One end of the stirring shaft extends into the interior of the device body and is connected to a stirring paddle. The stirring paddle comprises four U-shaped stirring blades symmetrically arranged along the stirring shaft, and the top projection shape of the stirring paddle is a cross. A filter plate is fixed at a position below the stirring shaft in the device body.

[0006] As a further improvement of the utility model, a plurality of auxiliary paddles are fixed on the U-shaped stirring blade along its height direction, and the auxiliary paddles include four auxiliary stirring blades evenly fixed on the U-shaped stirring blade, and the auxiliary stirring blade is provided with a plurality of circular through holes. The setting of the auxiliary paddles can speed up the mixing of the liquid medicine and the wastewater, and the sedimentation efficiency is high, and the water treatment effect is good.

[0007] As a further improvement of the present invention, the auxiliary stirring blade is an arc-shaped blade.

[0008] As a further improvement of the utility model, a disc-shaped tube connected to the drug-adding tube is arranged inside the device body, a plurality of drug outlet holes are arranged at the bottom of the disc-shaped tube, the disc-shaped tube is connected to the inner wall of the device body through a fixing plate, and the disc-shaped tube is located above the stirring paddle. The arrangement of the disc-shaped tube can make the drug addition more uniform, speed up the mixing speed of the wastewater and the drug solution, and thus improve the efficiency of wastewater treatment.

[0009] As a further improvement of the utility model, the disc-shaped tube includes a plurality of concentrically arranged annular tubes, and a plurality of connecting tubes are connected between two adjacent annular tubes.

[0010] As a further improvement of the utility model, it also includes a scraper, which is slidably arranged on the filter plate, and a pull rod is connected to one side of the scraper. A detachable sealing plate is sealed and connected to the lower end of the device body near the filter plate. A card groove is provided on the inner side of the sealing plate, and the end of the pull rod is stuck in the card groove. When this device is working, the scraper is close to the inner wall of the device body. The scraper and the pull rod are prevented from moving back and forth through the action of the sealing plate card groove. When the filter plate needs to be cleaned, the sealing plate is opened, and the filter plate can be cleaned by operating the pull rod to drive the scraper to move along the filter plate.

[0011] As a further improvement of the utility model, the scraper is an arc-shaped plate.

[0012] The beneficial effects of the utility model are: the utility model can accelerate the mixing of the liquid medicine and the wastewater, has high sedimentation efficiency, has good water treatment effect, and is convenient for cleaning the filter plate. When in use, the wastewater after sedimentation in the sedimentation tank enters the main body of the device through the water inlet pipe, and the liquid medicine is added to the wastewater through the dosing pipe. By accelerating the mixing speed of the wastewater and the liquid medicine, the treated clean water is transported to the clean water tank through the water outlet pipe, and the treated clean water can be used for site flushing, concrete mixing, spraying dust reduction, etc. BRIEF DESCRIPTION OF THE DRAWINGS
