Embodiment 1

[0037] According to the weight ratio of 10:0.5, take 1 ton of kitchen waste and 50kg of straw, filter the kitchen waste, remove water and oil, and then crush the straw, and mix them well; add water, adjust The humidity is 60%; add citric acid at room temperature to adjust the PH value of the mixed material to 4.5; take cellulase, hemicellulase, Xylanase, arabinase, β-glucanase and glucoamylase are mixed to obtain a broken-wall enzyme preparation; according to the ratio of the total amount of active units of the broken-wall enzyme preparation: the total amount of straw powder is 6FPU / g, Take broken enzyme preparation 3×10 5 Add FPU to the mixed material and stir evenly; after stirring for 15 minutes, add sodium carbonate-sodium bicarbonate buffer solution with a pH of 10, adjust the pH of the mixture to 7.5, and terminate the enzyme-catalyzed reaction; at room temperature, according to the concentration ratio of 1.2:1: 0:0.6 Streptococcus faecalis, Acetobacter, yeast and Lacto...

Embodiment 2

[0039] Take 1 ton of cattle farm waste (including feces, urine and cattle carcass) and 100 kg of straw according to a weight ratio of 10:1, grind the two materials respectively and mix them evenly; add water and adjust the humidity to 70%; at room temperature Add sodium citrate and malic acid to adjust the pH value of the mixed material to 5.0; according to the total amount of active units of the broken enzyme preparation: the ratio of the total amount of straw powder to 6FPU / g, take 6×10 at room temperature 5 The cellulase of FPU was added to the mixed material and stirred evenly; after stirring for 17 minutes, sodium carbonate-sodium bicarbonate buffer solution with a pH of 10 was added to adjust the pH of the mixture to 8.0 to terminate the enzyme-catalyzed reaction and form a suitable microecological preparation to play a biological role. Active alkaline environment; the concentration of probiotics added to the mixed material is 6.8×10 3 cfu / ml, take 7.48×10 at room temper...

Embodiment 3

[0041] Take 1 ton of chicken farm waste (comprising excrement, urine and chicken carcasses) and 200 kg of straw according to a weight ratio of 10:2, grind the two materials respectively and mix them evenly; add water, and adjust the humidity to 80%; Add tartaric acid under low temperature to adjust the pH value of the mixed material to 5.5; take cellulase, hemicellulase, xylanase, and arabinan at room temperature according to the enzyme activity unit ratio of 6:6:5.6:2.6:0.8:7 Enzyme, β-glucanase and glucoamylase are mixed to obtain a broken-wall enzyme preparation; according to the ratio of the total amount of activity units of the broken-wall enzyme preparation: the total amount of straw powder is 6FPU / g, take the broken-wall enzyme preparation 12×10 5 Add FPU to the mixed material and stir evenly; after stirring for 20 minutes, add sodium carbonate-sodium bicarbonate buffer solution with a pH of 10, adjust the pH of the mixture to 8.5, and terminate the enzyme-catalyzed reac...

Abstract

The invention discloses a method for recycling organic waste by using hermetia illucens. The method comprises the following steps: a, respectively crushing the organic waste and the straws, stirring and uniformly mixing to obtain a mixed material; b, adding water into the mixed material, and adjusting the humidity of the mixed material; and c, adding acidic liquid into the mixed material at room temperature, and adjusting the pH value of the mixed material; and d, adding a wall-breaking enzyme preparation into the mixed material at room temperature, and stirring; e, adding an alkaline liquid into the fully reacted mixed material at room temperature, and adjusting the pH value of the mixed material; f, adding a micro-ecological preparation into the mixed material at room temperature, and stirring; g, inoculating the fully reacted mixed material with the hermetia illucens eggs. According to the invention, the organic waste is pretreated by utilizing the wall-breaking enzyme and the micro-ecological preparation, the treated organic waste is more easily decomposed and utilized by the hermetia illucens, so that the larva yield of the hermetia illucens is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of organic waste treatment, in particular to a method for recycling organic waste by utilizing black soldier flies. Background technique [0002] Food waste, excrement from animal farms and animal carcasses are all very common organic waste in people's daily life. These organic wastes pollute the environment and affect the appearance of the city. Because it contains high organic matter and moisture, it is susceptible to the action of microorganisms, resulting in decay and deterioration; and the longer it is discarded, the more serious the deterioration will be. Especially in summer, when the temperature is higher, the rot and deterioration will be faster. At this time, a large amount of percolation water and malodorous gas are likely to be produced, breeding mosquitoes, and causing adverse effects on environmental sanitation. The seepage generated when organic waste is piled up enters the sewage treatment ...
