[0042] The present invention realizes separation between upper impurities and lower clear liquid through layered components, thereby reducing the difficulty of clear water recovery.

[0046] In a further optimized solution, a strip groove is provided between adjacent first through holes 15, the strip groove is perpendicular to the axis of the layered plate 13, a sealing strip 26 is fixedly connected in the strip groove, and the sealing strip 26 is staggered with the third through hole 17. The setting of the sealing strip 26 can make the adjacent first through holes 15 relatively independent, and when the backing plate 11 and the layered plate 13 are facing each other, the first through hole 15 and the second through hole 16 are facing each other, and at this time, the sealing strip 26 is between the second through hole 16 and the third through hole 17.

[0047] Further optimizing the scheme, a pressure relief hole 27 is provided on the side wall of the purification tank 3, and a one-way pressure relief valve is installed in the pressure relief hole 27. The setting of the pressure relief hole 27 can be used to relieve pressure after the filter membrane 25 is blocked, ensuring that the device can drain water smoothly. At the same time, in this embodiment, the branch pipe 33 at the end of the water pipe 32 is set below the pad 11, so that water can be inlet from below, so that the water level in the sewage purification zone 5 gradually rises, so that the filter membrane 25 can be reversely flushed by adjusting the position of the filter membrane 25 to ensure the filtering effect.

[0048] Further optimizing the scheme, the micro-nano bubble generating mechanism includes a micro-nano bubble generator 28, the output end of the micro-nano bubble generator 28 is fixedly connected to a delivery pipe 29, and the delivery pipe 29 is fixedly connected to four groups of distribution pipes 30, and the four groups of distribution pipes 30 respectively pass through the side wall of the purification tank 3 and extend into the sewage purification zone 5. The micro-nano bubble generator 28 adopts the existing technology and is not specifically limited in this embodiment.

Three groups of filter plates 31 can be arranged, and the filter plates 31 are arranged between the water inlet and the drain of the filter tank 1, so that the sewage entering the filter tank 1 is filtered through the three layers of filter plates 31 in sequence, thereby ensuring the filtering effect. The filter plates 31 are fixed to the filter tank 1 by parts such as a frame and fixing bolts, so as to ensure the convenience of disassembly of the filter plates 31.

[0050] A further optimized solution is that the water delivery component includes a water delivery pipe 32, one end of the water delivery pipe 32 is fixedly connected to the drain outlet of the filter tank 1, the other end of the water delivery pipe 32 is inserted into the mounting tube 2, and the outer wall of one end of the water delivery pipe 32 located in the mounting tube 2 is fixedly connected with four groups of branch pipes 33 at equal intervals in the circumferential direction, the four groups of branch pipes 33 are respectively arranged corresponding to the four groups of water inlets on the mounting tube 2, an electromagnetic control valve is installed on the branch pipe 33, and a water delivery pump 34 is installed on the water delivery pipe 32.

[0051] According to a further optimization scheme, an annular groove is provided on the side wall of the mounting groove 12, and an annular clamp is fixedly connected to the side wall of the layered plate 13.

[0052] The cooperation between the annular block and the annular groove can realize a stable connection between the layered plate 13 and the partition 4, and at the same time, the layered plate 13 and the partition 4 are prevented from being separated in the vertical direction while ensuring stable rotation between the two. At the same time, a sealing strip 26 is arranged between the layered plate 13 and the partition 4, so that the relative sealing between the two can be ensured.

[0053] During operation, the sewage first enters the filter tank 1, and is filtered through the filter plate 31 in the filter tank 1, and then is input into the purification tank 3 through the water pipe 32 and the water pump 34. The micro-nano bubble generator 28 generates micro-nano bubbles, which enter the diversion pipe 30 through the delivery pipe 29, and then enter the sewage purification zone 5 respectively. The micro-nano bubbles have the characteristics of slow rising speed, long residence time, high dissolution efficiency, self-oxygenation, negative charge, and rich in strong oxidizing hydroxyl free radicals (·OH), etc., and also have super high redox potential. The super strong redox effect generated by the micro-nano bubbles can degrade water pollutants that are difficult to decompose under normal conditions in the water, thereby purifying the water quality. The micro-nano bubbles carry impurities through the first through hole 15 and the layered plate 13 on the partition plate 4. The second through hole 16 on the backing plate 11 rises above the water surface, and then the linear motor 14 controls the pad 11 to rise, compressing the compression spring 22, so that the first sleeve 20 and the second sleeve 21 are retracted. When the stratification plate 13 reaches the stratification position of the impurities and the lower clear liquid, the electric slip ring 19 rotates to drive the drive ring and the stratification plate 13 to rotate. Then the third through hole 17 on the stratification plate 13 corresponds to the first through hole 15 on the pad 11, and the first through hole 15 and the second through hole 16 are misaligned. Then the lower clear liquid is extracted through the clean water pump 10 and the clean water pipe 9, and the upper impurities are filtered above the stratification plate 13 under the action of the filter membrane 25. Finally, the impurities on the stratification plate 13 can be directly cleaned, and multiple groups of sewage purification intervals 5 work alternately, thereby improving the sewage treatment efficiency of the device.

The barrier hood at the rear end is arranged in the injection hood. A plurality of water-permeable holes are arrayed on the barrier hood, and the apertures of the water-permeable holes on the barrier hood decrease successively along the water conveying direction of the shunt pipe 30. In this way, the bubbles generated by the micro-nano bubble generator 28 will collide in the shunt pipe 30 and finally form dense and uniform bubbles through the blocking collision of the barrier hood to mix in the sewage to improve the sewage treatment effect.
