Abstract:

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.
