Abstract
The invention discloses an alfalfa anaerobic fermentation production process which mainly comprises acidification pretreatment, anaerobic heat preservation and inoculation fermentation. The alfalfa anaerobic fermentation production process provided by the invention comprises the steps: carrying out acid pretreatment, then carrying out heat preservation, finally inoculating under a condition of the temperature of 45-55 DEG C, carrying out biogas fermentation, and thus obtaining biogas with the maximum amount; the biogas can be used for heat and gas supplying for places around a farm, and produced biogas slurry and biogas residues can be directly used as crop fertilizers, so that the use amount of chemical fertilizers and pesticides is reduced, environmental pollution is reduced, and at the same time, pollution-free agricultural production is promoted.
Description
Technical field
The invention belongs to technical field of anaerobic fermentation, more specifically, more particularly to a kind of Alfalfa anaerobic fermentation is produced
Technique.
Background technology
Increasingly serious with rural environmental pollution and energy shortage problem, the development of household biogas is by the extensive of people
Concern, becomes the main contents of important component and the rural energy development of China's new countryside construction.Devoting Major Efforts To Developing is biological
Mass-energy source, anaerobic fermentation production biogas is carried out using agricultural wastes, is to solve fuel in China's rural areas anxiety to be asked with environmental pollution
The key of topic.
In the long-term plant development Alfalfa in Anhui Wuhe County farm, the farm is after the Alfalfa after ensiling or harvesting
Alfalfa transport it is edible for milk cow etc. to each herding grass, but during Alfalfa Silage grass or harvesting Alfalfa,
Often having many Alfalfas for going mouldy can not utilize, and be discarded in around farm, not only waste of resource, and pollution environment,
Accordingly, it would be desirable to be used discarded Alfalfa is abandoned.
Comparative analysis of the present invention household biogas and big-and-middle-sized biogas engineering China rural area applicability, and for because of rule
The problem of the household biogas fermentation raw material deficiency that modelling cultivation is caused instead of the pattern of raising scattered, it is proposed that lucerne is improved by biochemical treatment
The method of Mu marsh gasification utilization ratio, obtains optimal optimize technique, improves fermentation efficiency, shortens fermentation time.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of Alfalfa anaerobic fermentation for proposing
Production technology.
To achieve the above object, the present invention provides following technical scheme：
A kind of Alfalfa anaerobic fermentation production technology, comprises the following steps：
Stack retting is carried out under S1, the corrupt discarded Alfalfa anaerobic condition for feeding value without food that will go mouldy to process 10-20 days；
S2, the acid solution that will have been configured are according to discarded Alfalfa and solution 3：1 mass ratio is added in every part of discarded clover
In grass and stir, make the water content of mixture in 72-78%；
S3, will mix discarded Alfalfa plastic film seal, at room temperature 18-22 DEG C of standing pre-processed within 7 days, place
Discarded Alfalfa after reason carries out biogas fermentation under the conditions of 45-55 DEG C.
Preferably, in S2, the acid solution is hydrochloric acid solution or acetum or hydrogen peroxide.
Preferably, in S3, it is inoculated with the discarded Alfalfa after treatment, is mixed according to 200g inoculums and 550g fermentation raw materials
Close, fermented.
Technique effect of the invention and advantage：A kind of Alfalfa anaerobic fermentation production technology that the present invention is provided, by acid
Pretreatment, is then incubated, and finally inoculation carries out biogas fermentation under the conditions of 45-55 DEG C, obtains the maximum amount of biogas, and the biogas can
Think that the heating supply of the place around farm is used, the biogas slurry and biogas residue of generation can be directly as Crop fertilizers, so as to subtract
Lack the usage amount of chemical fertilizer, agricultural chemicals, while reducing environmental pollution, also promote pollution-less agriculture production.
