Overview
Guizhou wastewater treatment plant serves Shuicheng District in Liupanshui, Guizhou, China, with a population equivalent of 50,000. It operates under China's national wastewater standards.
The Guizhou wastewater treatment plant is located in Shuicheng District, Liupanshui City, Guizhou Province, China. It serves a population equivalent of approximately 50,000, classifying it as a medium-sized municipal facility within the region's water infrastructure network. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. 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's treated effluent is discharged into local waterways that ultimately drain into the Yangtze River basin via the Wujiang River system. This downstream connection to the Yangtze underscores the plant's role in protecting water quality in one of China's most ecologically and economically significant river systems.
Environmental context
The plant discharges into the Wujiang River system, a major tributary of the upper Yangtze River. The Wujiang flows through karst landscapes in Guizhou before joining the Yangtze at Fuling, Chongqing. The downstream environment supports diverse aquatic life and provides water for agriculture and urban use. The plant's nutrient removal performance is critical to preventing eutrophication in the Yangtze estuary and coastal waters of the East China Sea.
