Example Embodiment
[0017] Example 1
[0018] Step 1: Separate the paper, chopsticks, toothpicks and plastics from the kitchen waste, filter, pulverize and dry to make the particle fineness 30 mesh and the organic dry matter content ≧50%;
[0019] Step 2: adding 15% soybean flour and 20% rice bran to the pretreated kitchen waste in step 1, stirring evenly, and sterilizing with high pressure steam at 121° C. for 20 minutes to obtain a fermentation substrate;
[0020] Step 3: At 28°C, inoculate 2 parts of Bifidobacterium, 6 parts of Lactobacillus, 3 parts of Bifidobacterium and 5 parts of yeast in a liquid medium with a pH of 6.2, at a temperature of 10 m 3 Introduce sterile air at a flow rate of / h, and after culturing for 2 days, concentrate and purify to prepare a compound inoculum. Every 3h, stirring at a rate of 60r / min for 20min, after fermentation for 20h, the crude feed was obtained;
[0021] Step 4: After mixing 20 parts of berberine hydrogen sulfate, 12 parts of allicin, 18 parts of alo...
