Through the coordinated operation of the driving motor 25, the sprocket 21, the chain 22 and the pushing plate 23, the floating objects on the surface of the landfill leachate can be continuously and automatically scraped toward the storage bin. Compared with manual cleaning, this automated cleaning method is more efficient, can greatly reduce labor costs and time costs, ensures that the floating objects in the treatment tank 1 can be removed in time, and avoids their accumulation in the tank and affecting subsequent processing procedures, and The floating objects are cleaned up at the same time, and the harmful substances that may be contained in the floating objects are prevented from dissolving again or mixing into the leachate, thereby improving the treatment effect of the entire garbage leachate treatment equipment, and helping the subsequent treatment links to operate more stably and efficiently, and ensuring the final effluent water quality. The sprocket 21 includes a first gear 211 and a second gear 212.
