Definitions
- the present invention relates to a centrifugal solid-liquid separation device that separates microorganisms from a liquid to be treated which is taken as ballast water from a water area where a ship calls, and a water treatment device using the same.
- Ballast water is transported as a “weight” of the ship to the next port of call and discharged with the load. In other words, marine life from the previous port of call will be brought to the next port of call. In this way, moving an organism from one place to another is likely to lead to destruction or contamination of the local ecosystem nurtured by nature. Therefore, the International Maritime Organization (IMO) has adopted the Ballast Water Convention (International Convention for the Control and Management of Ship Ballast Water and Sediment) that sets the standard for the amount of organisms contained in discharged ballast water. .

- the water level L in the lower liquid container 24 rises.
- the water surface after the rise is “L1”.
- the liquid to be processed in the lower liquid container 24 does not flow back into the cyclone 21. This is because the increase in the pressure P22 of the lower liquid port 22c is absorbed by reducing the volume of the space 24s in the lower liquid container 24.

- the liquid to be treated that flows into the cyclones 21 and 22 passes through the inactivation device 10, most aquatic organisms are considered dead. However, large aquatic organisms and the like that are visible can be alive. Therefore, when the to-be-processed liquid which has not been separated is stored in the processed liquid storage tank 30 as the processed liquid, the aquatic organisms are stored in the processed liquid storage tank 30 while the processed liquid is transported as ballast water. If it is propagated at the port and discharged at the next port of call, it may cause environmental pollution.
- the space 24s in the lower liquid container 24 shown in FIGS. 1 and 2A prevents backflow into the cyclones 21 and 22 due to the pressure difference between the lower liquid ports 21c and 22c between the cyclones 21 and 22.

When the valve 25 is opened, aquatic organisms and the like in the lower liquid container 24 are discharged into the storage container 26. When the contents of the lower liquid container 24 are discharged, the valve 25 is closed.
- the flushing pump 27 upstream of the storage container 26 is operated.
- the flushing pump 27 draws up the liquid to be treated outside the ship and causes the high-pressure water to flow toward the downstream side of the storage container 26. Thereby, aquatic organisms and the like in the storage container 26 are discharged from the downstream end 28b to the outside of the ship through the discharge pipe 28.
- the flushing pump 27 may not be provided. This is because aquatic organisms and the like in the storage container 26 can be released out of the boat without using the flushing pump 27.

That is, the lower liquid container 24 has a space forming portion 24x above the communication opening ends 21do and 22do of the pipes 21d and 22d from the cyclones 21 and 22.
- FIG. 4 shows a case where the lower liquid ports 21 c and 22 c of the cyclones 21 and 22 are directly penetrated into the lower liquid container 24. In such a case, it may be said that the lower liquid ports 21c and 22c are the communication opening ends 21do and 22do (see FIG. 3).

- an air vent 44r may be used.
- the hypochlorous acid in a to-be-processed liquid is neutralized by the neutralization apparatus 49 provided in the storage container 46.
- FIG. The aquatic organisms and the like in the storage container 46 are discharged out of the ship from the discharge port 48b together with the liquid to be processed.
- a flushing pump 47 may be used for discharging.
- the liquid to be processed discharged from the liquid outlets 41b and 42b of the cyclones 41 and 42 is sent to the processed liquid storage tank 30 as a processed liquid.
