The working principle is as follows: when the device is used, an external power supply is connected, as shown in fig. 1 or 2, the bidirectional motor 11 is started to drive the screw rod 9 to rotate, so that the upper draining plate 12 rises along with the longitudinal slide block 10, so that the side wall of the upper draining plate 12 is separated from the port of the feed pipe 22, the pipe orifice of the feed pipe 22 is opened, wastewater flows into the solid-liquid separation chamber 1 from the feed pipe 22 and is positioned between the upper draining plate 12 and the lower draining plate 15, when the wastewater flows to a certain amount, the bidirectional motor 11 is started to drive the screw rod 9 to rotate reversely, so that the upper draining plate 12 descends along with the longitudinal slide block 10, when the upper draining plate 12 descends, the solid-liquid mixture between the upper draining plate 12 and the lower draining plate 15 is pushed downwards, so that the solid-liquid mixture and the lower draining plate 15 descend together, when the lower draining plate 15 descends to be separated from a draining hole 27 on the inner wall of the solid-liquid separation chamber 1, liquid in the solid-liquid mixture enters the liquid storage chamber 23 from the draining hole 27, the solid in the solid-liquid mixture is continuously positioned on the lower draining plate 15, the upper draining plate 12 continuously pushes the lower draining plate 15 and the solid to descend, when the lower draining plate 15 descends to the lowest position (that is, when the compression amount of the supporting spring 14 reaches the maximum), the upper draining plate 12 continuously descends and further presses the solid on the lower draining plate 15, so that the liquid in the solid is more completely separated, it should be noted that when the lower draining plate 15 descends to the lowest position, the first draining holes 27 distributed at the lowest part

sliding blocks 16 loosens along with the descending process of the lower draining plate 15, thereby ensuring that the lower draining plate 15 descends, the transverse sealing slide blocks 16 positioned in the two ends of the transverse sealing slide blocks are attached to the inner wall of the solid-liquid separation chamber 1, so that liquid is prevented from flowing into a slag storage cavity from the space between the transverse sealing slide blocks 16 and the inner wall of the solid-liquid separation chamber 1 in the solid-liquid separation process to influence the solid-liquid separation effect, the rolling shaft 18 enables the rolling gear 20 to idle under the action of the one-way bearing in the descending process of the rack plate 17, the rolling shaft 18 can not roll the loose connecting rope 29, the attaching state of the transverse sealing slide blocks 16 and the inner wall of the solid-liquid separation chamber 1 is indirectly ensured, when the rack plate 17 descends to the lowest position along with the lower draining plate 15, the electromagnet 31 is electrified, the permanent magnet blocks 32 on the bottom end of the rack plate 17 are adsorbed on the electromagnet 31, the rack plate 17 and the lower draining plate 15 are fixed, and then the two-way motor 11 is started to drive the screw rod 9 to rotate reversely, the longitudinal slide block 10 of the upper draining plate 12 is lifted, when the upper draining plate 12 is lifted to just block the feeding pipe 22, the electromagnet 31 is powered off, the lower draining plate 15 and the rack plate 17 are lifted to the initial position under the action of the supporting spring 14, and in the lifting process of the rack plate 17, a section of rack distributed on the surface of the rack plate is meshed with the rolling gear 20 and drives the rolling shaft 18 to rotate under the action of a one-way bearing, the rolling shaft 18 rolls the connecting rope 29 in the rotating process, in the rolling process of the connecting rope 29, the transverse sealing slide block 16 overcomes the acting force of the return spring 26 under the action of the connecting rope 29 and moves to one end of the return spring 26 along the transverse sliding chute 24, so that a gap is formed between the inner wall of the solid-liquid separation chamber 1 and the lower draining plate 15, and separated solids on the transverse sealing slide block fall from the gap and enter a slag storage cavity through the slag outlet 28 to be collected, after the rack plate 17 continuously rises to the rack on the surface of the rack plate and is separated from the rolling gear 20, the transverse sealing slide block 16 moves towards the inner wall of the solid-liquid separation chamber 1 under the action of the return spring 26 and returns to the initial position, meanwhile, the connecting rope 29 is driven by the transverse sealing slide block 16 to pay off from the rolling shaft 18, the liquid flowing into the liquid storage chamber 23 is conveyed into the adjusting chamber 2 through the liquid conveying pump on the liquid conveying pipe, the liquid entering the adjusting chamber 2 is processed and then sequentially enters the anaerobic chamber 3, the aerobic chamber 4 and the MBR processing chamber 5 to be processed one by one, and the processed liquid is finally recovered into the water storage chamber 6.
