Overview
Jilin wastewater treatment plant serves 200,000 people in Jilin City, Jilin Province, China. The facility operates under China's national wastewater standards for large agglomerations.
The Jilin wastewater treatment plant is a municipal facility located in the Longtan District of Jilin City, Jilin Province, China. It serves a population of approximately 200,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant is situated in an industrial and urban area near the Songhua River basin. As a large-scale plant serving 200,000 people, it is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment as a minimum and often requires advanced treatment for sensitive receiving waters. Facilities of this size typically employ activated sludge processes with nutrient removal to comply with national effluent limits. The plant discharges treated wastewater into the local water system, ultimately flowing into the Songhua River, a major tributary of the Amur River basin. The Songhua River supports diverse aquatic life and provides water for downstream communities and agriculture. Proper treatment is critical to protect this ecologically important river system from eutrophication and pollution.
Environmental context
The Jilin plant discharges into the Songhua River, which flows northeast through Heilongjiang Province before joining the Amur River and emptying into the Sea of Okhotsk. The Songhua River basin is a vital water resource for northeastern China, supporting fisheries, irrigation, and industrial use. The river's ecological health is sensitive to nutrient loading and industrial pollutants, making advanced wastewater treatment essential for preserving water quality and aquatic biodiversity in this region.
