Overview
Guizhou wastewater treatment plant serves Tongren City in Guizhou Province, China, with a population equivalent of 135,000. It operates under China's national wastewater discharge standards.
The Guizhou wastewater treatment plant is located in Tongren City, Bijiang District, Guizhou Province, China. It serves a population of approximately 135,000 people, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The facility is situated inland, far from coastal areas, and its treated effluent likely discharges into local rivers that are part of the broader Yangtze River basin. As a plant serving over 100,000 people, it is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for facilities of this scale. It is subject to national regulations that require consistent monitoring and compliance with effluent quality standards. The plant's discharge ultimately flows into the Yangtze River system, which is ecologically significant as one of the world's major river basins. The downstream environment supports diverse aquatic life and provides water for agriculture, industry, and domestic use. Proper treatment at this facility helps protect water quality in the region and contributes to the health of the Yangtze River ecosystem.
Environmental context
The plant's treated wastewater likely discharges into a tributary of the Wu River, which flows into the Yangtze River, one of the world's most important freshwater systems. The Yangtze basin supports a wide range of aquatic species, including the critically endangered Yangtze finless porpoise and various migratory fish. Effective wastewater treatment is crucial to prevent eutrophication and maintain water quality in this ecologically sensitive region.
