Due to the rotation of the aforementioned stirring assembly, the mixed gas of ozone and air can fully contact with the sewage, so that the sewage in various places in the lower treatment box 1 can contact with ozone, thereby improving the water treatment capacity.

[0039] A drain pipe 12 is fixedly connected to the side wall of the lower processing box 1, and the drain pipe 12 is connected to the sterilization chamber of the lower processing box 1. A valve 13 for controlling the connection of the drain pipe 12 is installed on the drain pipe 12.

[0040] See Figure 3The filter frame is provided with a filter component, and the filter component includes:

[0041] A plurality of hanging ears 14 can be hung on the upper edge of the upper filter frame 2. In this embodiment, there are four hanging ears 14. Assuming that the middle line of the upper surface wall of the upper filter frame 2 parallel to the Y direction is line G, the four hanging ears 14 are divided into two groups, and the two groups of hanging ears 14 are symmetrically arranged along line G.

[0042] Lifting rods 15, in this embodiment, there are two lifting rods 15. The axes of the two lifting rods 15 are parallel to the line G, and the two lifting rods 15 are respectively fixedly connected to the two hanging ears 14 of the same group.

[0043] The filter screen plate 16 is fixedly connected to the plurality of hanging ears 14. The filter screen plate 16 is horizontally placed in the filter cavity, and the cross-sectional area of ​​the filter screen plate 16 is equal to the cross-sectional area of ​​the filter screen plate 16.

[0044] The hanging ear 14 is provided with a scraper assembly, which is located above the filter plate and includes:

[0045] The screw rod 17 is rotatably connected to one set of the hanging ears 14;

[0046] The scraper motor 18 has its non-rotating shaft end fixed on one of the hanging ears 14 . The rotating shaft of the scraper motor 18 is fixedly connected to the screw rod 17 . The rotating shaft of the scraper motor 18 coincides with the rotating shaft axis of the screw rod 17 . The scraper motor 18 is used to rotate the screw rod 17 .

[0047] A first connecting frame 19 is threadedly connected to the screw rod 17;

[0048] The cross frame 20 is detachably connected to the first connecting frame 19 by bolts and is arranged horizontally; the cross frame 20 is located above the filter plate 16;

[0049] The bristles 21 are elastic and densely distributed on the lower surface wall of the truss. The bristles 21 abut against the upper surface wall of the filter plate 16. Figure 3 The middle bristles 21 are only shown schematically.

[0050] A second connecting frame 22, fixed on the cross frame 20;

[0051] The guide rod 23 is fixed on another set of hanging ears 14. The second connecting frame 22 is movably mounted on the guide rod 23. The second connecting frame 22 can only move along the axis of the guide rod 23. The axis of the guide rod 23 is parallel to the Y direction.

[0052] After the scraper motor 18 rotates, the scraper motor 18 drives the screw rod 17 to rotate. The first connecting frame 19, the cross frame 20, the bristles 21 and the second connecting frame 22 can only move along the axis of the guide rod 23 as a whole, and the screw rod 17 is threadedly connected to the whole, so the first connecting frame 19, the cross frame 20, the bristles 21 and the second connecting frame 22 move along the axis of the guide rod 23 as a whole under the action of the screw rod 17. The bristles 21 contact the upper surface wall of the filter plate 16, and scrape the solid residue filtered by the upper surface wall of the filter plate 16 to one or both ends of the Y direction, so that the solid residue does not block the mesh in the middle of the filter plate 16, and the mesh in the middle of the filter plate 16 has filtering capacity. The user then regularly removes the solid residue accumulated at both ends of the Y direction. By pulling the lifting rod 15 upward, the hanging ear 14 is no longer placed on the edge of the upper filter frame 2, and the entire filter assembly can be lifted out from the upper end of the filter chamber, which is convenient for cleaning the filter assembly.

[0053] A water inlet pipe 24 is fixed on the side wall of the filter frame. The water inlet pipe 24 is communicated with the filter cavity, and the water inlet pipe 24 is located above the filter plate 16 .

[0054] Usage process:

[0055] The water inlet pipe 24 is connected to a water pump to pump the river sewage to the top of the filter plate 16. After the filter plate 16 filters the solid residue in the sewage, the sewage flows into the sterilization chamber from the through hole.

[0056] The water pump stops after running for T1, which means that the sewage in the sterilization chamber has submerged the stirring component.

[0057] The person turns on the power mechanism, and the stirring motor 7 of the power mechanism stirs the stirring assembly in the sewage. At the same time, the person also turns on the ozone generator 9 and the air compressor 10. The mixed gas of ozone and air is pressed into the aeration pipe 11 by the air compressor 10 and sprayed into the sewage from the hole of the aeration pipe 11. Since the sewage is stirred by the stirring assembly, the sewage can be mixed with the mixed gas of ozone and air as much as possible, and the ozone sterilizes the bacteria in the sewage. Since the mixing ability of ozone is enhanced, the water treatment capacity is improved.

[0058] The power mechanism, ozone generator 9 and air compressor 10 stop running for T2, and the sewage treatment in the sterilization chamber is considered to be completed, and the power mechanism, ozone generator 9 and air compressor 10 are turned off. The person opens the valve 13, and the sewage in the sterilization chamber is discharged from the drain pipe 12 into the river or for testing.

[0059] Close valve 13 again, start the water pump again, and then proceed to the next round of sewage treatment.

[0060] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
