Overview
Gansu wastewater treatment plant serves Yongdeng County in Gansu Province, China, with a population equivalent of 42,200. The facility operates under China's national wastewater discharge standards.
The Gansu wastewater treatment plant is located in Yongdeng County, Gansu Province, China, serving a population of approximately 42,200. As a municipal facility in an inland region, it plays a key role in managing local wastewater from residential and commercial sources. Under China's national wastewater treatment regulations, plants serving agglomerations of this size are typically required to meet Class 1A or 1B discharge standards under the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). These standards mandate secondary biological treatment with nutrient removal in sensitive areas. The regulatory framework ensures a minimum level of treatment appropriate for the population served. The treated effluent is discharged into local water bodies that ultimately drain into the Yellow River basin, a major river system in northern China. The plant's operation helps protect downstream aquatic ecosystems and supports water quality in the region, which faces challenges from agricultural runoff and industrial activities.
Environmental context
The plant discharges into local waterways that are part of the Yellow River basin, one of China's most important river systems. The Yellow River flows through arid and semi-arid regions, supporting agriculture, industry, and millions of people. Downstream ecosystems include wetlands and lakes that provide critical habitat for migratory birds and aquatic species. Effective wastewater treatment is essential to prevent eutrophication and maintain water quality in this water-stressed region.
Frequently asked questions
The Gansu wastewater treatment plant is located in Yongdeng County, Gansu Province, China. Its coordinates are approximately 36.74 N, 103.256 E.
The plant serves a population equivalent of 42,200 people, classifying it as a medium-sized agglomeration under Chinese wastewater regulations.
The treated effluent is discharged into local water bodies that are part of the Yellow River basin. The plant must comply with China's national discharge standards to protect downstream water quality.
The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for organic matter, nutrients, and other pollutants. Plants serving over 20,000 people are typically required to achieve secondary treatment or higher.
For agglomerations of this size, Chinese regulations generally mandate secondary biological treatment with nutrient removal, especially if the receiving water body is in a sensitive area. The specific treatment process may include activated sludge or similar technologies.
