Overview
Guizhou wastewater treatment plant serves 159,000 people in Ximen Subdistrict, Kaili City, Guizhou, China. It operates under China's national wastewater standards for urban agglomerations.
The Guizhou wastewater treatment plant is located in Ximen Subdistrict, Kaili City, within Guizhou Province, China. It serves a population of 159,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The facility is situated inland, away from coastal zones, and its operations are integral to the region's water infrastructure. As a plant serving over 100,000 people, it is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with potential nutrient removal for sensitive water bodies. Regulatory requirements for this scale typically include biological treatment and disinfection. The plant discharges into local waterways that eventually drain into the Yangtze River basin, a critical water system supporting diverse aquatic life and agricultural activities. Its role in protecting downstream water quality is essential for the ecological health of the region, particularly given the dense population and industrial activities in Guizhou.
Environmental context
The plant's treated effluent likely enters the Qingshui River, a tributary of the Yuan River, which flows into Dongting Lake and ultimately the Yangtze River. This watershed supports a variety of freshwater species and provides water for irrigation and drinking. The region's karst topography makes groundwater particularly vulnerable to contamination, emphasizing the need for effective treatment to protect both surface and subsurface water resources.
