Overview
Liaoning wastewater treatment plant serves 52,000 people in Hongwei District, Liaoyang, Liaoning Province, China. It operates under national wastewater standards for medium-sized agglomerations.
Liaoning wastewater treatment plant is located in Hongwei District, Liaoyang City, Liaoning Province, China. It serves a population of approximately 52,000, classifying it as a medium-sized agglomeration under Chinese wastewater management frameworks. The plant is situated in an industrial area near Liaoyang Petrochemical, reflecting the region's mixed urban and industrial character. As a facility serving over 50,000 people, Liaoning plant is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This national regulation sets effluent limits for biochemical oxygen demand, chemical oxygen demand, suspended solids, and nutrients, with stricter requirements for plants discharging into sensitive water bodies. The plant's operational context aligns with China's broader efforts to improve water quality in the Liao River basin. The plant's treated effluent ultimately drains into the Liao River system, which flows through Liaoning Province into the Bohai Sea. The Liao River basin supports diverse aquatic life and is an important agricultural and industrial water source. Downstream, the Bohai Sea is a semi-enclosed marginal sea with significant ecological and economic value, hosting fisheries and marine biodiversity. The plant's performance directly influences water quality in this sensitive coastal environment.
Environmental context
The plant discharges into the Liao River basin, which flows through Liaoning Province and empties into the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea with limited water exchange, making it vulnerable to nutrient pollution and algal blooms. The Liao River supports diverse aquatic ecosystems and provides water for agriculture and industry. Effective wastewater treatment is critical to protect downstream water quality and marine habitats.
