In this embodiment, the horizontal height of the mixing tank 6 is lower than the horizontal height of the treatment tank 1. The purified liquid stored in the liquid storage tank 7 can be an oxidant (such as chlorine and ozone, used to oxidize and decompose organic pollutants and kill pathogenic microorganisms) or a dephosphorizer (such as ferric chloride and aluminum sulfate, used to remove phosphorus in water and prevent eutrophication of water bodies). The first filter screen 2 and the second filter screen 3 divide the treatment tank 1 into three accommodating chambers. The filter hole diameter of the first filter screen 2 is larger than the filter hole diameter of the second filter screen 3. After the sewage is passed into the treatment tank 1, the first filter screen 2 performs a preliminary filtration on the sewage, mainly filtering out larger garbage. The sewage filtered by the first filter screen 2 enters the accommodating chamber between the first filter screen 2 and the second filter screen 3. At this time, the second filter screen 3 filters the sewage. The filtered sewage finally flows into the mixing tank 6, and the mixing tank 6 mixes the sewage with the purified liquid to fully purify the sewage. When the second filter plate 3 filters the sewage, due to the small pore size of the filter holes of the second filter plate 3, these impurities are easy to block the filter holes of the second filter plate 3. At this time, the power component is started, and the power component drives the mounting block 4 to rise and fall. The cleaning piece on one side of the mounting block 4 is always kept in contact with the side wall of the second filter plate 3 under the drive of the spring 5. As the mounting block 4 rises and falls, the cleaning piece removes the impurities blocked on one side of the second filter plate 3, thereby ensuring the filtration efficiency of the second filter plate 3. In the process of cleaning the second filter plate 3, there is no need to remove the second filter plate 3. The second filter plate 3 is cleaned when it is in working state, thereby ensuring the sewage treatment capacity of the device.

When cleaning the second filter screen plate 3, start the first motor 9, the first motor 9 drives the screw rod 8 to rotate, and when the screw rod 8 rotates, the slider is driven to rise or fall in the slide groove, so that the mounting block 4 is also raised or lowered, so that the cleaning part on one side of the mounting block 4 cleans one side of the second filter screen plate 3. Preferably, a guide rod is vertically and rotatably arranged in another slide groove, and the guide rod is slidably connected to the corresponding slider, so that the lifting and lowering of the mounting block 4 is more stable. As another embodiment, the power assembly can also be a cylinder driving the mounting block 4 to rise and fall, or the motor drives the mounting block 4 to rise and fall in the way of convolution of the pull rope, which are conventional means and will not be elaborated here.

[0022] like Figure 4 As shown, further, the cleaning member includes: a connecting block 10, the connecting block 10 is slidably arranged in the mounting groove, one side of the connecting block 10 is fixedly connected to the spring 5, and a scraper 11 is arranged on the side of the connecting block 10 away from the spring 5. During the process of the mounting block 4 being lifted and lowered, the spring 5 pushes the scraper 11 to always abut against one side of the second filter screen plate 3, so that the scraper 11 can scrape off the impurities accumulated on one side of the second filter screen plate 3 during the process of the mounting block 4 being lifted and lowered, thereby cleaning the second filter screen plate 3 and preventing it from clogging the second filter screen plate 3.

[0023] like Figure 5 As shown, further, the cleaning member includes: a connecting block 10, the connecting block 10 is slidably arranged in the mounting groove, one side of the connecting block 10 is fixedly connected to the spring 5, a sponge 12 is arranged on the side of the connecting block 10 away from the spring 5, and a plurality of protrusions 13 are arranged on the side of the sponge 12 facing the second filter screen plate 3.
