Liaoning Wastewater Treatment Plant, Jianchang, Liaoning, China

The Liaoning wastewater treatment plant is located in Jianchang town, Jianchang County, Huludao City, Liaoning Province, China. It serves a population of approximately 77,000 people, classifying it as a medium-sized agglomeration under Chinese wastewater management standards. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on the receiving water's environmental sensitivity. For plants serving populations of this scale, secondary treatment with nutrient removal is typically required, especially if discharging into sensitive water bodies. The plant's treated effluent is released into local rivers that drain into the Bohai Sea via the Liao River system. The downstream environment supports diverse aquatic life and is important for regional fisheries and agriculture. Proper treatment helps protect water quality in this densely populated and industrially active region.

The plant discharges into local waterways that flow into the Liao River system, eventually reaching the Bohai Sea. This coastal sea area supports important fisheries and migratory bird habitats. The region faces challenges from industrial and agricultural runoff, making effective wastewater treatment critical for maintaining water quality and ecosystem health.
