Overview
The Guizhou wastewater treatment plant serves approximately 300,000 people in Zhongshan District, Liupanshui, Guizhou Province, China. It operates under China's national wastewater discharge standards.
The Guizhou wastewater treatment plant is located in Zhongshan District, Liupanshui, Guizhou Province, China. It serves a population of approximately 300,000, classifying it as a large-scale municipal facility within the region. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations over 100,000 are typically required to achieve at least secondary treatment, with many larger facilities implementing advanced treatment to meet stricter effluent limits for sensitive water bodies. The plant's treated effluent is discharged into local waterways that eventually flow into the Yangtze River basin, contributing to the protection of downstream aquatic ecosystems and water quality in the region.
Environmental context
The plant discharges into local rivers that are part of the Yangtze River basin, one of China's most ecologically and economically significant watersheds. The receiving waters support diverse aquatic life and are used for irrigation, industry, and drinking water downstream. Proper treatment is critical to prevent eutrophication and protect biodiversity in this densely populated region.
