Ultraviolet and ultrasonic-wave combined treatment reactor

The utility model belongs to the field of water treatment equipment and particularly relates to an ultraviolet and ultrasonic-wave combined treatment reactor. The reactor mainly comprises an ultraviolet treatment system and an ultrasonic-wave treatment system. Ultraviolet radiation emitted by the ultraviolet treatment system has good killing effects on individual small bacteria and pathogens. The mechanical and cavitation effects of the ultrasonic-wave treatment system can effectively eliminate large microorganisms in treated media, simultaneously the ultrasonic-wave treatment system can have cleaning effects on the ultraviolet treatment system, penetrability of ultraviolet light is improved, and accordingly sterilization inactivation efficiency of the whole system is improved. The ultraviolet and ultrasonic-wave combined treatment reactor is high in automation, compact in structure, stable in work, high in sterilization efficiency and good in effect when used for sterilization of ballast water.
