Abstract
Description
Technical Field
[0001] The invention relates to the technical field of landfill leachate treatment, in particular to landfill leachate treatment equipment. Background Art
[0002] Landfill leachate is a highly concentrated organic wastewater formed by the water contained in the landfill itself, rainwater, snow, and other water that enters the landfill, minus the saturated water holding capacity of the landfill and the overburden, and then passing through the landfill and overburden layers. There is also water that leaks from accumulated garbage destined for incineration.
[0003] In the prior art, a motor provides power to rotate the shaft, which drives the chassis and blades to rotate to mix the flocculant and the landfill leachate evenly.

[0030] During the implementation of the present invention, the treatment agent is first added into the medicine storage box mechanism 6. At this time, the height of the medicine storage box mechanism 6 is adjusted according to the type and state of the landfill leachate, and the relative positions of the medicine storage box mechanism 6 and the rotating medicine guiding mechanism 8 are controlled. At this time, the landfill leachate enters the treatment box 1 through the liquid inlet 3, and the landfill leachate enters the mixing barrel mechanism 7 in the treatment box 1. Due to the presence of the one-way rotation limiting mechanism 9, the rotating medicine guiding mechanism 8 can be rotated unidirectionally, and the rotating medicine guiding mechanism 8 can guide the medicine in the medicine storage box mechanism 6 into the mixing barrel mechanism 7. The greater the flow rate of the landfill leachate, the faster the rotation speed of the rotating medicine guiding mechanism 8, and the greater the discharge amount, thereby realizing adaptive discharge of the medicine. Under the scraping of the first scraper 10, the material above the mixing barrel mechanism 7 can be scraped into the mixing barrel mechanism 7, and finally the material enters the bottom of the treatment box 1. Under the treatment of the bottom treatment mechanism 11, the deposited debris can be discharged regularly, and the treated landfill leachate is discharged through the liquid outlet 4.
