Overview
Gansu wastewater treatment plant serves 72,900 people in Anding District, Dingxi, Gansu, China. It discharges into the local river system within the Yellow River basin.
The Gansu wastewater treatment plant is located in Anding District, Dingxi City, Gansu Province, China. It serves a population of approximately 72,900, classifying it as a medium-sized agglomeration under Chinese wastewater management standards. The plant is situated along Guanchuan East Road in the Zhonghua Road Subdistrict, within the urban area of Dingxi. As a municipal facility in China, the plant operates under the national discharge standards set by the Ministry of Ecology and Environment, which require secondary or advanced treatment for urban wastewater. Plants of this scale typically employ biological treatment methods such as activated sludge or sequencing batch reactors to meet Class 1A or 1B discharge limits. The treated effluent is discharged into the local watercourse, which flows into the Wei River, a tributary of the Yellow River. The Yellow River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry in northern China. The plant's operation helps reduce pollution loads entering this critical river system, contributing to the protection of downstream water quality and ecosystem health.
Environmental context
The plant discharges into a local stream that flows into the Wei River, a major tributary of the Yellow River. The Yellow River basin is a vital water resource for northern China, supporting irrigation, industry, and domestic use. The region's semi-arid climate makes water quality management crucial for maintaining aquatic habitats and preventing eutrophication in downstream reservoirs.
