The Liaoning wastewater treatment plant is located in Xiaoming Town, Diaobingshan City, Liaoning Province, China. It serves a population equivalent of 180,000, classifying it as a medium-to-large urban agglomeration under Chinese regulatory frameworks. The plant is situated inland, approximately 50 km from the coast, and its operations are integral to the region's water management infrastructure. The plant is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For agglomerations serving over 100,000 people, Chinese regulations typically require secondary biological treatment with nutrient removal to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. Its population served suggests a substantial treatment capacity. The treated effluent likely discharges into a local river or watercourse within the Liao River basin, which ultimately flows into the Bohai Sea. The Liao River basin is a major industrial and agricultural region, and the plant plays a key role in protecting downstream water quality and aquatic ecosystems from urban pollution loads.
Environmental context
The plant's discharge enters a tributary of the Liao River system, which drains into the Bohai Sea. The Liao River basin supports diverse aquatic life and is an important water resource for agriculture and industry in northeastern China. The Bohai Sea is a semi-enclosed marginal sea with significant ecological and economic value, including fisheries and shipping. Effective wastewater treatment is critical to prevent eutrophication and protect marine biodiversity in this sensitive coastal environment.
