Abstract
The invention relates to a method for processing kitchen waste by virtue of a microbial technique. The method comprises the following steps: mixing leached kitchen waste with rice husks and a microbial bacterium solution, so as to obtain a mixed material, wherein the mass ratio of the rice husks to the kitchen waste in the mixed material is 1 to 9, the dosage of the microbial bacterium solution is equal to 0.1wt%-0.5wt% of the total amount of the kitchen waste; fermenting the mixed material while stirring for four hours, so as to prepare an organic fertilizer meeting the relevant standards of the organic fertilizer, wherein the stirring number of revolutions is 20 revolutions per minutes, and the stirring manner is as follows: the foreword stirring is performed for 10 minutes, then the stirring is paused for 10 minutes, backward stirring is performed for 10 minutes, and then the stirring is paused for 10 minutes, over and over again. The method has the advantages that the processing cycle is short, 80% of the kitchen waste is reduced within 4 hours, the residue is the organic fertilizer, and various indexes of the organic fertilizer can meet Agriculture industry standards of People's Republic of China; 'three wastes' are avoided in the degrading process, and the environmental friendliness is achieved.
Description
Technical field
The present invention relates to rubbish from cooking degradation technique field, particularly a kind of method utilizing microbial technique process rubbish from cooking.
Background technology
General the referring to of rubbish from cooking does rubbish produced after meal, comprises leftovers, leftovers, dish leaf, pericarp etc.Rubbish from cooking organic content is enriched, and water ratio is high, perishable to go bad, grow mosquitos and flies, brings serious environmental pollution.In addition, rubbish from cooking is unprocessed feeds as feed, and objectionable impurities is accumulated in the tissue such as fat, muscle of pig, and people has eaten after such pork acquires a certain degree, the systemic immune function such as liver, kidney will be caused to decline, serious threat health of human body.Biodegradable organic waste moisture and fat content high, if greatly can reduce the heat energy utilization of burning with domestic garbage mixing burning, in addition, burning insufficiently can produce dioxin, serious threat health of human body; Landfill disposal then can produce a large amount of biogas and percolate, causes secondary pollution to environment.
Summary of the invention
The object of the invention is for above-mentioned existing problems, a kind of method utilizing microbial technique process rubbish from cooking is provided, the method utilizes thermophilic microorganism degraded rubbish from cooking, in aerobic fermentation process, rubbish from cooking is decomposed rapidly, its processing speed is fast, efficiency is high, and in residuum, organic content is high, and reduces environmental pollution.
Technical scheme of the present invention:
Utilize a method for microbial technique process rubbish from cooking, step is as follows:
1) by rubbish from cooking draining, adjustment rubbish from cooking water ratio is not higher than 80%;
2) husk, rubbish from cooking are mixed with microbial inoculum, obtain mixture, in mixture, the mass ratio of husk and rubbish from cooking is 1:9, and the consumption of microbial inoculum is the 0.1-0.5wt % of husk and rubbish from cooking total amount;
3) by mixture temperature be 60 DEG C, water ratio carry out under being 45-65% condition stirring fermentation, agitation revolution is per minute 20 turns, alr mode be rotating forward 10 minutes, pause 10 minutes, reversion 10 minutes, pause within 10 minutes, repeatedly carry out, react after 4 hours, the obtained fertilizer meeting fertilizer relevant criterion (NY515-2012).
Microbial bacteria selected by described microbial inoculum is mixed formed by subtilis, Bacillus licheniformis, Bacillus coagulans, thermophilic pseudomonas and bacillus polymyxa, and the mass ratio of subtilis, Bacillus licheniformis, Bacillus coagulans, thermophilic pseudomonas and bacillus polymyxa is 1-3:2-3:2-4:3-4:1-4; Microbial bacteria spreads cultivation through bacteriolyze meat soup (LB) substratum and obtains microbial inoculum, described bacteriolyze meat soup (LB) substratum is mixed by Tryptones, yeast extraction, sodium-chlor and deionized water and forms, in mixed solution, the concentration of each component is Tryptones 10g/L, yeast extract 5g/L, sodium-chlor 10g/L, and the pH of mixed solution is 7.4; That shaking table cultivates 24 hours at 50-65 DEG C by the method for bacteriolyze meat soup (LB) culture medium culturing microbial bacteria, rotating speed 150rpm.
Advantage of the present invention and beneficial effect are:
This utilizes the method for microbial technique process rubbish from cooking, and treatment cycle is short, and by kitchen waste reductionization 80% in 4h, residuum is fertilizer and indices all can meet People's Republic of China's agricultural industry criteria-organic fertilizer (NY525-2012); Produce without " three wastes " in degradation process, environmental protection.
Accompanying drawing explanation
Fig. 1 is that different microorganisms is to rubbish from cooking ferment effect figure.
