Overview
Guizhou wastewater treatment plant serves 62,000 people in Panzhou, Liupanshui, Guizhou, China. It operates under China's national wastewater standards for medium-sized agglomerations.
The Guizhou wastewater treatment plant is located in Panzhou, a county-level city under Liupanshui, in Guizhou Province, China. It serves a population of approximately 62,000, classifying it as a medium-sized municipal facility within the region's water infrastructure network. As a plant in China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. For a facility of this scale, secondary treatment with nutrient removal is typically required to meet Class 1A or 1B standards, especially in areas with downstream ecological sensitivity. The plant's treated effluent likely discharges into a local watercourse within the Yangtze River basin, as Guizhou Province drains into the Yangtze system. The receiving waters support diverse aquatic life and are important for regional agriculture and drinking water supplies downstream.
Environmental context
The plant discharges into a tributary of the Yangtze River basin, which ultimately flows to the East China Sea. The local watershed in Guizhou is characterized by karst topography, making groundwater and surface water closely connected. Protecting water quality is critical for downstream ecosystems, including fish spawning habitats and wetland areas that support migratory birds.
