Embodiment 1
[0039] The present embodiment 1 provides a process for resource utilization of end vegetables in farmers' markets, comprising the following steps:
[0040] S1: Collect the end vegetables in the farmer's market, clean them and sterilize them at high temperature;
[0041] S2: breaking the sterilized tail vegetables into fragments or paste, dehydrating, and heating and drying; grinding the dried tail vegetables into powder, and fully stirring evenly;
[0042] S3: Add the powder into the biogas fermentation tank, add water and stir to form a paste, add fermentation bacteria, and ferment to produce biogas; the fermentation process includes 1 low-aerobic fermentation and 3 to 4 anaerobic fermentations;
[0043] S4: After the fermentation is finished, the remaining biogas residue is used as the bottom material to make organic fertilizer.
Embodiment 2
[0045] On the basis of Example 1, this Example 2 provides a process for resource utilization of end vegetables in farmers' markets. This Example 2 further defines the specific method for producing biogas with powder as follows:
[0046] S3.1: Add the powder into the biogas fermentation tank, add 25% of the powder weight in sterilized water, and fully stir it into a paste;
[0047] S3.2: Add fermented strain I suspension with 4% volume of sterilized water into the biogas fermenter and stir evenly; the concentration of fermented strain I is 10 7 Individual / mL, including Saccharomyces cerevisiae and Bacteroides succinogenes with a ratio of 1:2;
[0048] S3.3: Seal the biogas fermentation tank, fill it with mixed gas I with an oxygen content lower than that of air, and discharge the original air in the biogas fermentation tank at the same time, and incubate at 28°C for 72 hours; the composition of mixed gas I is as follows: O 2 Content 10%, H2 Content 1% and N 2 Content 89%;

Embodiment 3
[0052] This embodiment 3 provides a kind of end vegetable resource utilization process on the basis of embodiment 2. This embodiment 3 further defines the specific method for producing biogas with powder as follows:
[0053] S3.1: Add the powder into the biogas fermenter, add 50% of the weight of the powder in sterilized water, and fully stir it into a paste;
[0054] S3.2: Add fermented strain I suspension with sterilized water volume of 8% to the biogas fermenter, and stir evenly; the concentration of fermented strain I is 10 7 Individual / mL, including Trichoderma viridans and Butyrivibrio fibrinolyticus with a quantity ratio of 3:2;
[0055] S3.3: Seal the biogas fermentation tank, fill it with mixed gas I with an oxygen content lower than that of air, and discharge the original air in the biogas fermentation tank at the same time, and incubate at 35°C for 48 hours; the composition of mixed gas I is as follows: O 2 Content 10%, H 2 Content 1% and N 2 Content 89%;
