Overview
Guizhou wastewater treatment plant serves 210,000 people in Huichuan District, Zunyi, Guizhou, China. It operates under China's national wastewater standards for urban agglomerations.
The Guizhou wastewater treatment plant is located in Huichuan District, Zunyi, Guizhou Province, China. Serving a population of 210,000, it is classified as a large agglomeration under Chinese wastewater regulations, which mandate advanced treatment for cities of this scale to protect water quality. As a facility in China, the plant 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 large agglomerations, tertiary treatment is typically required, especially in sensitive watersheds. Regulatory compliance ensures appropriate treatment levels. The plant discharges treated effluent into the local watershed, which ultimately drains into the Yangtze River basin via the Wu River system. This downstream water body supports diverse aquatic life and provides water for agricultural and industrial use. Proper treatment is critical to prevent eutrophication and protect downstream ecosystems.
Environmental context
The plant's treated effluent flows into the Wu River, a tributary of the Yangtze River, which is one of China's most important water bodies. The Yangtze basin supports a vast array of aquatic species and provides drinking water for millions. Nutrient removal is essential to avoid algal blooms and maintain ecological balance in this sensitive river system.
