Overview
Guizhou wastewater treatment plant serves Nanming District, Guiyang, Guizhou, China, with a population equivalent of 105,000. It operates under China's national wastewater standards.
The Guizhou wastewater treatment plant is located in Nanming District, Guiyang, Guizhou Province, China. It serves a population equivalent of 105,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management. 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 and nutrients. For plants of this scale, secondary treatment with nutrient removal is typically required, especially in sensitive watersheds. The plant discharges into the local water system within the Yangtze River basin, ultimately draining into the East China Sea. Its operation is critical for protecting downstream aquatic ecosystems and maintaining water quality in the densely populated Guiyang region.
Environmental context
The plant discharges into the local water network within the Yangtze River basin, which flows through central China before reaching the East China Sea.
