Overview
Guizhou wastewater treatment plant serves 61,000 people in Ximen Street, Kaili City, Guizhou Province, China. The facility operates under China's national wastewater standards.
The Guizhou wastewater treatment plant is located in Ximen Street, Kaili City, within the Qiandongnan Miao and Dong Autonomous Prefecture of Guizhou Province, China. It serves a population of approximately 61,000 residents, placing it in the medium-scale category for municipal wastewater treatment in the region. As a Chinese wastewater facility, the plant is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for various pollutants. For a plant of this size, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The plant's treated effluent likely discharges into a local waterway within the Yangtze River basin, as Guizhou Province is part of this vast drainage system. The downstream environment includes the Yangtze River and its tributaries, which support diverse aquatic ecosystems and provide water for agriculture, industry, and drinking water for millions of people downstream.
Environmental context
The plant discharges into a local tributary of the Yangtze River basin, which ultimately flows into the East China Sea. The Yangtze River ecosystem supports a wide range of aquatic life, including endangered species such as the Chinese sturgeon and finless porpoise. Effective treatment at this plant helps reduce nutrient and pollutant loads, protecting downstream water quality and biodiversity.
