Overview
Gansu wastewater treatment plant serves Nanlong Town, Linxia City, Gansu Province, China, with a population of 59,500. It operates under China's national wastewater standards for medium-sized agglomerations.
The Gansu wastewater treatment plant is located in Nanlong Town, Linxia City, within the Gansu Province of China. It serves a population of approximately 59,500, classifying it as a medium-sized agglomeration under Chinese wastewater management frameworks. The facility is situated along the Nanbinhe Middle Road, near the Daxia River, which flows through the region. As a medium-scale plant, it is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment as a baseline. For plants serving populations over 50,000, stricter nutrient removal standards may apply, particularly if the receiving water body is designated as a sensitive area. Typical configurations for this scale include activated sludge systems with biological nutrient removal. The treated effluent is discharged into the Daxia River, a tributary of the Yellow River. The Daxia River flows through Linxia before joining the Yellow River downstream, which ultimately drains into the Bohai Sea. The plant plays a crucial role in protecting the Daxia River's water quality, supporting aquatic life and downstream communities that rely on the Yellow River basin for water supply and irrigation.
Environmental context
The plant discharges into the Daxia River, a tributary of the Yellow River. The Yellow River basin is a critical water resource for northern China, supporting agriculture, industry, and domestic use. The Daxia River section near Linxia is ecologically sensitive, hosting diverse aquatic species and providing habitat for migratory birds. Downstream, the Yellow River flows through arid regions where water quality is vital for irrigation and ecosystem health. The plant's operations help mitigate nutrient and pollutant loads, reducing the risk of eutrophication in the river and its eventual discharge into the Bohai Sea.
