Overview
Gansu wastewater treatment plant serves 350,000 people in Sandun Town, Jiuquan, Gansu Province, China. It operates under national wastewater regulations for large agglomerations.
The Gansu wastewater treatment plant is located in Sandun Town (三墩镇), within the Suzhou District of Jiuquan City, Gansu Province, China. It serves a population of approximately 350,000, classifying it as a large-scale municipal facility under Chinese wastewater management standards. The plant is situated inland, away from coastal areas, and its operations are integral to the region's water infrastructure. As a large agglomeration serving over 100,000 people, the plant is expected to meet China's national discharge standards, which typically require secondary treatment or higher. Regulatory frameworks in China mandate that such plants comply with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits for key pollutants. The plant discharges treated effluent into local water bodies within the Hexi Corridor, an arid region where water resources are critical. The receiving waters ultimately drain into inland basins or terminal lakes, supporting agricultural and ecological needs. Proper treatment is essential to protect downstream water quality and sustain local ecosystems.
Environmental context
The plant serves the Hexi Corridor, a semi-arid region where water scarcity heightens the importance of wastewater treatment. Treated effluent likely flows into local rivers or streams that drain into inland terminal lakes, such as those in the Badain Jaran Desert area. These water bodies support fragile ecosystems and are vital for irrigation and wildlife. Protecting water quality is crucial to prevent salinization and eutrophication in this sensitive environment.
