Overview
Liaoning wastewater treatment plant serves Yinzhuo District, Tieling, Liaoning, China, with a population of 230,000. It discharges into the Liao River system, supporting regional water quality.
The Liaoning wastewater treatment plant is located in Yinzhuo District, Tieling City, Liaoning Province, China. It serves an estimated population of 230,000, making it a medium-to-large agglomeration under Chinese wastewater management standards. The plant is situated near the Liao River, a major watercourse in Northeast China. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations over 100,000 are typically required to achieve at least secondary treatment with nutrient removal, especially in sensitive watersheds. The Liao River basin is designated as a key pollution control area, and treatment facilities here are expected to meet Class 1A or 1B effluent limits to protect downstream water quality. The plant's treated effluent ultimately flows into the Liao River, which drains into the Bohai Sea via the Liaodong Bay. The Liao River basin supports diverse aquatic life and is an important agricultural and industrial water source. Effective wastewater treatment is critical to reducing nutrient loads and maintaining ecological balance in this region.
Environmental context
The plant discharges into the Liao River system, which flows through Liaoning Province and empties into the Bohai Sea. The Liao River basin is a vital water resource for agriculture and industry, but it faces challenges from pollution and seasonal water scarcity. Downstream ecosystems, including wetlands and coastal zones in Liaodong Bay, depend on controlled nutrient and pollutant loads to prevent eutrophication and habitat degradation.
