Abstract:

Water quality pollution events in urban distribution system always show the characteristics as abruptness and variety, and the ability of qualitative detection of water quality contamination events is limited in water quality early warning. Aiming to these, the application of Dempster-Shafer theory in water quality analysis is studied on, and the quantitative detection method of contaminant in drinking water based on water quality parameters is proposed. Combining with experiment and simulation, the analysis results show that the method could weaken the dependence of historical data effectively. Comparing with regular cluster algorithm, the method adjusts local non-linear variation between contaminant concentration and water quality parameters and has better performance.
