Abstract: The present invention provides a dehydrogenation tank. An atomization spray is disposed at the center of the upper part of the dehydrogenation tank, and flow stirring modules used for stirring a flowing solution are respectively disposed at the middle and the bottom of the dehydrogenation tank. Each of the two flow stirring modules includes at least two layers of flow stirring meshes. By means of disposing the atomizing spray and the flow stirring modules in the dehydrogenation tank, the TRO solution flowing into the dehydrogenation tank are fully stirred, so that hydrogen gas mixed with the TRO solution is able to diffuse out fully and rapidly, thereby increasing dehydrogenation efficiency as well as reducing volume of the dehydrogenation tank. In addition, the present invention also provides a ballast water treatment system having the dehydrogenation tank.

Abstract: An online antifouling ship ballast water treatment system includes a ballast water main pipeline, a ballast water branch pipeline, a dispensing pipeline, a filter on the ballast water main pipeline, an electrolysis unit on the ballast water branch pipeline, and a dispensing pump on the dispensing pipeline. Some of seawater introduced into the system is filtered by the filter and flows to the ballast water branch pipeline and the electrolysis unit, some of seawater electrolyzed by the electrolysis unit is reinjected to the filter through the dispensing pump and the dispensing pipeline after a ballast process is completed, and kept in the filter until a next ballast operation, so that growth and propagation of marine organisms in the filter can be inhibited by sodium hypochlorite contained in a TRO solution when a ballast pump stops working. The present invention also provides a ship ballast water treatment method.

Abstract: The present invention discloses a cleaning liquid for a ship ballast water treatment filter, an online cleaning device and an online cleaning method. The online cleaning device comprises a filter cleaning pipeline and a cleaning liquid preparation tank located in the filter cleaning pipeline. The cleaning liquid preparation tank is provided with a cleaning liquid outlet and a cleaning liquid reinjection opening. The filter cleaning pipeline comprises a cleaning liquid injection pipeline located between the cleaning liquid outlet of the cleaning liquid preparation tank and a filter water inlet, and a cleaning liquid reinjection pipeline located between a filter water outlet and a cleaning liquid reinjection opening of the cleaning liquid preparation tank. The cleaning liquid prepared in the cleaning liquid preparation tank is injected into the filter through the cleaning liquid injection pipeline and is re-injected into the cleaning liquid preparation tank through the cleaning liquid reinjection pipeline.
