摘要
超声波控藻技术具有设备简单、经济性好、无二次污染及管理方便等优点,具有很大的发展潜力和广阔的应用前景。综述了超声波控藻技术的基本原理、控藻效果影响因素、超声波对水生态的影响及超声波与其他技术联用的控藻效果。采用超声波技术控藻时,超声波强度越大,耗能就越高,经济性也越差,且超声波强度过高会抑制水生生物的生长;从控藻效果、安全性和经济性等方面综合考虑,低强度超声波更适用于蓝藻水华控制。超声波与其他控藻技术联用可以提高控藻效率,低强度超声波与其他技术联用将是今后超声波控藻技术发展的方向。
Ultrasonic algae control technology has great development potential and broad application prospects with the advantages of simple equipment,economical efficiency,without secondary pollution and simple management.The basic principles of ultrasonic algae control technology,the factors affecting the efficiency of algae control by ultrasound,the impact of ultrasound on water ecological environment and the algae removal efficiency of ultrasound technology combined with other technologies were reviewed.The results showed that in the case of ultrasonic algae control,the higher the intensity,the greater the energy consumption and the more the cost.Moreover,the excessive power could inhibit the growth of aquatic organisms.Considering the removal efficiency,safety and economy of algae control,the low-power ultrasonic technology was more suitable for cyanobacterial bloom control.At the same time,the combination of ultrasound and other algae control technologies could improve the efficiency of algae removal,which would be a development direction of ultrasonic control algae technology in the future.
