Overview
Liaoning wastewater treatment plant serves Zhangwu County in Liaoning Province, China, with a population of 77,400. The facility operates under China's national wastewater discharge standards.
The Liaoning wastewater treatment plant is located in Zhangwu County, Liaoning Province, China. It serves a population of approximately 77,400, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), set effluent limits for conventional pollutants and nutrients. For plants of this scale, secondary treatment with nutrient removal is typical, especially in areas with sensitive receiving waters. The plant's operational context aligns with national efforts to improve water quality in the Liao River basin. The treated effluent from the plant likely discharges into a local waterway that eventually flows into the Liao River system, which drains into the Bohai Sea. This downstream connection underscores the plant's role in protecting both freshwater ecosystems and coastal marine environments from nutrient pollution and other contaminants.
Environmental context
The plant's discharge likely enters a tributary of the Liao River, which flows through Liaoning Province and empties into the Bohai Sea. The Liao River basin supports diverse aquatic life and is ecologically sensitive due to industrial and agricultural runoff. Effective treatment at this plant helps reduce nutrient loading and protects downstream habitats, including coastal wetlands and fisheries in the Bohai Sea.
