Description

Technical Field

[0001] The invention relates to the technical field of landfill leachate treatment, in particular to a landfill leachate treatment device and a treatment process thereof. Background Art

[0002] Leachate is a high-concentration organic wastewater produced in landfills or waste treatment facilities. It contains a variety of harmful substances and will cause serious pollution to the environment if not properly treated. Leachate treatment usually requires flocculants, which are chemical substances used to promote the aggregation of suspended particles in water to form larger flocs (flocs). These flocs can then be separated from the water by sedimentation or flotation. However, in the prior art, flocculants are generally added directly to the filtrate, which will result in uneven dispersion of the flocculants. The uneven distribution of flocculants will cause the flocs to be of different sizes, loose in structure, and difficult to settle, which will affect the stability and sedimentation rate of the flocs, resulting in a decrease in the treatment efficiency of the entire system.

8. The garbage leachate treatment device according to claim 1, characterized in that: The cleaning assembly (6) comprises a fixed motor (61), a bidirectional threaded rod (62), a moving block (63), a connecting guide rod (64), a connecting long tube (65), bristles (66), a water outlet nozzle (67) and a fixed frame (68); the upper end of the fixed frame (68) is fixedly mounted on the lower end of the supporting guide tube (97); the lower end of the fixed frame (68) is fixedly connected to the supporting main rod (5); the fixed motor (61) is fixedly mounted on the fixed frame (68); the output end of the fixed motor (61) is fixedly connected to the upper end of the bidirectional threaded rod (62); and the bidirectional threaded rod (62) is rotatably mounted inside the supporting main rod (5).

9. The garbage leachate treatment device according to claim 8, characterized in that: The supporting main rod (5) is provided with a groove for the moving block (63) to slide, the moving block (63) is threadedly connected to the bidirectional threaded rod (62), one end of the connecting guide rod (64) is hinged to the moving block (63), the other end of the connecting guide rod (64) is hinged to the connecting long tube (65), the connecting long tube (65) is connected to the elastic conduit (99), one end of the connecting long tube (65) is fixedly connected to a plurality of bristles (66), and one end of the connecting long tube (65) is connected to a plurality of water outlet nozzles (67).

10. A landfill leachate treatment process, characterized in that: The landfill leachate treatment device according to any one of claims 1 to 9 comprises the following steps: Step 1: Add the leachate into the cylinder (1), add the flocculant into the liquid storage tank (17), start the driving motor (12) to rotate the supporting main rod (5), and during this process, the flocculant is evenly sprayed out through the liquid separation component (9); Step 2: During the process of spraying the flocculant, the inner teeth (101) move to drive the driving gear (103) to rotate, thereby driving the plurality of mounting sleeves (105) and the dispersion plate (106) to rotate, further accelerating the diffusion of the flocculant, so that the flocculant is evenly dispersed; Step 3: After the reaction is completed, the valve (4) is opened, and the solution flows out from the liquid outlet pipe (3).
