Overview
Jilin wastewater treatment plant serves Huinan County in Jilin Province, China, with a population equivalent of 105,000. The facility operates under China's national wastewater discharge standards.
The Jilin wastewater treatment plant is located in Dongfeng Subdistrict, Huinan County, Tonghua City, Jilin Province, China. It serves a population equivalent of approximately 105,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management frameworks. The plant is situated inland, away from coastal areas, and its treated effluent is discharged into local water bodies that eventually drain into the broader Songhua River basin. As a facility serving over 100,000 people, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants of this scale. The regulatory framework also requires compliance with Class 1A or 1B effluent limits depending on the receiving water's sensitivity. The plant's design aligns with national standards for urban wastewater treatment. The plant's receiving water body is part of the Liao River or Songhua River watershed, both of which are ecologically significant in Northeast China. The region's cold climate and seasonal variations influence treatment operations. Downstream, the water contributes to agricultural irrigation and supports aquatic ecosystems. The plant plays a key role in protecting local water quality and public health in Huinan County.
Environmental context
The plant discharges into a tributary of the Liao River or Songhua River system, which flows through Jilin Province and ultimately reaches the Bohai Sea. The watershed supports diverse aquatic life and is used for irrigation and industrial water supply. Seasonal ice cover and low winter temperatures pose challenges for biological treatment processes, requiring robust operational management to maintain effluent quality.
