Overview
Guizhou wastewater treatment plant serves Jinsha County in Guizhou Province, China, with a population of 62,000. It operates under China's national wastewater regulations.
The Guizhou wastewater treatment plant is located in Jinsha County, Guizhou Province, China, serving an estimated population of 62,000. The facility is situated in the urban area of Guchang Street, within the broader Bijie City region. As a municipal plant, it plays a key role in managing domestic wastewater for this inland community. China's wastewater treatment standards are governed by the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For plants serving populations around 62,000, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B effluent standards, depending on the receiving water's sensitivity. It is expected to comply with these national norms. The plant discharges treated effluent into local water bodies that ultimately drain into the Yangtze River basin via the Wu River system. The surrounding region is characterized by karst topography and agricultural land use, making proper nutrient management critical to prevent eutrophication in downstream lakes and reservoirs. The plant's operation supports both public health and the ecological integrity of the Guizhou watershed.
Environmental context
The plant's treated effluent flows into local streams that are part of the Wu River system, a tributary of the Yangtze River. The downstream environment includes ecologically sensitive karst wetlands and reservoirs that support diverse aquatic life. Nutrient loading from wastewater can contribute to algal blooms in these water bodies, so effective treatment is essential for maintaining water quality in the Yangtze basin.
