Jilin wastewater treatment plant serves Changchun, Jilin province, China, with a population of 920,000. It operates under China's national wastewater standards for large urban agglomerations.
The Jilin wastewater treatment plant is located in Changchun, the capital of Jilin province, China. It serves a population of approximately 920,000, placing it in the category of large urban agglomerations requiring advanced treatment under Chinese regulations. As a major facility in northeastern China, the plant is expected to meet the discharge standards set by the Chinese Ministry of Ecology and Environment, which mandate secondary or tertiary treatment for cities of this scale. The plant's operations are likely overseen by municipal authorities, with permits issued under the national Water Pollution Prevention and Control Law. The treated effluent is discharged into local waterways that ultimately drain into the Songhua River basin, a critical water system in Northeast China. The Songhua River flows through Jilin and Heilongjiang provinces before reaching the Amur River and the Sea of Okhotsk, supporting diverse aquatic life and regional agriculture.
Environmental context
The plant discharges into the Songhua River basin, which flows through Jilin and Heilongjiang provinces into the Amur River and the Sea of Okhotsk.
