摘要:
针对富营养化水体中的藻污染问题,利用超声波在水中的机械效应和空化效应产生的高压、冲击波、声流和剪切等力学作用,研究不同超声频率、超声功率、超声时间对铜绿微囊藻的去除影响.结果表明,当超声频率为500 kHz,超声功率为80 W时,藻类的去除效果最好,超声5 min后,除藻率可达到94%,而且通过二次超声可进一步抑制残余藻类的生长,稳定除藻效果.最后,采用FDA-PI双色荧光法观察和识别经超声处理后藻细胞的存活形态和结构变化,研究超声除藻的作用机理.
Abstract:
The removal efficiency of Microcystis aeruginosa by the mechanical effects,which was caused by ultrasonic cavitations,such as high pressure,shock wave,acoustic streaming and shear force,was studied.The efficiency of algal removal can be reached to 94% at the optimum conditions: 80 W ultrasonic power,500 kHz ultrasonic frequency,and 5 minutes for ultrasonic duration.The efficiency of algal removal can be stabilized by the secondary ultrasonic processing.Furthermore the mechanisam of algal removal by ultrasonic was investigated by the fluorescent method called FDA-PI(fluorescein diacetste and propidium iodide).
