[0079] Working principle of the present invention:

[0080] First, the sterilizing powder is loaded into the inner cavity of the feeding box 6, and then the air supply pipe 7 is connected to the air inlet box 32. After the liquid flows through the inner cavity of the pipeline 1, the second groove portion 514 can collect water through the special-shaped structure of the water retaining block 511, and the rotating rod 22 can rotate stably through the setting of the rotating paddle 23, which is convenient for driving the fan blade 33, so that the gas in the air supply pipe 7 can pass through the air inlet pipe 34 into the inner cavity of the insertion pipe 55, so that the gas can contact and process the liquid in the pipeline 1;

[0081] At the same time, the turntable 311 rotates, driving the movable block 313 to swing, so that the pull rod 315 at the end of the connecting rod 314 can pull the connecting rod 544, so that the support 543 can swing, and the flexibility of the first canvas tube 547 and the second canvas tube 548 can ensure that the swing of the support 543 is not affected, so that the powder in the inner cavity of the feeding box 6 can enter the top of the support 543 respectively, and the powder can enter the inner cavity of the two feeding tubes 545 respectively. The baffle 546 is set to prevent the powder in the inner cavity of the feeding tube 545 from falling randomly, thereby reducing unnecessary large-scale loss of powder, and the weight of the baffle 546 is sufficient to prevent the powder from falling randomly. The force and the swing of the feeding tube 545 facilitate the feeding of powder in portions, facilitate the interval feeding of medicine powder, reduce the direct feeding of medicine powder, and enable the powder to sterilize the water flowing in the pipeline 1. The gas in the inner cavity of the air inlet pipe 34 can blow the powder to discharge, so that the powder can contact with the liquid in the pipeline 1 in a large area, thereby improving the sterilization effect of the medicine powder. At the same time, the second groove part 514 can gather water, accelerate the mixing efficiency of the fallen medicine powder and the liquid in the pipeline 1, and facilitate the rotating paddle 23 to mix and stir the medicine powder again, reduce the precipitation and accumulation of medicine powder in the pipeline 1, and improve the stability of the dosing of landfill leachate;

[0082] Secondly, the swing of the support 543 allows the ball 541 to roll in the inner cavity of the ball groove 512, so that the magnetic block 542 drives the magnetic card block 533 to swing, thereby reducing the splashing of the leachate onto the ultraviolet lamp 532, and realizing the ultraviolet lamp 532 to quickly and deeply sterilize the liquid. The structure is simple and the engineering workload is small, which improves the convenience of pretreatment in the deep treatment of garbage leachate.
