchun. As a facility serving over 100,000 people, the plant is expected to meet secondary treatment standards as per China's national wastewater discharge regulations (GB 18918-2002). These standards require effective removal of organic matter and suspended solids, with some facilities also incorporating nutrient removal to protect receiving waters. The plant's operational details are managed within the municipal framework of Changchun's wastewater infrastructure. The plant discharges treated effluent into local water bodies that eventually 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 aquatic ecosystems and supporting water quality in the region.
Environmental context
The plant's treated effluent enters local waterways within the Songhua River basin, which drains northeastward through Jilin and Heilongjiang provinces. The Songhua River is a major tributary of the Amur River, ultimately reaching the Sea of Okhotsk. This watershed supports diverse aquatic life and provides water for agriculture and industry. The plant's discharge contributes to maintaining water quality in this ecologically significant river system.
