Overview
Guizhou wastewater treatment plant serves Yunyan District, Guiyang, China, with a population of 120,000. It operates under China's national wastewater standards for urban agglomerations.
The Guizhou wastewater treatment plant is located in Yunyan District, Guiyang, Guizhou Province, China. It serves a population of approximately 120,000, classifying it as a medium-to-large urban agglomeration under Chinese wastewater management frameworks. The plant is situated in a densely populated urban area within the Guiyang metropolitan region. As a facility serving over 100,000 people, the plant is expected to meet 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. Typical plants of this scale in China employ activated sludge processes with biological nutrient removal to comply with national effluent standards. The plant discharges treated wastewater into the local water system, which ultimately drains into the Yangtze River basin via the Wu River system. The receiving water body supports downstream aquatic ecosystems and is used for agricultural and industrial purposes. Effective treatment is critical to prevent eutrophication and protect water quality in the region.
Environmental context
The plant's treated effluent flows into the Wu River, a tributary of the Yangtze River, which eventually reaches the East China Sea. The watershed supports diverse aquatic life and is an important resource for irrigation and industry. Nutrient pollution from urban wastewater poses a risk of eutrophication in downstream lakes and reservoirs, making advanced treatment essential for ecological health.
