Abstract

The present invention relates to a food waste composting pre-treatment method, which comprises that: 1) food waste is fed, wherein food waste is poured onto a chain plate bag-breaking conveying integration machine through a special food waste transporter; 2) a roller bag-breaking device is arranged on the head section of the chain plate bag-breaking conveying integration machine to cut a big bag in materials so as to carry out preliminary bag breaking; 3) the food waste being subjected to preliminary solid-liquid separation and bag breaking is conveyed to a drum sieve through a chain belt conveyor to carry out screening; 4) the undersize material enters a pressing dewatering device through a screw conveyor; 5) the pressed and dewatered food waste is conveyed to a uniform material distribution garbage bin through the screw conveyor; and 6) the oversize material is discharged into a compressible garbage bin through the oversize material outlet of the drum sieve. The food waste composting pre-treatment method is mainly used for carrying out bag breaking, water filtration, screening and pressing dewatering on food waste so as to meet composting process requirements and improve composting effect.

Description

technical field

[0001] The invention belongs to the field of garbage treatment, and in particular relates to a method for composting pretreatment of kitchen garbage. Background technique

[0002] Kitchen waste, commonly known as swill, is the domestic waste formed by residents in the process of living consumption. The content of perishable organic matter in food waste is 40%-50%, mainly including kitchen waste, catering industry waste, food industry tailings, etc., mainly starch, food fiber, animal fat and other substances, with High moisture content, high oil and salt content, easy to rot, ferment, and stink.

[0003] The perishable organic matter in food waste has high moisture and oil content. If it is incinerated with other domestic waste, the heat energy utilization of incineration will be greatly reduced. At the same time, the lipids in it will become an important factor for the production of dioxins under the catalytic conditions of heavy metals; and Landfill treatm...
