It should be noted that, in the normal wastewater treatment mode, the side of the spiral blade 21 rotates a circle to push the lower extension rod 43, and periodically pushes the lower extension rod 43 in the continuous operation process, and when the push extension rod 43 moves, the extension rod 43 drives the sealing plate two 61 to contract inward and move, at this time, the sealing plate one 53 is located in the conduit 41, that is, the conduit 41 is sealed, and the treatment liquid between the sealing plate two 61 and the sealing plate one 53 pushes the sealing gasket 64 to deflect, at this time, the base plate 63 is opened, and the treatment liquid originally located on one side of the sealing plate two 61 away from the liquid suction pipe 2 is pressed into the other side of the sealing plate two 61 from the flow guide hole 62 due to the water pressure;

when the spiral blade 21 continues to rotate, the spiral blade 21 is separated from the extension rod 43, the second sealing plate 61 is pushed to reset under the action of the elastic force of the second spring 65, it is to be supplemented that the sealing gasket 64 is always pulled by the third spring 66, so that the sealing gasket 64 can be instantly pulled to be attached to the second sealing plate 61 under the condition that the second sealing plate 61 stops moving inwards, but note that the elastic force of the third spring 66 is always smaller than that of the second spring 65 in the whole moving process of the second sealing plate 61, so as to avoid influencing the maintenance of the position of the second sealing plate 61 in the straight-through pipe 42 under the normal state;

when the extension rod 43 is separated from the spiral blade 21, the spring third 66 pulls the sealing gasket 64 to cling to the sealing plate second 61 to seal the straight through pipe 42, at the same time, when the spring second 65 pushes the sealing plate second 61 to reset and move, negative pressure is generated between the sealing plate second 61 and the sealing plate first 53, the sealing plate first 53 is sucked by the negative pressure, and the spring first 54 continues to stretch until the sealing plate first 53 is separated from the guide pipe 41 and enters the straight through pipe 42, the treatment liquid in the temporary storage box 3 is sucked into the straight through pipe 42 by the negative pressure, and the process is repeated when the extension rod 43 is pushed by the subsequent spiral blade 21, so that the treatment liquid is periodically added to the spiral wastewater in the liquid pumping pipe 2, the efficient mixing of the treatment liquid is ensured, and the treatment efficiency is effectively improved.

Further, a transparent observation window 7 is provided on the side wall of the temporary storage tank 3 so as to observe the remaining amount of the treatment liquid in the temporary storage tank 3, thereby facilitating the real-time addition.

Referring to fig. 9, further, feed liquor pipe 23 tip is provided with a shower nozzle 8, the orifice slope of this shower nozzle 8, and this shower nozzle 8 utilizes sealed bearing to rotate with feed liquor pipe 23 and is connected, and then at 8 in-process that last blowout waste liquid of shower nozzle, its blowout rivers are the slope, and then utilize interact, spray when order to order about shower nozzle 8 to last the rotation in the opposite direction with rivers slope direction, further improvement waste liquid adds the homogeneity of in-process in the waste water treatment box, guarantee that high-efficiency processing uses
