Overview
Jilin wastewater treatment plant serves Yushu City, Jilin Province, China, with a population of 230,000. The facility operates under national wastewater regulations for large agglomerations.
The Jilin wastewater treatment plant is located in Yushu City, Jilin Province, China, serving a population of approximately 230,000. The facility is situated in the northeastern region of China, an area characterized by a continental monsoon climate with cold winters and warm summers. As a large agglomeration, the plant plays a critical role in managing municipal wastewater for the urban area. Plants of this scale in China are typically required to meet national discharge standards under the Environmental Protection Law and the Water Pollution Prevention and Control Law. Large urban wastewater treatment facilities in China often employ secondary or advanced treatment processes to comply with effluent quality standards, particularly for sensitive receiving waters. The plant's treated effluent is discharged into local water bodies that eventually drain into the Songhua River basin, a major river system in Northeast China. The Songhua River flows through Jilin and Heilongjiang provinces before reaching the Amur River (Heilongjiang) and ultimately the Sea of Okhotsk. The river supports diverse aquatic life and is an important water resource for agriculture, industry, and drinking water downstream.
Environmental context
The plant's receiving water body is part of the Songhua River basin, which drains into the Amur River and then the Sea of Okhotsk. The Songhua River is ecologically significant, supporting fish species such as the Amur sturgeon and serving as a migratory corridor for birds. The watershed faces pressures from agricultural runoff and industrial activities, making effective wastewater treatment crucial for maintaining water quality and ecosystem health.
