2. Description of the Related Art Wastewater from a fish tank for growing seafood contains a large amount of residual food, excrement, carcasses, etc. of the seafood, and a large amount of water is required for its growth (culture). Therefore, for the growth of the seafood, a closed circulation system in which the wastewater is purified / filtered and circulated for use is preferable. However, when this closed circulation system is adopted, it is necessary to use a high-performance water purification / filtration device for the wastewater. As this water purifying / filtering device, various devices have been proposed in the past, and generally, a plurality of types of filter media are used to filter the residual food, excrement, and carcasses of the seafood. In addition, many devices have been proposed in which a microbial membrane is formed on a filter medium, and the waste water is brought into contact with the microbial membrane to purify and filter the water.

However, when using such a water purifying / filtering device, there are the following problems. That is, it is necessary to wash the filter medium regularly, which requires a lot of trouble. In order to improve the filtration performance, it is necessary to use many types of filters having different densities (for example, gravel with different particle diameters) and have a multi-layer structure, which complicates the structure of the device itself. Since the wastewater contains a high concentration of ammonia nitrogen, it is difficult to remove the ammonia nitrogen by adsorption. And other issues.

The air supply pipe 4b is connected to the lower part of the pumping pipe 4a and is also connected to the air pump 9. The air supply pipe 4b has a piping structure diverted above the filtration tank 2 in order to prevent the water pumped from the pumping pipe 4a from flowing into the air pump 9. By supplying air from the pore pump 9 through the air supply pipe 4b, a predetermined amount of water in the water tank 1 can be continuously pumped up from the pumping pipe 4a by the action of the air. It can be arbitrarily adjusted depending on the amount.
At the upper end of the air supply pipe / pumping pipe 4, a water spout 1 for flowing pumped water containing air into the benthic animal growth environment layer 3

A part of the pumped water flows down to the benthic-animal-growing environment layer 3, but the remaining water overflows onto the benthic-animal-growing environment layer 3. A drain pipe 11 for draining this overflowed water to the water tank 1 is provided on the upper side wall 2 a of the filtration tank 2. Since the water discharged from the drain pipe 11 to the water tank 1 contains air, that is, is peroxygen-containing water, the water in the water tank 1 can be stirred and aerated. In addition, the purified water discharge port 5 provided at the bottom of the filtration tank 2 has a benthic animal growth environment layer 3
It is a drain port for supplying the water purified / filtered in (1) into the aquarium 1. The drain port 5 has a structure capable of discharging purified water along the peripheral surface of the filtration tank 2 or along the tangential direction of the peripheral surface of the filtration tank 2. That is, the drainage port 5 faces the circumferential direction or the tangential direction. Thereby, the water in the water tank 1 can be smoothly stirred and aerated.

In the water purifying apparatus using the rotifer or the like of the present embodiment, the filtration tank 2 in which the rotifer 14 is made to inhabit the porous glass particle layer 7 is erected in the water tank 1 for growing seafood,
By supplying air to the benthic animal growth environment layer 3 and water in the aquarium 1, and circulating the water between the benthic animal growth environment layer 3 and the aquarium 1, The water in the aquarium 1 can be purified by using the residual food or excrement of the seafood as food of the rotifer to purify the water and circulating the purified water in the aquarium 1. That is, when the air pump 9 is operated and air is supplied from the air supply pipe 4b to the air supply pipe / pumping pipe 4, the water in the water tank 1 is pumped from the lower part of the pumping pipe 4a by the supply force of the air. It becomes air-containing water (peroxygen-containing water) and flows from the water outlet 10 formed in the upper part of the air supply pipe / pumping pipe 4, and at the same time, it overflows onto the benthic animal growth environment layer 3 and part of the water. Flows down through the benthic animal growth environment layer 3, and the remaining water is discharged into the water tank 1 from the drain pipe 11 formed on the upper side wall 2a of the filtration tank 2. Since the discharged water is air-containing water (peroxygen-containing water), the water in the water tank 1 is agitated and aerated. Further, the water flowing down to the benthic animal growth environment layer 3 is drained into the water tank 1 through the rock wool layer 8 and the porous glass particle layer 7 from the clean water discharge port 5 provided around the lower portion of the tank. It Here, as shown in FIG. 2, the purified water discharge port 5 has a structure for discharging along the tangential direction of the filtration tank 2 or along the periphery of the filtration tank 2, so that the water in the water tank 1 Flow can be generated and aeration can be performed, and the growth condition of the seafood growing in the aquarium can be made good. In addition, in the benthic animal growth environment layer 3, the rotifer that inhabits the porous glass particle layer 7 grows with the residual food and excrement of the seafood contained in the water flowing down as food. Since the residual food and excrement of seafood are removed from the water, the water flowing down from the benthic animal growth environment layer 3 is purified and filtered. Therefore, according to the water purification device of the present embodiment, the filtration layer 2
Thus, it is possible to circulate and purify the water in the water tank 1 while growing the rotifer.

EXAMPLE Next, in order to confirm the operation and effect of the above-described embodiment, a fish tank (volume 1.0t) and a filter tank (volume 0.4t) in which crocodile lived were prepared, The fish tank with 1000 cm of sea bream having a body length of 10 cm, the filter tank with 300 g of stag beetle inhabited (this example), and the one without stag beetle inhabited (comparative example), each had water in the water tank in the filter tank. Was circulated and the ammonia nitrogen concentration was examined at a predetermined time, and the results shown in FIG. 4 were obtained. In addition, 10% of the total weight of the sea bream was fed daily with the mixed diet, and the worms were not fed with the diet.

As can be seen from FIG. 4, in the case of this example, almost no increase in ammonia nitrogen was observed, whereas in the case of the comparative example, it could be confirmed that the increase in time series was observed. . From this, it was confirmed that the rotifer has a water purification effect. We also examined the habitat and growth of rotifers and snappers. As a result, in the present example, after 3 months, all were alive and good growth could be confirmed, whereas in the case of the comparative example, due to the increase of ammonia nitrogen from the middle, The fish tank has to be replaced. In addition, for this example, when the number of stag beetles was reduced along the way, an increase in ammonia nitrogen was observed, and the seafood that grows in the fish tank was the amount of stag beetle in the case of this tank volume. It was also found that it is preferably 43 times or less, and when it is 44 times or more, the amount of ammonia nitrogen becomes unstable. However, this depends on the type of fish and the volume of the aquarium.
