Overview
Guizhou wastewater treatment plant serves Guiyang, China, with a population equivalent of 125,000. It operates under China's national wastewater discharge standards.
The Guizhou wastewater treatment plant is located in Qingzhen, Guiyang, Guizhou Province, China. It serves a population equivalent of 125,000, classifying it as a medium-to-large agglomeration under Chinese regulatory frameworks. The plant is situated in an inland urban area, contributing to the region's water management infrastructure. As a facility of this scale in China, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment as a baseline and may require advanced treatment for discharge into sensitive water bodies. Typical plants of this size employ activated sludge or similar biological processes. The plant discharges into local water bodies that ultimately drain into the Yangtze River basin via the Wu River system. This watershed supports diverse aquatic life and provides water for agriculture and urban use downstream. Effective treatment is critical to prevent eutrophication and protect downstream ecosystems.
Environmental context
The plant's treated effluent likely enters the local river network, which flows into the Wu River, a tributary of the Yangtze River. The Yangtze basin is ecologically significant, supporting numerous fish species and providing water for millions of people. Discharge from this plant must meet strict nutrient limits to avoid contributing to algal blooms in downstream lakes and reservoirs.
Frequently asked questions
The plant is located at Binhu Road, Qingzhen, Guiyang, Guizhou Province, China.
The plant serves a population equivalent of 125,000 people.
The plant protects local rivers that flow into the Wu River, a tributary of the Yangtze River, by treating wastewater before discharge.
The plant operates under China's GB 18918-2002 standard, which sets discharge limits for pollutants. For a plant of this scale, secondary treatment is required, with possible tertiary treatment for sensitive areas.
Plants of this size in China commonly use activated sludge processes with nutrient removal to meet national discharge standards, especially if discharging into ecologically sensitive water bodies.
