Jilin Wastewater Treatment Plant, Meihekou City, Jilin Province, China

The Jilin wastewater treatment plant is located in Meihekou City, Tonghua Prefecture, Jilin Province, China. It serves a population equivalent of 208,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant is situated in the temperate continental monsoon climate zone, where seasonal variations influence treatment demands. As a large-scale municipal facility, the plant is expected to meet national discharge standards under China's Water Pollution Prevention and Control Law. Chinese regulations require secondary treatment as a baseline for urban wastewater, with tertiary treatment increasingly mandated in sensitive watersheds. The plant's treatment process and capacity details are not publicly available, but its scale suggests robust infrastructure to handle the city's wastewater load. The treated effluent likely discharges into the Huifa River, a tributary of the Liao River system, which flows into the Bohai Sea. The Liao River basin supports intensive agriculture and industrial activity, making effective wastewater treatment critical for protecting downstream water quality and aquatic ecosystems.

The plant's discharge enters the Huifa River, which flows into the Liao River and ultimately reaches the Bohai Sea. The Liao River basin is a major agricultural and industrial region in Northeast China, facing challenges from nutrient pollution and industrial contaminants. Effective treatment at this plant helps reduce the ecological burden on the river system and the marine environment of the Bohai Sea, which supports diverse fisheries and migratory bird populations.
