Embodiment 1

[0039] The present embodiment 1 provides a new resource utilization process of end vegetables in farmers' market, 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 new resource utilization process for end vegetables in farmers' markets. This Example 2 further defines the specific method for producing biogas from 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 fermentation tank, 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 2Content 10%, H 2 Content 1% and N 2 Conte...

Embodiment 3

[0052] On the basis of Example 2, this Example 3 provides a new resource utilization process for end vegetables in farmers' markets. This Example 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...

Abstract

The invention provides a novel resource utilization process for waste vegetables in a farmers' market. In the process: marsh gas is prepared utilizing waste vegetables in a farmers' market, preservingwastes are turned into wealth, thereby providing high-quality energy. The preparation process of marsh gas comprises primary aerobic fermentation and multi-time anaerobic fermentation, low aerobic fermentation is used for decomposing macromolecule substances to provide enough nutrition for the next anaerobic fermentation, thereby both ensuring smooth proceeding of strain culture and fermentationand avoiding excessive O2 residue to influence the physiological activity of subsequent anaerobic fermentation of strains; anaerobic fermentation is performed in many times, fermentation backing materials are updated at regular intervals, thallus quantity in a fermentation system is controlled, and continuous proliferation updating of thallus. After the fermentation of marsh gas is ended, waste vegetable marsh residues are used to prepare organic fertilizer, and thus wastes are further turned into high-quality fertilizer. The method can sufficiently utilize collected waste vegetable resources,and the utilization rate of the waste vegetable resources is maximized.

Description

technical field [0001] The invention belongs to the technical field of resource utilization of tail vegetables, and in particular relates to a novel resource utilization process of tail vegetables in farmers' markets. Background technique [0002] With the development of economy and science and technology, people's living standards have been significantly improved. Due to the great abundance of living materials, people began to gradually pursue the quality of life. One of the most intuitive manifestations is the increase in food requirements. There is no need to be stingy with stale or poor-looking ingredients, and they can be easily discarded. As a result, a large number of discarded end vegetables appear every day in fresh product sales places led by farmers' markets. These end vegetables themselves are plant components, rich in various organic substances and inorganic salts, and it is a pity to discard them directly. In addition, if these end vegetables are piled up rand...
