[0027] The specific steps are as follows: Step 1. Intermittent replacement of the filtration surface: Sewage is introduced into the transfer and detection tank 1 through the water inlet pipe 3. After being filtered by the filter plate 2 to remove solid impurities and detected by the detector 5, it is discharged through the water outlet pipe 4. During filtration, the drive motor 606 is started, causing the threaded sleeve 608 to drive the toothed plate 609 to reciprocate on the surface of the reciprocating screw 607. The reciprocating movement of the toothed plate 609 causes the gear 605 to reciprocally engage. The reciprocal engagement of the gear 605 synchronously drives the main shaft 601 and the arc-end push plate 604 to rotate reciprocally and equidistantly. When the arc-end push plate 604 rotates forward, it will push the single inclined panel 603, causing the water isolation cover 602 to rotate by a fixed angle. When the arc-end push plate 604 rotates in reverse, it will return to the flat surface of the next single inclined panel 603 through extrusion retraction and expansion reset. The intermittent rotation of the water isolation cover 602 synchronously drives the filter plate 2 to rotate intermittently, providing a new clean filtration surface for the water inlet pipe 3. The filter plate 2 is subjected to the anti-reverse cooperation of the ratchet 610 and the pawl 612, causing the filter plate 2 to only rotate in one direction; Step 2. Intermittent cleaning of the filtration surface: The intermittent rotation of the water isolation cover 602 synchronously drives the cleaning shaft 702 and the arc-shaped scraping blade 703 to rotate through the transmission cooperation of the first auxiliary pulley 704, the first main pulley 705, and the first belt 706. The rotating arc-shaped scraping blade 703 continuously transfers the solid impurities on the top of the filter plate 2 into the interior of the arc-shaped cover 701, and finally causes the impurities to accumulate and drain water on the top of the partition filter plate 802; Step 3. Intermittent compression and discharging of solid waste residues: During the reciprocating rotation of the main shaft 601, the main shaft 601 synchronously drives the cam 804 to reciprocally push the pressing plate 803, causing the pressing plate 803 to reciprocally push the impurities on the top of the partition filter plate 802 until the impurities accumulate at the baffle 805 and are squeezed to dehydrate. Along with the squeezing and dehydration of the impurities, the impurities will finally push open the baffle 805, causing the impurities to be discharged to the outside. When the baffle 805 moves under force, it will, through the path cooperation of the sliding opening 806 and the inclined rod 807, as well as the chute plate 814 and the chute block 815, cause the baffle 805 to disengage from the extrusion contact with the impurities, enabling the impurities to be discharged smoothly. After the impurities are discharged, the baffle 805 automatically resets through the pulling-back of the fourth spring 813 and its own gravity; Step Four: Intermittent dredging of filter screen holes: When the main shaft 601 rotates reciprocally, the main shaft 601 synchronously drives and cooperates with the second auxiliary pulley 905, the second main pulley 906 and the second belt 907, prompting the threaded rod 902 to rotate forward and backward synchronously. When the threaded rod 902 rotates forward, the internal thread cylinder 903 drives the piston plate 904 to press down inside the air cylinder 901, prompting the air inside the air cylinder 901 to be emptied. After the filter plate 2 rotates intermittently forward to the designated position along with the main shaft 601, the main shaft 601 will reverse synchronously with the threaded rod 902, prompting the internal thread cylinder 903 to drive the piston plate 904 to draw air upward inside the air cylinder 901. When the piston plate 904 draws air, the negative pressure ventilation plate 911 will move upward under negative pressure. The movement of the negative pressure ventilation plate 911 drives the T-shaped frame 912 to lift, prompting the T-shaped frame 912 to press against the abutting block 915 by lifting the tilting plate 913, so that the cover 914 fits against the top of the filter plate 2. Along with the continuous air drawing of the piston plate 904, the impurities in the filter holes of the filter plate 2 are gradually drawn out to the top of the filter plate 2.
