Overview
Jilin wastewater treatment plant serves Dalaixiang, Jilin, China, with a population of 149,800. It operates under China's national wastewater standards.
The Jilin wastewater treatment plant is located in Dalaixiang, a township in Da'an City, Baicheng, Jilin Province, China. Serving a population of approximately 149,800, the plant is part of the municipal infrastructure for this region in northeastern China. Under China's national wastewater discharge standards (GB 18918-2002), treatment plants serving populations over 100,000 are typically required to meet Class 1-A or 1-B effluent standards, which mandate advanced treatment including nutrient removal. Facilities of this scale in China often employ activated sludge processes with biological nutrient removal to comply with stringent discharge limits. The plant discharges into the local watershed, which ultimately drains into the Songhua River basin. The Songhua River flows northeast through Jilin and Heilongjiang provinces before joining the Amur River (Heilongjiang) and eventually reaching 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 receiving water body is part of the Songhua River basin, which drains into the Amur River and the Sea of Okhotsk. The watershed supports diverse aquatic ecosystems, including migratory fish species. Downstream areas rely on the river for irrigation and drinking water, making effluent quality critical for both ecological and human health.
