Abstract: A marine information integrated online monitoring buoy system comprises a buoy body. Specifically, a protection apparatus is disposed outside the buoy body. A bearing is disposed outside the buoy body, convex strips are arranged around a bearing outer ring, two floating rings are disposed outside the bearing outer ring with a certain spacing distance from the outer ring and arranged vertically, a protective cylinder is arranged between the upper and lower floating rings in a surrounding manner and is rotatable relative to the floating rings, and then a protective retaining ring is sleeved outside the protective cylinder and is rotatable relative to the protective cylinder. The longest end of a protective retainer is abutted against the bearing outer ring during rotation of the outer side of the protective retaining ring, and a friction block is disposed on the protective retainer.

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.

Abstract: Provided is a method for disposing of contaminated deposit soil and recycled reclamation soil using the same and, more specifically, a method for disposing of contaminated dredged soil, the method comprising the steps of: seeding a mixed strain NIX51 (KACC81038BP) in the contaminated dredged soil to primarily dispose of contaminated materials in a bioreactor; and washing the degraded soil, which has been primarily disposed of, with a washing solution containing at least one selected from the group consisting of citric acid, oxalate, carbonic acid (H2CO3), and nitric acid, to secondarily dispose of heavy metals.

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 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: A live seafood storage apparatus having a tank for holding seafood, such as lobsters, and a substantially rectangular storage tank for a large quantity of bacteria-supporting bio-media. The storage tank is disposed beneath the lobster tank. Normally, water drains from the lobster tank into the storage tank, where it passes through a pre-filter and down through the large volume of bio-media. Water is moved from the storage tank back to the lobster tank by a pump. If a power failure occurs, substantially all of the water drains from the lobster tank by gravity into the storage tank. Closed access doors minimize evaporation, thus providing sufficient moisture within the lobster tank for lobsters to survive for an extended period of time.
