Comprehensive treatment system and treatment method for whole fermentation reduction process of kitchen waste anaerobic tower

Abstract

The invention discloses comprehensive treatment method for the whole fermentation reduction process of a kitchen waste anaerobic tower. The comprehensive treatment method comprises the following steps: 1, pretreating kitchen waste to obtain a waste material to be fermented; 2, mixing and blending the waste material sewage finally obtained in the step 1, and pumping the uniformly mixed sewage intoan anaerobic reactor through a lifting pump, and performing anaerobic fermentation for 5-25 days; 3, storing a large amount of biogas generated every day in the anaerobic process in the step 2, desulfurizing the biogas, feeding the desulfurized biogas into a biogas comprehensive utilization unit, and flowing the generated biogas slurry into a liquid storage pool; and 4, passing one part of the biogas slurry generated in the step 3 through a filtering system for a farmland drip irrigation system, and feeding the other part of the biogas slurry into a subsequent advanced treatment system. According to the comprehensive treatment method, kitchen waste can be effectively collected and treated, the waste is turned into available biogas and biogas slurry, waste is turned into wealth, and the burden of the waste on the environment is reduced.

Description

technical field [0001] The invention belongs to the technical field related to the comprehensive treatment of kitchen waste reduction, and in particular relates to a comprehensive treatment system and a treatment method for the whole process of kitchen waste anaerobic tower fermentation reduction. Background technique [0002] The pretreatment of kitchen waste adopts the process of "unloading + coarse crushing + magnetic separation + large debris screening". Ozone gas passes through the disinfection pipe network set in the silo, and fully contacts with the garbage, so that harmful bacteria such as E. coli in the garbage can be inhibited or killed, thereby increasing the risk of bacterial infection of the operator. The sterilized garbage is transported by the double-screw conveyor It is transported to the crusher for crushing, the drained part enters the desanding unit, the kitchen waste is unloaded and crushed, and enters the magnetic separation unit to separate metal substa...
