Overview
Guizhou wastewater treatment plant serves 120,600 people in Baiyun District, Guiyang, Guizhou Province, China. It operates under China's national wastewater discharge standards.
The Guizhou wastewater treatment plant is located in Baiyun District, Guiyang, the capital of Guizhou Province in southwestern China. It serves a population of 120,600, placing it in the medium-to-large agglomeration category for Chinese municipal wastewater infrastructure. As a plant serving over 100,000 people, it is subject to China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive water bodies. Facilities of this scale typically employ activated sludge processes with biological nitrogen and phosphorus removal. The plant discharges into the local watershed, which ultimately drains into the Wu River system, a tributary of the Yangtze River. This positions the plant as a key facility for protecting downstream water quality in the Yangtze River Basin, one of China's most ecologically and economically significant river systems.
Environmental context
The plant is located in the Wu River sub-basin of the Yangtze River Basin. Treated effluent flows into local waterways that feed the Wu River, which joins the Yangtze River downstream. The Yangtze River supports diverse aquatic life and provides drinking water for millions. Effective treatment at this plant helps reduce nutrient loading and protects the ecological health of the Yangtze River system.
