Overview
Gansu wastewater treatment plant serves Jiayuguan City, Gansu Province, China, with a population of 164,500. It operates under China's national wastewater discharge standards.
The Gansu wastewater treatment plant is located in Jiayuguan City, Gansu Province, China, serving an estimated population of 164,500. The facility is situated in an inland region, far from coastal areas, and is part of the municipal wastewater infrastructure for the city. As a plant serving a medium-sized agglomeration, it is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. Treatment typically includes secondary biological processes, with possible tertiary treatment for nutrient removal depending on local requirements. The treated effluent is discharged into local water bodies that eventually drain into the Heihe River basin, a major inland river system in northwestern China. The region's arid climate makes water reuse and protection of water quality critical for downstream ecosystems and agricultural use.
Environmental context
The plant discharges into the Heihe River basin, which flows through arid northwestern China and terminates in the Juyan Lake system. This inland basin supports fragile desert ecosystems and is a vital water source for agriculture and local communities. Protecting water quality in this basin is essential to prevent salinization and maintain ecological balance in a water-scarce region.
