Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an algae-dissipating ship that efficiently dissipates algae, such as red sea tides and red tides, generated in lakes and marine areas at an early stage of development.
[0002]
[Prior art]
Conventional methods for killing algae such as sea cucumbers and red tides include algae killing by algal cell destruction by the strong oxidizing power of ozone, algae killing by gene mutation and growth inhibition by ultraviolet irradiation, and bactericides. Algae killing method by the addition of is put into practical use. And about the process in algae generation | occurrence | production location, the algae killing apparatus is towed by the ship and implemented. In addition, as a dedicated ship with an algae-killing device installed directly on the ship, a floating separation device and an ozone water production device are installed in a purification ship that opens to the front and below the water system, and pressurized water is injected into the inflowing water. A water purification vessel dedicated to concentrating and recovering and injecting ozone into the outflowing water to kill plankton is known, for example, as described in JP-A-9-118291.
[0003]
[Problems to be solved by the invention]
Conventional algae killing method by UV irradiation affects DNA base and prevents replication, but there is a difference in effect depending on the transparency of the target water, and the algae may recover with visible light, so it is uncertain It was a simple method. In addition, although the algicide method by adding a chemical can obtain a certain algicidal effect, there is a fear of the influence on the marine resources due to the residue, and it cannot be said to be a good algicide method from the viewpoint of running cost. Moreover, the algaecidal method using ozone is a good algaecidal method that has a definite effect in a short time by directly destroying algal cell membranes and nucleic acids, etc., and has no effect on fishery resources. A conventional water purification ship equipped with a levitation separator and ozone water production system is affected by the ship's self-propelled speed, tidal current speed, or tidal current direction, and its processing amount varies greatly and becomes unstable. There was a case. And when trying to suck in water for treatment irrespective of self-propelled, it was necessary to provide large capacity pump equipment for sucking up water for treatment. Moreover, the algae to be captured are to be collected by a boat, and the collected algae must be treated. An object of the present invention is to provide an algae extinguishing ship that uses a jet propulsion device as a device for sucking algae into a boat and kills algae with ozone.
