Novel landfill leachate treatment device

Abstract

The invention relates to the technical field of landfill leachate treatment. The invention further discloses a novel landfill leachate treatment device which comprises a working box, the top of the working box is fixedly connected with a first motor; the output end of the first motor is fixedly connected with a rotating shaft; and the bottom end of the rotating shaft penetrates through the top ofthe working box and extends into the working box, a plurality of first stirring rods are fixedly connected to the outer circle face of the rotating shaft in a sleeving mode at equal intervals, two sets of water spraying pipes are symmetrically and rotationally connected between the left inner wall and the right inner wall of the working box, and each set comprises two water spraying pipes. According to the landfill leachate treatment device, the problem that in the working process of an existing landfill leachate treatment device, oxygen is directly introduced into mixed liquid through an airinlet pipe laid at the bottom of the device, an oxygen inlet path is fixed, and therefore the landfill leachate treatment efficiency is seriously reduced is solved.

Description

technical field [0001] The invention relates to the technical field of garbage leachate treatment, in particular to a novel garbage leachate treatment device. Background technique [0002] Garbage leachate refers to the moisture contained in the garbage itself in the landfill, the rain and snow water and other moisture entering the landfill, deducting the saturated water holding capacity of the garbage and the covering soil, and passing through the garbage layer and the covering soil. A kind of high-concentration organic wastewater, if it is discharged directly without treatment, it will cause huge pollution to the environment. [0003] Among the existing landfill leachate treatment methods, the method with better effect and large treatment capacity is the activated sludge method. When treating landfill leachate, it is necessary to fully mix the landfill leachate and activated sludge. , and oxygen is introduced into the mixed liquid to enhance the sufficient adsorption of i...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a new type of landfill leachate treatment device, which solves the problem that during the working process of the existing landfill leachate treatment device, oxygen is directly passed through the air intake pipe laid at the bottom of the device. Into the mixed liquid, the entry path of oxygen is fixed, which seriously reduces the efficiency of landfill leachate treatment
