For example, if the liquid to be filtered is bath water used in a bath, and it is desired to filter turbid substances in the bath water,
Assumed removal substances are oils and fats, sebum cells, etc. (normally,
The size is 5 to 60 μm), and bacteria having different properties (usually 0.3 to 3 μm in size) and large hair are excluded. In the case where the assumed removal substance is a turbid substance, a hole larger than 90% particle diameter of the turbid substance is formed in the filter, whereby a turbid substance or a suspension such as hair larger than the turbid substance is filtered. . In the multilayer filter of the present invention, the degree of distribution of the overlapping openings (filtration holes) changes depending on the number and distribution of through holes formed in the filter, and the filtration performance is slightly affected by the properties of the liquid to be treated. Therefore, when the distribution of the assumed removal substance is unusually spread to the smaller diameter side, it is effective in some cases to reduce the pore diameter to a particle diameter near the representative value.

What should be the diameter of this hole,
Explaining with a specific example, when the liquid to be treated is bath water, the 90% particle size is 30 to 50 μm. As described above, the assumed removal substance is a turbid substance in the bath water and does not filter bacteria. Assuming that a sufficient number of the through holes are evenly distributed, the diameter of the through hole of the filter is preferably about 300 to 700 μm, which is one order larger than the 90% particle size. When the liquid to be treated is tap water, the 90% particle size is 5 to 10 μm, and at this time, the through-hole diameter of the filter is preferably 50 to 100 μm. Further, in the case where the liquid to be treated is tap water stored and hypochlorous acid is removed, the supposedly removed substance becomes a bacterium, and the 90% particle size becomes 3 μm. At this time, the diameter of the through hole of the filter is 20 to
It is preferable to adopt 50 μm.

As shown in FIG. 7, at the time of regeneration, a gap h larger than at least the suspension is provided between the respective filter bodies 2 by the spring 5 (not shown). As a result, the suspended matter trapped in the through-hole 2b is in a free state without any restraint, and in this state, by flowing a washing solution or the like, the suspended matter is filtered from the through-hole 2b from the through-hole 2b. It easily exits toward the gap between the filters, flows out of the multilayer filter 3, and is discharged from the inflow port 1a to the outside of the processing tank 1. In this way,
The suspended matter is discharged very efficiently, and the laminated filter 3 is regenerated.

When the motor 7 is driven during the regeneration process to move the upper holding plate 6 up and down, the filter 2 is also moved up and down by the spring 5. As a result, water flows in the direction of the hole axis of the through-hole 2b, whereby the suspended matter easily comes out of the through-hole 2b toward the gap between the filter bodies 2.

On the other hand, there is only a slight shift (about 1 to 2 mm).

(Embodiment 11) Embodiment 11 is different from Embodiments 1 to 10 in that there are two types of filter bodies 2 having different specific gravities, which are alternately laminated. Further, the specific gravity of the two types of filter bodies 2 is such that one is heavier than the specific gravity of the liquid during regeneration and the other is lighter. Thereby, if the regenerating water is allowed to flow in the state where there is a gap between the filter bodies 2 at the time of regeneration, one filter body 2 sinks and one filter body 2 floats. Therefore, the size of the gap between the respective filter bodies 2 at the time of regeneration is different, so that the flow of the regeneration water is disturbed, thereby causing the filter body 2 to vibrate slightly. When the filter body 2 causes micro-vibration, the object to be filtered (suspension) in the through hole 2b easily comes out of the through hole 2b, and the regeneration efficiency of the laminated filter 3 is improved. .

(Embodiment 12) Embodiment 12 is different from Embodiments 1 to 11 in that at least one spring 5 having a different spring pitch is provided. Thereby, each filter body 2 is in a state of being inclined with respect to the lamination plane at the time of regeneration. FIG. 49 is a partially enlarged perspective view showing a state where the filter body 2 has an inclination during regeneration. As shown in FIG. 49, when the regenerated water flows in a state where the filter body 2 is inclined, the regenerated water flows into the through-hole 2b, and the object to be filtered (suspension) existing in the through-hole 2b is outside the through-hole 2b. Therefore, the regeneration rate of the multilayer filter 3 is improved.

(Thirteenth Embodiment) A thirteenth embodiment differs from the first to twelfth embodiments in that at least one spring 5 having a different spring constant is provided. If the regenerated water is allowed to flow in the state where there is a gap between the respective filters during regeneration, the force that each filter 2 receives due to the flow of the regenerated water is transmitted to each spring. At this time, each spring vibrates slightly with the force received from the filter body 2. Here, if the springs have different spring constants, the respective springs will cause different minute vibrations. As a result, each filter body 2 causes complicated micro-vibration in the laminating direction, whereby the material to be filtered (suspension) in the through-hole 2b is easily discharged out of the through-hole 2b, and the lamination is performed. The regeneration rate of the filter 3 is improved.
