Embodiment 1

[0061] Such as figure 1 As shown, the method for efficiently sorting and extracting fermentable organic matter from domestic waste is based on the premise of the previous sorting treatment Q, and then for the separated miscellaneous organic matter and high-concentration sewage C, the miscellaneous organic matter is the largest after the pre-sorting treatment Q Particle size organic matter, the high-concentration sewage C is sewage containing fine particle organic matter, and the fermentable organic matter D in domestic waste is extracted through three steps of mechanical selection A, manual selection B, and fine particle organic matter collection E And collect and process, and finally get the raw material for making biogas - high-purity fermentable organic matter D.

[0062] Such as figure 2 As shown, in the "bag bag garbage bag breaking and garbage flushing" Q01 in the pre-sorting process Q of the present embodiment, the garbage bag (bag bag garbage) with domestic garbage w...

Abstract

The invention discloses a method and device for efficiently sorting and extracting fermentable organic matter from household garbage. The device comprises a front sorting processing device, a mechanical fine selecting device, a manual fine selecting device and a fine particle organic matter collecting device. The method comprises the following steps of: with front sorting processing as a premise,respectively carrying out mechanical fine selecting, manual fine selecting and fine particle organic matter collecting on mixed organic matter and high-concentration sewage obtained after separation to extract and collect the fermentable organic matter from the household garbage, wherein the fermentable organic matter can be directly used for preparing methane. The method and device disclosed by the invention can be used for extracting the fermentable organic matter from sorted household garbage, namely the raw material used for preparing the methane can be directly supplied to an anaerobic fermentation reactor can be obtained after a series of preprocessing processes are carried out.

Description

Technical field: [0001] The invention relates to the field of domestic waste treatment, in particular to a method and device for sorting and extracting fermentable organic matter from domestic waste. Background technique: [0002] At present, the output and hazards of domestic waste, the current treatment technology and existing problems. [0003] The composition of domestic waste is comprehensively treated for various components, among which biogas fermentation treatment technology is a technology that can simultaneously process waste treatment and produce clean energy, so it can be used as the preferred treatment technology solution for fermentable organic parts. [0004] However, at present, there is no mature and perfect waste classification and collection system in our country. The domestic waste collected by the transport vehicle is a kind of fermentable organic matter (such as kitchen and fruit and vegetable waste), inert organic matter (plastic, rubber, braid, etc.),...
