Description

The quick processing equipment of bio-waste
Technical field
The present invention relates to technical field of environment protection equipment, refers in particular to the quick processing equipment of bio-waste.
Background technology
Traditional economy life style produces substantial amounts of bio-waste(Biowaste), as agricultural crop straw, forest remain Thing, livestock-raising excrement slurries, bio-based all kinds of organic wastes of industry and municipal refuse etc., biological waste object amount is big, it is wide, point Dissipate, the bio-waste handling process difference that cost recovery is high, different, processing cost remains high.
By taking the processing of livestock-raising excrement therein as an example, one of existing processing method is by it by way of fermentation Organic fertilizer is processed into, further effectively to utilize.Fermentation method is compost to organic fertilizer earlier, and the organic matter in compost is micro- Complex transformations are carried out under biological agent, the conversion process is:One, the mineralization process of organic matter, the organic matter decomposition of complexity For simple material, carbon dioxide, water and mineral nutrient etc. are ultimately produced;Two, the humification process of organic matter, organic matter is through dividing Solution synthesizes again, generates humus.
Wherein, the mineralization process of organic matter, the energy is provided for microbial activities, and it is accurate for the humification of compost organic matter Standby base stock.Compost with aerobic microorganism activity for it is main when, organic matter rapid mineralization generate more carbon dioxide, water and Other Nutrients, decomposition rate is fast and thorough, and releases a large amount of heat energy;With anaerobe activity for it is main when, organic matter Decomposition rate it is slow, and not thoroughly, release heat energy is few, and its catabolite easily accumulates organic acid and CH in addition to plant nutrient4、H2S、 PH3、H2Deng reducing substances.The humification process of organic matter, it can substantially be divided into two stages:First, Organic residues decomposing shape is in groups Into the original material of humus molecule, such as polyhydric phenols, itrogenous organic substance(Amino acid, peptide etc.)Deng;2nd, first by microorganism secretion Polyphenol oxidase is formed humus monomer by polyphenol oxidase into quinone, then quinone and the condensation of amino acid or peptide.
Composting process has many different types of microorganisms to participate in.Due to the change of raw material and condition, various microorganisms Quantity is also constantly changing, and each environment has its specific microorganism species.Composting process is mainly by microorganism Effect is carried out, and microorganism has two sources:First, original microorganism in organic fertilizer;Another is the microbial inoculant manually added Agent.
The compost fermentation mode of organic fertilizer needs damp condition, aeration condition and microorganism to produce suitable temperature, so And there is following defect in the compost fermentation mode of the organic fertilizer of prior art:
One, the compost fermentation mode of organic fertilizer, its microorganism species mix uneven, and initial effective microbe with organic fertilizer The ratio of biomass and excrement is too low, while faces the competition of other microbial strains, antagonism, therefore its breeding is to enough The overlong time of quantity, largely effect on the production efficiency of organic fertilizer fermentation.
Two, fermentation temperature is difficult to control, and is determined completely by damp condition, aeration condition and microorganism, organic so as to influence The production efficiency of fertilizer fermentation.
Three, the damp condition of fermentation is difficult to control, so as to influence the production efficiency of organic fertilizer fermentation.
Four, because organic fertilizer peculiar smell is heavier, the amount of organic fertilizer is estimated generally according to experience, and without accurate measurement, make The amount for obtaining microbial inoculant addition and organic fertilizer mismatches, and influences the production efficiency of machine fertilizer fermentation.
In view of this, the present invention develops the quick processing equipment of bio-waste for overcoming the defect, thus this case is produced It is raw.
The content of the invention
