Liaoning Wastewater Treatment Plant, Shenyang - Large-Scale Municipal Facility

The Liaoning wastewater treatment plant is located in Shenyang, the capital of Liaoning Province, China. It serves a population of approximately 1,000,000 people, classifying it as a large agglomeration under Chinese wastewater regulations. The plant is situated in the Heping District, near the Hun River, a major tributary of the Liao River. As a large-scale facility, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates advanced treatment with nutrient removal for plants serving over 500,000 people. The plant likely employs biological treatment processes such as activated sludge or A2O to achieve these standards. Typical plants of this scale have capacities exceeding 200,000 m³/day. The treated effluent is discharged into the Hun River, which flows into the Liao River and eventually reaches the Bohai Sea. The plant plays a critical role in protecting the Liao River basin from pollution, supporting aquatic life and downstream water quality. The region's industrial and urban runoff further underscores the importance of effective wastewater management.

The plant discharges into the Hun River, a tributary of the Liao River, which flows into the Bohai Sea. The Liao River basin is ecologically sensitive, supporting diverse aquatic species and serving as a vital water resource for agriculture and industry. Effective treatment is essential to prevent eutrophication and protect the marine environment of the Bohai Sea.
