Overview
Guizhou wastewater treatment plant serves 200,000 people in Xinhua Subdistrict, Duyun, Guizhou, China. It operates under national standards for municipal wastewater treatment.
The Guizhou wastewater treatment plant is located in Xinhua Subdistrict, Duyun City, Guizhou Province, China. It serves a population of approximately 200,000, classifying it as a large agglomeration under Chinese wastewater management standards. As a municipal facility in China, the plant is expected to comply with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. For large agglomerations, secondary treatment with nutrient removal is typically required to protect water quality. The plant's treated effluent likely discharges into a local river within the Yangtze River basin or the Pearl River basin, as Guizhou is a headwater region for several major rivers. The plant plays a key role in protecting downstream aquatic ecosystems and water resources in southern China.
Environmental context
The plant is located in Guizhou Province, a karst region with numerous rivers and high ecological sensitivity. Treated wastewater likely enters a tributary of the Wu River or the Hongshui River, which eventually flow into the Yangtze River or Pearl River basins. These waters support diverse aquatic life and provide drinking water for millions downstream. Proper treatment is critical to prevent eutrophication and protect karst groundwater systems.
