Jilin Wastewater Treatment Plant: Serving 109,000 People in Jilin City, China

The Jilin wastewater treatment plant is located in Jilin City, Jilin Province, China, serving an estimated population of 109,000. The plant is situated in an inland area, more than 50 km from the coast, and its operations are part of the municipal infrastructure for the region. The plant is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for various pollutants. For a plant serving over 100,000 people, secondary treatment with nutrient removal is typically required to meet these standards. The treated effluent is likely discharged into a local waterway that eventually drains into the Songhua River basin, a major river system in northeastern China. The Songhua River flows through Jilin Province and ultimately into the Amur River (Heilongjiang) and the Sea of Okhotsk. The plant plays a key role in protecting the water quality of this important river system.

The plant discharges into the Songhua River basin, which flows through Jilin Province and into the Amur River, eventually reaching the Sea of Okhotsk. The Songhua River supports diverse aquatic life and is an important water source for agriculture and industry. Proper treatment is essential to prevent eutrophication and protect downstream ecosystems.
