| 摘要 |
The present invention provides a ballast water treatment system, comprising a centrifugal separator, an ultrasonic sterilizer, and an ultraviolet sterilizer, wherein, the centrifugal separator is designed to separate large-particle of foreign matters from the ballast water by centrifugal separation by means of density difference; the ultrasonic sterilizer is arranged at the back of the centrifugal separator, and is designed to accomplish ultrasonic sterilization for the ballast water passing through the centrifugal separator; the ultrasonic sterilizer comprises a pipe that is used for sterilization of the ballast water and ultrasonic irradiation unit that perform ultrasonic irradiation for the ballast water passing through the pipe; the ultraviolet sterilizer accomplishes sterilization by means of ultraviolet irradiation for the ballast water passing through the ultrasonic sterilizer. The ballast water treatment system provided in the present invention can effectively accomplish sterilization for the ballast water that flows into the ballast tank of ship, and thereby prevent all kinds of pollution to seawater related with ballast water discharge, and greatly improve reliability of application. |
