Overview
Jilin wastewater treatment plant serves 180,000 people in Luyuan District, Changchun, Jilin Province, China. The facility operates under China's national wastewater discharge standards.
The Jilin wastewater treatment plant is located in Luyuan District, Changchun, Jilin Province, China. It serves a population of approximately 180,000, classifying it as a medium-to-large agglomeration under China's urban wastewater treatment framework. The facility is situated in the northeastern region of China, an area with cold winters and a significant industrial base. China's wastewater treatment regulations, governed by the Ministry of Ecology and Environment, require secondary treatment for urban plants serving populations over 100,000. For plants of this scale, discharge standards typically align with Grade 1-A or 1-B of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which includes limits on COD, BOD, ammonia nitrogen, and phosphorus. The regulatory framework ensures a minimum level of treatment. The plant discharges treated effluent into the local water system, which ultimately drains into the Songhua River basin. The Songhua River flows through Jilin and Heilongjiang provinces before reaching the Amur River and the Sea of Okhotsk. The river supports diverse aquatic life and is an important water source for agriculture and industry in the region.
Environmental context
The plant's treated effluent enters the local drainage network, which flows into the Songhua River basin. The Songhua River is a major tributary of the Amur River, eventually reaching the Sea of Okhotsk. This watershed supports a variety of fish species and provides water for irrigation and industrial use. The region's cold climate and seasonal ice cover influence treatment efficiency and discharge management.
