Abstract：
 The present invention relates to method and system for eliminating phycotoxin from water works and secondary water tower. Ultrasonic radiator and ultraviolet radiator are set inside water to be treated for ultrasonic radiation and ultraviolet radiation, the ultrasonic radiation has frequency of 20-150 KHz, strength of 30-5000 W/sq m and time of 5-20 min, and the ultraviolet radiation adopts ultraviolet rays in B section or C section, and has power of 0.1-20 W/sq m and time of 0.1-2 min. The said process can eliminate phycotoxin from water in high efficiency at normal temperature and pressure without secondary pollution while generating sterilizing and algae killing effects.
