Overview
Liaoning wastewater treatment plant serves Yuhong District, Shenyang, Liaoning, China, with a population equivalent of 1,700,000. The facility operates under China's national wastewater discharge standards.
The Liaoning wastewater treatment plant is located in Yuhong District, Shenyang, Liaoning Province, China. It serves a large urban population of approximately 1,700,000 people, making it a significant municipal facility in the region. The plant is situated in the northern part of the country, where cold winters influence treatment operations. As a large-scale agglomeration, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which requires secondary treatment with nutrient removal for facilities serving over 100,000 people. The plant likely employs biological treatment processes such as activated sludge or A2O to achieve compliance with Class 1A or 1B standards, depending on the sensitivity of the receiving water body. The treated effluent is discharged into the local water system, which ultimately drains into the Liao River basin. The Liao River flows through Liaoning Province and empties into the Bohai Sea, a semi-enclosed marginal sea of the Pacific Ocean. The plant plays a crucial role in protecting the Liao River and Bohai Sea from excessive nutrient loading and organic pollution, supporting aquatic life and downstream water quality.
Environmental context
The plant discharges into the Liao River basin, which flows through Liaoning Province and into the Bohai Sea. The Bohai Sea is a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution from upstream sources. The Liao River receives industrial and agricultural runoff, and the plant's advanced treatment helps mitigate eutrophication risks in the coastal zone. The downstream environment supports diverse aquatic species and is an important fishing ground.
Frequently asked questions
The plant is located in Yuhong District, Shenyang, Liaoning Province, China, specifically in Beiling Subdistrict.
The plant serves approximately 1,700,000 people, classifying it as a large agglomeration under Chinese regulations.
The treated effluent is discharged into the local water system, which flows into the Liao River basin and ultimately reaches the Bohai Sea.
The plant must comply with China's GB 18918-2002 standard, which mandates secondary treatment with nutrient removal for large facilities. Discharge limits are set based on the receiving water's sensitivity.
For such large agglomerations, typical treatment includes biological nutrient removal (e. g. , A2O or SBR processes) to meet Class 1A or 1B standards, ensuring low levels of COD, BOD, nitrogen, and phosphorus.
