Overview
Jilin wastewater treatment plant serves approximately 130,000 people in Lianhe Village, Taonan City, Jilin Province, China. The facility operates under China's national wastewater discharge standards.
The Jilin wastewater treatment plant is located in Lianhe Village, Taonan City, within Jilin Province, China. It serves a population of approximately 130,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management frameworks. The plant is situated inland, away from coastal zones, and its operations are governed by China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). Under Chinese regulations, plants serving populations over 100,000 are typically required to achieve at least secondary treatment with nutrient removal, especially in sensitive watersheds. The regulatory framework mandates compliance with effluent standards that protect receiving water bodies. The plant likely discharges into a local river or stream that drains into the broader Songhua River basin, a major water system in Northeast China. The receiving water body ultimately flows into the Songhua River, which is a significant tributary of the Amur River (Heilong Jiang) that empties into the Sea of Okhotsk. The watershed supports diverse aquatic life and is important for regional agriculture and industry. Proper treatment is essential to prevent eutrophication and protect downstream ecosystems.
Environmental context
The plant discharges into a local watercourse that is part of the Songhua River basin, which flows northeast into the Amur River and eventually the Sea of Okhotsk. This watershed is ecologically significant, supporting fisheries and migratory bird habitats. The region experiences cold winters, which can affect treatment efficiency, and the river system is vulnerable to nutrient loading from agricultural runoff. Effective wastewater treatment helps maintain water quality in this transboundary river system.
