Abstract

This study comprehensively applies ultrasonic, sonosensitizers, and cationic starch methods aimed at improving the treatment effects on Microcystis aeruginosa cells and particulates in water bodies. The experimental results show that the rupture and mortality of Microcystis aeruginosa cells are significantly increased through the high temperatures, high pressures, and intense liquid motion produced by ultrasonic vibration and the collapse of tiny bubbles. The auxiliary role of sonosensitizers enhances the ultrasonic effects, while cationic starch as a flocculant facilitates the aggregation of Microcystis aeruginosa cells and particulates into larger clumps, easing subsequent processing and removal. Under experimental conditions, this method successfully enhanced the rupture and mortality of Microcystis aeruginosa cells, achieving a significant removal efficiency of pollutants at 89.7%.
