Jilin Wastewater Treatment Plant, Tongyu County, Jilin Province, China

The Jilin wastewater treatment plant is situated in Tongyu County, Baicheng City, Jilin Province, China. It serves a population of approximately 96,500 people, classifying it as a medium-sized agglomeration under typical Chinese municipal wastewater management frameworks. The plant is located inland, far from coastal zones, and its operations are part of the region's water infrastructure. Chinese wastewater treatment plants of this scale are generally subject to national discharge standards under the Environmental Protection Law and the Water Pollution Prevention and Control Law. These regulations typically require secondary treatment or higher for municipal wastewater, with effluent limits tailored to the receiving environment. The plant's treated effluent likely discharges into local water bodies that eventually drain into the Nen River system, a major tributary of the Songhua River, which flows into the Amur River and ultimately the Sea of Okhotsk. The facility plays a key role in protecting downstream water quality and aquatic ecosystems in the region.

The plant is located in the inland region of Jilin Province, within the drainage basin of the Nen River, a tributary of the Songhua River. The Songhua River flows into the Amur River, which empties into the Sea of Okhotsk. The surrounding watershed supports diverse aquatic life and is important for regional agriculture and fisheries. Effective wastewater treatment is essential to prevent nutrient pollution and maintain ecological balance in these downstream water bodies.
