超声波技术抑藻效果的研究

Studies on the Inhibition of Algal Growth by Ultrasonic Radiation Technology

为探明超声波的抑藻效果,本研究利用超声波技术对富营养化水体中藻类进行抑制研究。结果表明,超声波能够有效地抑制水中藻类数量的增加,对水中藻类的组成和优势物种不产生明显作用;尤其对蓝藻和硅藻数量具有显著的抑制效果,其抑藻效果在使用超声波1个月后表现最良好,但对绿藻生长的抑制作用表现不明显。说明超声波虽然能在一定程度上抑制藻类的增加,但对改善水质的效果不明显。

To explore the effect of the ultrasonic radiation can inhibit the increase of the algae,in this study,ultrasonic radiation technology was used to inhibit algae ＇ s growth in the eutrophication water.The results showed that the ultrasonic radiation effectively inhibited the increase in the number of algae,but no significant influence on the composition and dominant species of algae.Cyanobacteria and Bacillariophyta in particular,a significant number of the inhibitory effect,its inhibitory effect on the performance of the most one month after using ultrasonic radiation,but no significant influence on Chlorophyta.The results also showed that the ultrasonic radiation inhibited the increase of the algae to some extent,but little effect on improving water quality.
