パイプで連結すればよい。The triangular weirs 17 formed on the upper ends of the overflow plates 18, 23 and 28 are, for example, 6 to 10 isosceles triangle-shaped ones as shown in FIG.
At the height from the upper end of the overflow plates 18, 23, 28 and the discharge port of the transfer pipe 30 to the water surface, bubbles are often generated,
It is determined by an experiment or the like so that conditions such as water splashing, no water noise, and good water agitation are satisfied. Further, although the above-mentioned active filtration device 1 is integrated with the water tank 2, it may be separated from the water tank 2, and in that case, the water inlet 14 and the upper part of the first filtration chamber 8 of the filtration device 1 will be used. It suffices to connect and with a pipe as appropriate.

による自浄作用も加わり水の汚れ成分が除去される。In the active circulation type water tank equipped with the above-described active filtration device, when the pumping pump 29 is driven, the water in the pumping pump chamber 11 is pumped up and transferred into the tank 2 by the transfer pipe 30. (At this time, if it is dropped from above the water surface of the water tank 2, air is mixed in here as well). The water in the water tank 2 flows through the water inflow port 14 above the first filtration chamber 8 in the active filtration device, then flows down in the first filtration chamber 8 and passes through the coarse filtration material 15 to be caused by microorganisms. The self-cleaning action is also added, and the dirt component of water is removed.

It passes through the triangular weir 17 and flows down to the second filtration chamber 9. At this time, as shown in FIG. 4, the water flow has its tip narrowed by the triangular weir 17, and falls into the water in the second filtration chamber 9 located downstream while entraining air, producing fine bubbles in the water. In this way, water containing air flows down from inside the second filtration chamber 9 from above.
By passing through the fine filter material 21, a self-cleaning action by microorganisms is added, and the dirt component of water is further removed.

It passes through the triangular weir 17 formed in 1 and flows down to the 3rd filtration chamber 10. Here again, as shown in FIG. 4, the water flow whose tip is narrowed by the triangular weir 17 falls into the water in the downstream third filtration chamber 10 while entraining the air and produces fine bubbles in the water, increasing the air in the water.

After going up the third ascending flow path 27 from below the filter material 26 through the gap 25 and becoming equal to the water surface in the third filtration chamber 10, the triangular weir 17 formed on the overflow plate 28 is moved in the same manner as above. It passes and flows down to the pumping pump chamber 11. Here again, as shown in FIG. 4, the water flow whose tip is narrowed by the triangular weir 17 falls into the water in the downstream pumping pump chamber 11 while entraining the air to generate fine bubbles in the water, further increasing the air in the water. Let As described above, the water with increased in-water air is supplied into the water tank 2 by the pumping pump 29 through the transfer pipe 30 as described above, and the water in the water tank is stirred and activated, and at the same time, the water in the filter medium is Self-cleaning action by microorganisms in water is also actively performed.

成分が除去される。In the active circulation type water tank equipped with the filtering device of the second example configured as described above, if the pumping pump 29 is driven, the water in the pumping pump chamber 11 is pumped up and transferred as in the first example. Water is fed into the water tank 2 through the pipe 30 (at this time, if the water is dropped from above the water surface of the water tank 2, air is mixed therein). After the water in the water tank 2 flows from the water inflow port 14 ′ to below the first filtration chamber 8 ′ in the active filtration device,
By ascending in the first filtration chamber 8'and passing through the coarse filtration material 15, the self-cleaning action by microorganisms is also added and the dirt component of water is removed.

故省略する。The water that has risen above the coarse filtration material 15 passes through the triangular weir 17 formed in the overflow plate 18 and flows down into the second filtration chamber 9. At this time, as shown in FIG. 4, the water flow is 1
The tip is narrowed by 7 and falls into the water in the second filtration chamber 9 at the downstream while entraining air, and fine bubbles are generated in the water. In this way, the water containing air can be supplied to the second filtration chamber 9
By flowing down in the chamber 9 from the upper side and passing through the fine filter material 21, a self-cleaning action by microorganisms is added, and the dirt component of water is further removed. It should be noted that the following steps are omitted because they are similar to the first example.

As disclosed in Japanese Patent Laid-Open No. 4 publication, dirt is removed from the inside of the water tank by a filtration device attached to the water tank, and air is sent using an air pump or an air lift in order to supply oxygen to the water tank. I'm out. By the way, in the case of freshwater fish among the above-mentioned ornamental fish, in order to make them live healthy in the aquarium, the hydrogen ion index of water, that is, P-Hit (hereinafter referred to as PH), is ideally 7.0 or more. Is 7.2
Must be maintained at ~ 7.5. However, in the conventional one, since a large amount of air is continuously sent to the water in the water tank for a long period of time by using the air pump or the air lift, oxygen becomes excessive, so that P. H is the standard value 7.0
The water became cloudy as described below, and the ornamental fish and the like had problems such as damage to fins and eyes and eventually death. On the other hand, in clear streams in the mountains, when water flows down, large and small heads,
Due to the mixed flow of air, air is mixed properly in the water,
The excess oxygen does not occur as described above.

パイプで連結すればよい。The triangular weirs 17 formed on the upper ends of the overflow plates 18, 23 and 28 are, for example, 6 to 10 isosceles triangle-shaped ones as shown in FIG.
At the height from the upper end of the overflow plates 18, 23, 28 and the discharge port of the transfer pipe 30 to the water surface, bubbles are often generated,
It is determined by an experiment or the like so that conditions such as water splashing, no water noise, and good water agitation are satisfied. Further, although the above-mentioned active filtration device 1 is integrated with the water tank 2, it may be separated from the water tank 2, and in that case, the water inlet 14 and the upper part of the first filtration chamber 8 of the filtration device 1 will be used. It suffices to connect and with a pipe as appropriate.

(At this time, if it is dropped from above the water surface of the water tank 2, air is mixed in here as well). The water in the water tank 2 flows through the water inflow port 14 above the first filtration chamber 8 in the active filtration device, then flows down in the first filtration chamber 8 and passes through the coarse filtration material 15 to be caused by microorganisms. The self-cleaning action is also added, and the dirt component of water is removed.

It passes through the triangular weir 17 and flows down to the second filtration chamber 9. At this time, as shown in FIG. 4, the water flow has its tip narrowed by the triangular weir 17, and falls into the water in the second filtration chamber 9 located downstream while entraining air, producing fine bubbles in the water. In this way, water containing air flows down from inside the second filtration chamber 9 from above.
By passing through the fine filter material 21, a self-cleaning action by microorganisms is added, and the dirt component of water is further removed.
