Overview
The Guizhou wastewater treatment plant serves Zhongshan District, Liupanshui, Guizhou, China, with a population equivalent of 89,000. It operates under China's national wastewater discharge standards.
The Guizhou wastewater treatment plant is located in Zhongshan District, Liupanshui City, Guizhou Province, China. It serves a population of approximately 89,000 people, placing it in the medium agglomeration category for Chinese municipal wastewater infrastructure. As a plant in China, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and heavy metals. For plants of this scale, secondary treatment with nutrient removal is typically required, especially in sensitive watersheds. The plant's treated effluent is discharged into local water bodies within the Yangtze River basin, ultimately flowing into the East China Sea. The surrounding region is characterized by karst topography and mountainous terrain, making water quality protection critical for downstream ecosystems and drinking water sources.
Environmental context
The plant discharges into tributaries of the Yangtze River basin, which flows through central China before reaching the East China Sea. The local watershed supports diverse aquatic life and provides water for agriculture and industry. Given the karst geology of Guizhou, groundwater protection is particularly important, as pollutants can quickly infiltrate underground water systems.
