When the connecting block 33 reciprocates, the rotating shaft 24 which is rotationally connected to the connecting block 33 synchronously reciprocates along with the connecting block 33, at the moment, the gear 25 which is fixedly connected to the side wall of the rotating shaft 24 is meshed with the rack 35 and rotates, and the rotating shaft 24 is driven to rotate, so that the stirring rod 26 at the bottom of the rotating shaft 24 stirs the wastewater in the treatment tank 2, at the moment, the flocculating agent is put into the treatment tank 2 through the through groove 22, and the stirring rod 26 is matched with the stirring of the wastewater in the treatment tank 2, so that harmful substances in the wastewater are flocculated and settled.
After entering the liquid level Gao Yuna filter membrane 41 of the wastewater in the treatment tank 2, the wastewater spontaneously flows out into the recovery tank 4 after being filtered by the nanofiltration membrane 41, and at this time, the recovery tank 4 recovers the water filtered by the nanofiltration membrane 41, and the recovered water is recycled.
When the flocculate in the treatment tank 2 reaches the upper part of the nanofiltration membrane 41, the water pump 12 is turned off, and the first electric telescopic rod 51 is controlled to be contracted first, so that the blocking plate 52 is separated from contact with the treatment tank 2, and the wastewater after flocculation sedimentation treatment in the treatment tank 2 is discharged into the containing tank 5.
The arrangement of the filter screen 53 enables the flocculate to be separated so that it does not enter the holding tank 5 and is started, and the gap between the filter screen 53 and the bottom wall of the treatment tank 2 enables the wastewater after flocculation sedimentation treatment to be discharged with less residue in the treatment tank 2.
The side part of the treatment box 2 is prolonged by the arrangement of the discharge cylinder 56, the sliding seat 57 at the end part of the discharge cylinder 56 enables the stop door 58 to slide vertically, and when the wastewater level in the treatment box 2 is started to be lowered to the lower part of the filter screen 53, the second electric telescopic rod 59 is controlled to extend, so that the stop door 58 is lifted, and at the moment, flocculate in the treatment box 2 can be discharged.
The electric slide block 55 is started, the scraper 54 is controlled to slide towards the direction of the discharge cylinder 56, so that flocculate on the filter screen 53 is pushed out by the scraper 54, then the electric slide block 55 is controlled to drive the scraper 54 to move towards the original position, the stop door 58 is closed, the water pump 12 is started, and the wastewater treatment is continued.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
