[0015] The working principle of the present invention is: according to the amount of medicine added, the threaded shaft 30 is rotated, and the threaded shaft 30 drives the trigger switch 2 32 and the pointing block 33 to rise and fall through the threaded sleeve 31, and the position of the pointing block 33 in the transparent scale area 2 is observed to control the moving position of the trigger switch 2 32, thereby controlling the single addition amount inside the quantitative box 26; Phosphate wastewater is added to the treatment box 1 through the wastewater pipe 2, and then the medicine box mechanism adds the medicine liquid to the quantitative box 26 through the adding pipe 34. The float 29 and the floating block 28 rise with the rise of the liquid level. When the floating block 28 rises and presses the trigger switch 2 32, it means that a certain amount of medicine liquid is added to the quantitative box 26. Then, the medicine box mechanism stops adding work, and at the same time, the valve of the inlet pipe 35 is opened, so that the certain amount of medicine liquid in the quantitative box 26 flows into the treatment box 1; Then, the motor 6 rotates forward and then reverses, so that the rotating shaft 7 and the rotating block 8 drive the positioning rod 9 and the reciprocating block 10 to rotate forward and then reverse, and the reciprocating block 10 drives the vertical stirring plate 12 and the horizontal stirring plate 13 to rotate through the vertical plate 11, and the waste water and the liquid medicine inside the treatment box 1 are stirred by the horizontal stirring plate 13. While the reciprocating block 10 rotates, the reciprocating block 10 and the threaded rod 5 are threadedly connected, so that the reciprocating block 10 drives the vertical stirring plate 12 and the horizontal stirring plate 13 to rise and then fall, and the waste water and the liquid medicine inside the treatment box 1 are stirred by the vertical stirring plate 12 rising and then falling, thereby improving the stirring and mixing efficiency; After the wastewater and the liquid medicine are mixed and stirred, they are left to stand for a period of time so that the phosphorus in the wastewater reacts with the medicine to generate insoluble precipitates. The precipitates sink to the bottom of the treatment box 1, and the circular floating plate 15 floats on the liquid surface inside the treatment box 1. Then, the precipitates are observed to be at the position of the transparent scale area 14, and the adjustment block 22 is pushed to move to the corresponding position on the scale line 20. The fastening bolt 24 is turned to press against the rubber strip 21 to fix the position of the trigger switch 23. The pump body 36 is controlled to work to pump the liquid in the treatment box 1 into the filter box 38, and the liquid is filtered and recycled through multiple filter plates 39. As the liquid level drops, the return float 15 drives the sliding rod 16, the pointing pressure block 17 and the telescopic tube to drop synchronously. When the return float 15 drops to the position of the sediment, the pointing pressure block 17 presses the trigger switch 23 to stop the pump body 36. Then, the valve outside the outlet pipe 3 is opened to discharge the sediment in the treatment box 1 for recycling. When the filter plate 39 needs to be cleaned or replaced, the buckle pull block 42 is pushed to move the compression spring 44. At the same time, the buckle pull block 42 drives the clamping block 45 to leave the clamping hole 47, and the multiple filter plates 39 are pulled out for cleaning or replacement through the pull plate 40.
