Overview
Jilin wastewater treatment plant serves 81,000 people in Jilin City, Jilin Province, China. The facility operates under China's national wastewater discharge standards.
The Jilin wastewater treatment plant is located in the Changyi District of Jilin City, Jilin Province, China. It serves a population of approximately 81,000, placing it in the medium-sized agglomeration category for Chinese municipal wastewater infrastructure. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), mandate secondary treatment with nutrient removal for plants of this scale. Typical facilities in this region employ activated sludge processes to meet Class 1A or 1B discharge standards. The plant discharges treated effluent into local waterways that eventually drain into the Songhua River basin, a major tributary of the Amur River system. The Songhua River supports diverse aquatic life and provides water for agricultural and industrial use downstream. Proper treatment is essential to protect water quality in this ecologically and economically important watershed.
Environmental context
The Jilin plant discharges into the Songhua River basin, which flows northeast through Heilongjiang Province before joining the Amur River and ultimately reaching the Sea of Okhotsk. The Songhua River supports a variety of fish species and provides critical habitat for migratory birds. Downstream water quality is important for drinking water supplies and fisheries in the region.
