When the filter drum is used, sewage entering the water inlet chamber 1.10 enters the filter drum 1.5 from the first through hole 1.8 in an overflow mode, and under the action of gravity and force in the centrifugal direction generated when the filter drum 1.5 rotates, water can fall below the filter drum 1.5 through the filter drum 1.5 and is discharged from the second through hole 1.22; the particulate impurities in the sewage are left inside the filter drum 1.5 under the filtering action of the filter drum 1.5. And through the setting of drive assembly 1.4 for the use of whole filter cylinder 1.5 is even, improves filter cylinder 1.5's utilization ratio.

Preferably, the lower edge of the first through hole is in the shape of a circular arc concentric with the filter drum, and a sealing strip attached to the inner wall of the filter drum is fixed on the first through hole. Wherein, this sealing strip 1.23 one end is fixed on first through-hole 1.8 border, and the other end is in the outside of ring 1.54 and the laminating of filter drum 1.5 inner wall for sewage can not leak the filter drum 1.5 outside from between filter drum 1.5 and the filter chamber 1.1 inner wall. In other words, by means of the sealing strip 1.23, it is ensured that all the sewage enters the inside of the filter drum 1.5, i.e. all the sewage needs to be filtered by the filter drum 1.5 before reaching the second through hole 1.22.

Further, a water receiving tank 1.24 is arranged inside the filtering roller 1.5, the water receiving tank 1.24 is fixed on the inner wall of the filtering chamber 1.1, the opening of the water receiving tank 1.24 faces upwards, a slag discharging port (not marked in the figure) is arranged at the bottom of the water receiving tank 1.24, a slag discharging pipeline 1.9 is connected to the slag discharging port, and one end of the slag discharging pipeline 1.9 extends to the outer side of the filtering chamber 1.1; a washing water pipe 1.2 is fixed at the upper end or above the filtering chamber 1.1, the washing water pipe 1.2 is arranged right above the filtering roller 1.5, the central axis of the washing water pipe 1.2 is parallel to the central axis of the filtering roller 1.5, a spray head 1.3 is fixed on the washing water pipe 1.2, and the spray head 1.3 is arranged towards the water receiving tank.

In the aforesaid, because filter cylinder 1.5 rotates at drive assembly 1.4's drive, consequently, paste the granule impurity at filter cylinder 1.5 internal face and rotate along with filter cylinder 1.5, when granule impurity turned to higher position, overcome the power of the centrifugal direction that filter cylinder 1.5 produced when rotating under the weight effect of self, and then granule impurity drops in the water receiving tank, then from row cinder notch discharge filter chamber 1.1, realize the filtration treatment of sewage, granule impurity can discharge automatically, make the clearance more convenient, and prolonged the manual cleaning time to filter cylinder 1.5.

In practical application, one end of the flushing water pipe 1.2 is sealed, the other end is connected with a clean water source through a pipeline, and a booster pump (not shown in the figure) is connected in series on the pipeline.

In a preferred embodiment, the partition board 3.2 comprises two first boards 3.21 and two second boards 3.22 which are vertically arranged, a third through hole 3.23 for water to pass through is arranged at the lower end of the first board at the front end of the water flowing direction, the upper end of the second board arranged at the rear end of the water flowing direction is lower than the upper end of the first board, and the lower end of the second board is attached to the bottom of the biochemical pool 3, so that the water can form a S-shaped flowing direction.

Better, 3 lower extremes in biochemical pond and the grid plate 3.3 of having laid in the top of third through-hole for when the water got into by each space of baffle 3.2 divided from the top, through passing through the third through-hole after the space of biochemical bacterium's material back entering grid plate below, make water more conveniently pass through the position of baffle 3.2. In other words, because the biochemical bacteria are flocculent or water-permeable solids, the circulation of water can be influenced, and the space below the grid plate is larger than the third through holes through the arrangement of the grid plate, so that water can be more quickly concentrated in the space below the grid plate and then passes through the third through holes, and the circulation of water can be ensured.

Specifically, an oxygen increasing component 4.1 is further fixed on the side wall of the oxygen increasing pool 4, and an air outlet end of the oxygen increasing component 4.1 is arranged in the oxygen increasing box body. The oxygen increasing component can be an oxygen increasing pump or an oxygen cylinder, the oxygen increasing component 4.1 can compress air and pump the air into the water body in the oxygen increasing pool 4, so that the contact area between the air and the water body is increased, the oxygen content of water is improved, and when the air is sprayed out of the water, the water is pushed to move, and partial oxygen can be effectively dissolved in the water. Preferably, the part of the air outlet end of the oxygen increasing component 4.1 in water is provided with an aeration pipe, so that the oxygen increasing effect is improved.

In a preferred embodiment, the inside of the oxygenation box body is further provided with a detector 4.2 and a temperature adjusting component at one end far away from the biochemical pool 3. The probe of the detector 4.2 and a temperature regulating assembly (not shown, placed below the detector) are placed in the water, the temperature regulating assembly preferably being a heating pipe for temperature regulation of the water to avoid that the water grows slower due to the lower temperature of the water. The detectors 4.2 include PH, temperature and oxygen content detection.

In practical application, the temperature adjusting component, the oxygenation component 4.1 and the detector 4.2 are connected to the same controller, and the data provided by the detector 4.2 is used for controlling the operation of the temperature adjusting component and the oxygenation component 4.1, so that water is kept at a better quality, and the healthy growth of aquatic products is ensured.

In the above, when there is a height difference between the microfiltration machine 1, the protein separator 2, the biochemical tank 3 and the aeration tank 4, the water pump may be provided to lift water by the water pump, so that the water may circulate among the microfiltration machine 1, the protein separator 2, the biochemical tank 3 and the aeration tank 4.

According to the invention, the aeration pipe 5.3 is arranged in the water inlet pipeline 5.1 for communicating the fish pond and the sewage treatment device, the two ends of the aeration pipe 5.3 are connected with the air compressor 5.4, and a liquid circulation channel is formed between the outer wall of the aeration pipe 5.3 and the inner wall of the water inlet pipeline 5.1. When using, in air pump to aeration pipe 5.3 through air compressor 5.4, and in the liquid circulation passageway between aeration pipe 5.3 outer wall and inlet channel 5.1 inner wall through aeration pipe 5.3 blowout, and then bump the sewage of circulation in the liquid circulation passageway, consequently make sewage be in turbulent state when circulating in the liquid circulation passageway, and then produce the impact to aeration pipe 5.3 outer wall and inlet channel 5.1 inner wall constantly, avoid the impurity in the sewage to glue on aeration pipe 5.3 outer wall and inlet channel 5.1 inner wall, and then avoided inlet channel 5.1 to cause the jam.

In addition, in the water treatment system mainly comprising the filter chamber 1.1, the disinfection chamber 1.13, the protein separator 2, the biochemical pool 3 and the oxygenation pool 4, the disinfection chamber 1.13 is arranged behind the filter chamber 1.1, namely, the water body is immediately disinfected after being filtered, and microorganisms in the water body are killed, so that the microorganisms are prevented from continuously propagating in subsequent treatment. Therefore, when the water treatment system of this application is disinfecting, compare in current water clean system, the microorganism that need kill is less for can reduce the power of UV disinfection subassembly, reduce the energy consumption.
