Because the filtering cotton bag 10 on the water permeable framework 11 absorbs water, the weight of the filtering cotton bag is too large, and the weight of the inner barrel 9 of the filtering box is relatively small, so that the inner barrel 9 of the filtering box is driven by the buoyancy ring 13 to move vertically more easily.

As shown in fig. 4, when the filter unit is horizontally placed, the inner filter tank barrel 9, the sealing disk 18 and the floating ring 13 are not needed, because the outlet of the outer filter tank barrel 8 is relatively high, which does not affect the outflow of purified water and sewage generated after cleaning the filter unit. The nozzle 25 is preferably arranged at the lower side of the filtering unit, so that the sewage dropping from the filtering cotton bag 10 washed by the nozzle 25 can be collected at the bottom of the outer barrel 8 of the filtering tank under the action of gravity and discharged out of the physical filtering tank 2 by the sewage pump 14.

In the above embodiment, the physical filter box 2 and the biochemical filter box 3 may be an integral body, or may be formed by separately overlapping and connecting them. The physical filtering box 2 and the biochemical filtering box 3 can be independently applied to the purification and filtration of the fish tank pool and play a corresponding role.

The cleaning pump 22 can be installed in the biochemical filtering area 36 of the biochemical filtering tank 3, so that the filtering unit can be cleaned by using raw water, firstly, domestic water is saved, the biological properties of the second raw water, such as temperature, mineralization degree, pH value and the like, are consistent with the working environment of the filtering cotton bag 10, the cleaning of the raw water cannot cause the stress death of nitrobacteria attached in the filtering cotton bag 10, and the positive effect on water quality guarantee is achieved.

2. The biochemical filtering area is added with nitrobacteria, and the bacteria are implanted, bred and split in a bacteria room. Nitrobacteria belong to aerobic bacteria, and the bacteria room is soaked in the water in the grid pond, so that the dissolved oxygen amount of the water in the bacteria room is small, and the water in the bacteria room cannot flow through the bacteria room in time, so that the oxygen exchange of the water in the bacteria room is limited, and the growth and the work of the nitrobacteria are not facilitated.

In summary, the following structure is specifically adopted in the embodiment to solve the problem of efficient biochemical filtration:
