超声波技术预防性抑制蓝藻水华的研究

Research on preventive inhibition for cyanobacteria blooms using ultrasound technology

指出传统的蓝藻水华治理方法中存在的问题:大规模地杀灭蓝藻,造成大量藻细胞破裂,细胞内藻毒素等有害分泌物释放到水中,引发二次污染。介绍蓝藻水华的预防性调控方法,即在水体形成水华前,通过抑制蓝藻细胞生长,将其藻类生物量始终控制在一定水平以下,避免蓝藻水华的暴发。综述了超声参数对除藻抑藻效果的影响,以及超声对藻细胞生理系统的影响,探讨超声除藻抑藻的机理,并针对以往研究存在的不足,对后续研究重点进行了展望。

Problems in traditional methods for treating cyanobacteria bloom were pointed out,which is algal cells rupture will happen when killing massive cyanobacteria,and intracellular algal toxins and other harmful secretions are inevitably released to the aquatic environment,leading to the secondary pollution. Therefore,the preventive regulation method for cyanobacterial blooms was proposed in this study. Before cyanobacterial blooms happen,algae biomass was herein controlled under a certain level by inhibiting algae growth. Thus the cyanobacterial blooms were avoided. In addition,the influence of the ultrasonic parameters on the algae removal or inhibition as well as the ultrasound influence on cellular physiological system was analyzed. The mechanism of algae removal and inhibition by the ultrasound was employed. Given the existed deficiencies in previous studies,the focus of follow-up study was prospected.
