Two third electric cylinders 502 are fixed to the left end face of the processing box 1, and the protruding ends of the two third electric cylinders 502 are fixed with sealing frames 503. The sealing frames 503 are located inside the processing box 1, and the top surface of the sealing frame 503 contacts the bottom surface of the auxiliary block 501. The sealing frames 503 and the auxiliary blocks 501 are arranged in an staggered manner. When the two third electric cylinders 502 are extended, the processing box 1 is in a separated state under the action of the sealing frame 503 and the auxiliary block 501. The processing box 1 is divided into two areas by the sealing frame 503 and the auxiliary block 501, which is convenient for the subsequent rapid collection of sediment.

At this time, the processing box 1 can be divided into two by the sealing frame 503 and the auxiliary block 501. The two areas are separated by the sealing frame 503 and the auxiliary block 501. At this time, multiple first discharge pipes 103 and second discharge pipes 604 are opened at the same time. At this time, the waste liquid is discharged through the first discharge pipes 103 and the second discharge pipes 604. After the second discharge pipe 604 completes the discharge of the liquid in the storage box 602, the two fourth electric cylinders 601 are driven to extend. Under the push of the two fourth electric cylinders 601, the storage box 602 is taken out. At this time, the sediment in the storage box 602 can be collected. Compared with the existing device, the sediment can be collected without waiting for all the liquid in the processing box 1 to be discharged, which saves time.

[0036] Embodiment 2: Based on embodiment 1, it further includes: the top of each auxiliary block 501 is an inclined structure, which can prevent sediment from remaining on the auxiliary block 501 during use.

[0037] The specific usage and function of this embodiment are as follows: During use, wastewater is added to the treatment box 1 through the liquid inlet pipe 102, and then filtered through the filter hole 203 on the filter box 202. The filtered wastewater enters the lower position of the filter box 202, and the additive is added through the addition pipe 104. Then the motor 403 is controlled to rotate. Under the mixing action of the impeller 402, the wastewater and the additive can be fully contacted. Finally, under the action of the additive, the titanium ions react with certain chemical substances in the additive to form a precipitate; at the same time, under the continuous tossing of the impeller 402, the mounting frame 304 and the cleaning rod 305 reciprocate up and down, and the reciprocating up and down movement of the cleaning rod 305 realizes the continuous clearing of the filter hole 203; when taking out the precipitate, the two third electric cylinders 502 are first driven to extend. At this time, through the sealing frame 50 3 and the auxiliary block 501 can separate the processing box 1 into two areas, and the two areas are separated by the sealing frame 503 and the auxiliary block 501. At this time, multiple first discharge pipes 103 and second discharge pipes 604 are opened at the same time. At this time, the waste liquid is discharged through the first discharge pipes 103 and the second discharge pipes 604. After the second discharge pipe 604 has completed the discharge of the liquid in the storage box 602, the two fourth electric cylinders 601 are driven to extend. Under the push of the two fourth electric cylinders 601, the storage box 602 is taken out, and the sediment in the storage box 602 can be collected at this time; when removing the residue inside the filter box 202, the two first electric cylinders 201 are driven. Under the drive of the two first electric cylinders 201, the filter box 202 is moved out of the processing box 1, which facilitates the cleaning of the residue inside the filter box 202.
