Overview
Gansu wastewater treatment plant serves Dunhuang, China, with a population equivalent of 26,800. The facility operates under China's national wastewater discharge standards.
The Gansu wastewater treatment plant is located in Suzhou Town, Dunhuang City, Jiuquan, Gansu Province, China. It serves a population of approximately 26,800, classifying it as a medium-sized agglomeration under Chinese municipal wastewater management. As a plant in China, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits for key pollutants. For a facility of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The plant discharges into the local watershed within the arid Hexi Corridor region. Treated effluent likely flows into the Shule River basin or evaporates in the Gobi Desert environment. The downstream area supports sparse vegetation and seasonal wetlands, making water quality management critical for local ecosystems and agricultural reuse.
Environmental context
The plant is located in the Hexi Corridor, an arid region where water resources are scarce. Treated wastewater likely discharges into the Shule River system, which ultimately drains into terminal lakes or evaporates in the Gobi Desert. The local watershed supports fragile desert ecosystems and agricultural irrigation, making effluent quality essential for preventing salinization and protecting downstream biodiversity.
