Overview
Gansu wastewater treatment plant serves Baiyin District in Gansu, China, with a population equivalent of 200,000. The facility operates under China's national wastewater discharge standards.
Gansu wastewater treatment plant is located in the western district of Baiyin, a city in Gansu Province, China. The facility serves a population of approximately 200,000 people, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management. The plant is situated inland, far from coastal waters, and its treated effluent likely discharges into local rivers or water bodies within the Yellow River basin. As a Chinese municipal wastewater treatment plant serving a population of 200,000, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). This national standard sets limits for key pollutants such as COD, BOD, ammonia nitrogen, and phosphorus, with stricter requirements for plants discharging into sensitive water bodies. The plant likely employs conventional secondary treatment processes such as activated sludge or oxidation ditch to meet these standards. Given its location in Baiyin, the treated wastewater likely flows into the Yellow River system via tributaries such as the Yellow River itself or the Wei River. The Yellow River is a major water source for northern China, and its ecological health is critical for agriculture, industry, and domestic use downstream. Proper treatment at this plant helps protect water quality in the basin.
Environmental context
The plant discharges into the Yellow River basin, which ultimately flows into the Bohai Sea. The Yellow River is a vital water source for northern China, supporting irrigation, industry, and ecosystems. Downstream areas include the Hetao Plain and the Yellow River Delta, which provide important habitats for migratory birds and aquatic species. Effective wastewater treatment is essential to prevent eutrophication and protect biodiversity in this ecologically sensitive region.
