Overview
Guizhou wastewater treatment plant serves 760,000 people in Nanming District, Guiyang, China. It operates under China's national wastewater standards for large urban agglomerations.
The Guizhou wastewater treatment plant is located in Nanming District, Guiyang, Guizhou Province, China. It serves a population of 760,000, classifying it as a large urban agglomeration under Chinese wastewater management frameworks. As a major facility in Guiyang, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for large-scale plants. For agglomerations of this size, advanced treatment (Class 1A or 1B) is typically required to protect receiving waters. The plant discharges into the local watershed, which ultimately drains into the Yangtze River basin via the Wu River system. This downstream connection makes the plant's performance critical for water quality in the Yangtze River ecosystem, supporting aquatic biodiversity and downstream water uses.
Environmental context
The plant's treated effluent enters the local water network within the Wu River sub-basin, a tributary of the Yangtze River. The Yangtze River basin is one of the world's most biodiverse freshwater ecosystems, supporting numerous fish species and migratory birds. Effective treatment at this scale helps reduce nutrient loading and protect downstream water quality in this ecologically significant river system.
Frequently asked questions
The plant is located in Nanming District, Guiyang, Guizhou Province, China.
The plant serves approximately 760,000 people, making it a large urban agglomeration.
The plant discharges treated effluent into the local watershed, which flows into the Wu River and eventually the Yangtze River.
The plant operates under China's GB 18918-2002 standard, which sets effluent limits for municipal wastewater treatment plants. Large agglomerations like this typically require advanced treatment to meet Class 1A or 1B standards.
For large urban agglomerations in China, advanced biological treatment with nutrient removal is standard, often including secondary treatment followed by tertiary processes to meet stringent effluent limits.
