Overview
Liaoning wastewater treatment plant serves 300,000 people in Hongwei District, Liaoyang, Liaoning Province, China. It operates under national wastewater standards for large agglomerations.
The Liaoning wastewater treatment plant is located in Hongwei District, Liaoyang City, Liaoning Province, China. It serves a population of approximately 300,000, classifying it as a large agglomeration under Chinese wastewater management regulations. The facility is situated in an industrial area near Liaoyang Petrochemical, reflecting the region's mixed urban and industrial character. As a large-scale plant, it is expected to meet secondary or advanced treatment standards under China's national wastewater discharge limits (GB 18918-2002). Facilities of this scale typically employ biological treatment processes such as activated sludge or A2O to comply with effluent standards for receiving water bodies. The plant's treated effluent likely discharges into a local river within the Liao River basin, which flows into the Bohai Sea. The Liao River basin is a major industrial and agricultural region, and wastewater treatment plays a critical role in protecting downstream water quality and the marine environment of the Bohai Sea.
Environmental context
The plant is located in the Liao River basin, which drains into the Bohai Sea, a semi-enclosed marginal sea of the Pacific Ocean. The Bohai Sea supports diverse marine life and is an important fishing ground, but it faces eutrophication risks from nutrient loading. The plant's discharge contributes to the overall water quality of the Liao River and ultimately the Bohai Sea, making effective treatment essential for protecting downstream aquatic ecosystems and coastal waters.
