Overview
Liaoning wastewater treatment plant serves Taizihe District, Liaoyang, China, with a population of 320,000. It operates under China's national wastewater standards.
The Liaoning wastewater treatment plant is located in Taizihe District, Liaoyang, Liaoning Province, China. It serves a population of approximately 320,000, classifying it as a large-scale municipal facility within the region's urban wastewater infrastructure. As a large agglomeration, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants serving over 100,000 people. The plant's treatment processes and capacity are aligned with these national requirements to ensure compliance with environmental regulations. The treated effluent is discharged into local water bodies that ultimately flow into the Liao River basin, a major river system in Northeast China. The Liao River drains into the Bohai Sea, supporting diverse aquatic ecosystems and providing water for agricultural and industrial use downstream. The plant plays a critical role in protecting water quality in this densely populated and industrialized region.
Environmental context
The plant discharges into the Liao River basin, which flows through Liaoning Province and empties into the Bohai Sea. This watershed supports a variety of aquatic life and is vital for regional agriculture and industry. The Bohai Sea is a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution from upstream sources. The plant's treatment helps mitigate eutrophication risks in downstream waters.
