The invention belongs to the technical field of water treatment, and discloses an n-shaped ultrasonic negative pressure disinfection system for ship ballast water, which is communicated with the interior of a ship ballast tank and comprises a discharge pipeline, the discharge pipeline comprises a first bottom-layer pipeline, a high-layer pipeline and a second bottom-layer pipeline; the ballast water conveying device is arranged on the first bottom layer pipeline; the ultrasonic device is arranged on the high-layer pipeline; the controller is connected with the ultrasonic device through a connecting line, and meanwhile, the controller is connected with the ballast water conveying device through a connecting line. The ballast tank is communicated with the long discharge pipeline, pressure difference is generated in the high-layer pipeline, a negative pressure environment is formed, in this way, a large number of bubbles can be generated when ballast water passes through the high-layer pipeline, the bubbles can generate a cavitation effect when meeting ultrasonic waves, cell walls, cell membranes and structures of microorganisms can be physically damaged, and therefore the microbiological effect is improved. The damage or death of microorganisms is caused.
本发明属于水处理技术领域,公开了一种船舶压载水几字形超声波负压消毒系统,连通在船舶压载舱内,包括:整体呈几字形的排出管路;所述排出管路包括第一底层管路、高层管路和第二底层管路;装设于所述第一底层管路上的压载水输送装置;装设于所述高层管路上的超声波装置;与所述超声波装置通过连接线连接的控制器,同时,所述控制器通过连接线连接所述压载水输送装置。本发明中的压载舱连通有一长度较长的排出管路,在高层管路的内部产生压差,形成一个负压环境,这样压载水在经过高层管路的时候会产生大量的气泡,气泡遇到超声波会产生空化效果,会在物理上破坏微生物的细胞壁、细胞膜和结构,导致微生物的破坏或死亡。
