Overview
Liaoning wastewater treatment plant serves Liaoyang, Liaoning, China, treating wastewater for approximately 95,000 people. The facility discharges into local waterways under China's national wastewater standards.
The Liaoning wastewater treatment plant is located in Xinglong Town, Liaoyang County, Liaoyang City, Liaoning Province, China. It serves an estimated population of 95,000, classifying it as a medium-sized municipal facility within the region's water infrastructure. The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For facilities serving populations around 95,000, secondary treatment with nutrient removal is typically required to meet Class 1A or 1B standards, depending on the receiving water body's sensitivity. The plant's treated effluent is discharged into local rivers that eventually flow into the Liao River basin, a major water system in Northeast China. The Liao River drains into the Bohai Sea, supporting diverse aquatic life and providing water for agriculture and industry. Proper treatment is crucial to protect downstream ecosystems and water quality in this densely populated region.
