Abstract
The invention discloses a kind of methods for improving biogas output to promote electronics to transmit from electricity production bacterium to methane phase archaeal, to realize the methane production for greatly improving methane-generating pit by adding conductive carrier in methane-generating pit;And it adds metal component or is once put into using all-metal methane-generating pit and achieve that permanent use.
Description
Technical field
The invention belongs to biomass energy technology fields, and in particular to a method of improve biogas output.
Background technique
Using methane-generating pit by agricultural wastes(Feces of livestock and poultry and stalk)Being converted to for the methane of burning is China's many
The common way in rural area.The methods for reporting some raising methane-generating pit methane productions at present, including fermentation raw material pretreatment,
Adjust pH value, addition mixed bacteria, adjust carbon-nitrogen ratio etc., these methods usually require additionally to add various substances, not only increase
Add economic cost, and cumbersome, time and effort consuming increases labour cost.
Contain a large amount of anaerobic bacterias in biogas slurry, including the electronics of generation intracellular can be discharged into extracellular electricity production bacterium
(Such asClostridium spp、ShewanellaSpp etc.), and from it is extracellular receive electronics and synthesizing methane there is electrification
Learn active methane phase archaeal(Such asMethanobacteriumSpp etc.).If electronics can be promoted from bacterium is produced electricity to production first
The transmitting of alkane archaeal, it will be able to promote the formation of methane, to realize low cost, low consumed raising methane production.
Summary of the invention
The technical issues of solution:In order to greatly improve the methane production of methane-generating pit, increase energy resource supply, the present invention provides one
The method that kind improves biogas output promotes electronics ancient from electricity production bacterium to methane phase by adding conductive carrier in methane-generating pit
Bacterium transmitting, to improve the yield of methane.
Technical solution:
A method of biogas output is improved, conductive carrier is added in methane-generating pit, promotes electronics from bacterium is produced electricity to methane phase
Archaeal transmitting.
Further, it is by adding metal on traditional bamboo-woven concrete inner wall that conductive carrier is added in methane-generating pit
Component is realized using all-metal methane-generating pit.
Further, the shape of the metal component is netted, sheet or rodlike.
Further, the material of the metal component is stainless steel, aluminium alloy, titanium or copper.
Further, the material of the metal methane-generating pit is stainless steel, aluminium alloy, titanium or copper.
Further, the metal component is fixed on traditional bamboo-woven concrete inner wall, and submerges below the liquid level of biogas slurry.
Beneficial effect:The present invention promotes electronics from bacterium is produced electricity to methane phase by adding conductive carrier in methane-generating pit
Archaeal transmitting, to realize the methane production for greatly improving methane-generating pit;And it adds metal component or uses all-metal methane-generating pit
Primary investment achieves that permanent use.
Detailed description of the invention
Fig. 1 is to add the schematic diagram of metal component in methane-generating pit in embodiment 1,1 is methane-generating pit inner wall, 2 is metal structure
Part, 3 are setscrew.
Fig. 2 is the methane emission comparing result of three kinds of methane-generating pits in embodiment 1.
Specific embodiment
Following embodiment further illustrates the contents of the present invention, but should not be construed as limiting the invention.Without departing substantially from
In the case where spirit of that invention and essence, to modification made by the method for the present invention, step or condition and replaces, belong to the present invention
Range.Unless otherwise specified, the conventional means that technological means used in embodiment is well known to those skilled in the art.
Embodiment 1
The present invention provides a kind of methods for improving biogas output, construct Miniature biomass pool in laboratory(Diameter 15cm is high
20cm), wherein methane-generating pit A is all steel material;Methane-generating pit B is plastic material, and inner wall installs stainless (steel) wire additional, as shown in Figure 1,
Fixed metal component 2 is installed using setscrew 3 on plastic methane tank inner wall 1;Methane-generating pit C is plastic material, and withouyt
Any metal component.It is separately added into the mixture of 160 g fresh chicken manures and 80 g rice straw powder in methane-generating pit A, B, C and waterflooding is kept
Anaerobic environment.It collects the gas that methane-generating pit discharges in 1 hour respectively with gas production cover within every 2 days later, is analyzed using chromatography of gases
The accumulation discharge amount of methane.As a result as shown in Fig. 2, the 2nd, 4,6,8 day methane emission is all methane-generating pit A after operation methane-generating pit
>B>C.Methane emission compared to methane-generating pit C, A and B increases separately 100% and 50% or so.The result shows that installing stainless steel additional
Net and methane emission can be greatly improved using all steel methane-generating pit.
