Method for deodorization and sterilization of garbage dump

Abstract

The invention belongs to the technical field of garbage treatment, and discloses a method for deodorization and sterilization of a garbage dump, and the problem that large-scale treatment of garbage is not facilitated due to long sterilization time of ultraviolet rays can be solved. Garbage is firstly crushed through a first crushing cavity and then enters a first sterilization chamber to be sterilized through alkaline electrolyzed water; and then the garbage is conveyed to a second crushing cavity through a lifting cavity to be crushed again, and then enters a second sterilization chamber to be sterilized through acidic electrolyzed water. Through the combined action of acidic electrolyzed water and alkaline electrolyzed water, germs and bacteria in the garbage can be thoroughly killed, materials can be continuously overturned and stirred through the action of a spiral conveying roller and a discharging spiral roller when the garbage is in the first sterilization chamber and the second sterilization chamber, and the alkaline electrolyzed water and the acidic electrolyzed water are sprayed through nozzles, so that the dispersion uniformity of the electrolyzed water can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of garbage disposal, and in particular relates to a method for deodorizing and sterilizing garbage dumps. Background technique [0002] Due to the various types of garbage contained in the garbage dump, the garbage dump has a very strong odor, and in order to avoid the infection of germs and bacteria, it is necessary to sterilize the garbage. [0003] At present, there are roughly two types of disinfection and sterilization methods for garbage, one is ultraviolet sterilization, and the other is high-temperature sterilization. The two sterilization methods have their own advantages and disadvantages. Ultraviolet sterilization has the characteristics of strong bactericidal effect, but the penetration ability of ultraviolet rays is weak. Due to the poor penetration, it takes a long time for sterilization, which is not conducive to large-scale treatment of garbage; Sterilization consumes more energy. Contents...
