Overview
Jilin wastewater treatment plant serves Songyuan City, Jilin Province, China, with a population equivalent of 81,600. The facility operates under China's national wastewater discharge standards.
The Jilin wastewater treatment plant is located in Songyuan City, Jilin Province, China, serving a population of approximately 81,600. It is situated in the northeastern part of the country, an area characterized by a continental monsoon climate with cold winters and warm summers. As a medium-sized agglomeration, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets limits for key pollutants such as COD, BOD, ammonia nitrogen, and phosphorus. Treatment typically includes biological processes like activated sludge, with nutrient removal required for plants discharging into sensitive water bodies. The treated effluent is likely discharged into a local river or stream that eventually drains into 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, making proper wastewater treatment essential for ecological health.
Environmental context
The plant's receiving water body is part of the Songhua River basin, which flows northeast into the Amur River and ultimately into the Sea of Okhotsk. The basin supports important fisheries and provides water for irrigation and municipal use. Effective treatment helps protect downstream ecosystems from nutrient pollution and organic loading.
