摘　　要：采用50 kHz超声去除水华鱼腥藻,研究了藻类初始浓度、溶液体积对处理过程的影响.结果表明,在超声过程中藻类浓度随超声时间延长逐渐降低.而随着藻类初始浓度和处理体积的增加,去除速率亦逐渐下降.此外,研究了纯水超声过程中H2O2的生成动力学,探讨了超声去除藻类的机理.The removal of Anabaena flos-aquae by 50 kHz ultrasound was studied in this paper. The effect of initial concentrations and solution volumes of the algae exposed to ultrasound was investigated. The results showed that the reduction rate of the algae was in accordance with pseudo-first-order equation. The removal rate of the algae decreased with increasing initial concentrations and volumes exposed to ultrasound. The formation rate of H2O2 during sonolysis of H2O was also studied. Finally,the mechanism of removal of algae by ultrasound was proposed.
