Description
Technical field
The present invention relates to farming and animal husbandry organic waste treatment technical field, more particularly to a kind of excrement and crop
The method of stalk combined ferment comprehensive utilization.
Background technique
According to statistics, the crop material that China generates every year is more than 700,000,000 tons, is equivalent to 3.53 hundred million tons of standard coals.Crop material
It is a kind of renewable resource of preciousness, but for a long time due to being influenced by consumption idea and life style, China rural area straw
Stalk resource does not obtain rational exploitation and utilization.According to investigations, China's straw utilization rate is only about 45% at present, and wherein most does not add
Processing, what is utilized after technical treatment only accounts for about 2.6%.Therefore, comprehensive utilization crop material resource is for economizing on resources, protecting
Retaining ring border increases farmers' income, the sustainable development of agricultural is promoted all to have important practical significance.
Same China is also a livestock and poultry breeding industry big country, generates 3,800,000,000 tons of feces of livestock and poultry every year, be effectively treated rate but less than
50%, if do not dealt carefully with, the stench distributed pollutes water resource nearby, causes to seriously endanger to living environment.
Traditional biogas fermentation material be monocrop stalk or single excrement, but crop stalk fibre element and lignin
Content is higher, and surface have coating of wax matter be unfavorable for microorganism attachment cause its degradation rate is low, anaerobic digestion time is long, easily go out
The problems such as discharging is crusted and is difficult in now floating layering, pond.And the carbon-nitrogen ratio in feces of livestock and poultry is lower, is unfavorable for biogas fermentation.
Therefore, the drawbacks of single stalk or single excrement can effectively being made up as fermentation raw material using excrement and stalk mixed fermentation,
And excrement and stalk be can be only achieved into optimal production gas effect, and the biogas residue of its generation and natural pond with what ratio and method fermentation
Liquid energy high-value-use, reaching good economic benefit also becomes a key factor of research mixed raw material fermentation.
Summary of the invention
In view of this, making excrement the present invention provides a kind of method for comprehensively utilizing excrement and crop material combined ferment
Just biogas, biogas slurry and biogas residue are generated by anaerobic fermentation with crop material, and biogas, biogas slurry and biogas residue is carried out reasonable
It recycles, realizes the purpose that excrement and crop material are turned waste into wealth, while solving rural area combustion gas, heating, organic fertilizer
The problem of source.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of method of excrement and the comprehensive utilization of crop material combined ferment, comprising the following steps:

2) biogas slurry is added to adjust water content to 65~70% pretreated crop material, 24~36h of isothermal pyrolysis；
3) by after above-mentioned pyrolysis crop material and feces of livestock and poultry in 1.5~2:1 ratio be added reactor in, use biogas slurry
Reflux mist spray is carried out to crop material and feces of livestock and poultry mixed material, solid content is adjusted and reaches 20%~30%, add 10~
15% anaerobic fermentation inoculum carries out producing methane through anaerobic fermentation, and fermentation period is 18~20 days；
4) reactor top is the biogas that generates of anaerobic reaction there are certain space, and the biogas in reactor passes through air blower
Pressurization enters desulfurizer, and desulfurization process rear portion is used as boiler flue gas, and the high-temperature-hot-water or steam that boiler generates are made
For the heat source of anaerobic fermentation, to regulate and control fermentation temperature and time, winter can also provide heat source for heating；Another part biogas into
Enter purification system, biogas enters gas ductwork after purification；
5) biogas residue and biogas liquid obtained by step 3) is separated by solid-liquid separation, obtains the biogas residue of biogas slurry and moisture content 50~55%；
6) biogas slurry is as organic fertilizer application in crop or greenhouse crops；
7) biogas residue enters pyrolysis reactor, carries out pyrolysis and produces gas, after being warming up to 650~750 DEG C by given pace from room temperature
It is kept for 2~3 hours.
Preferably, it is added in the step 1) to account for 5~10% hydrogen peroxide of percentages and 2 of crop material dry matter
~5% urea, the agricultural urea that hydrogen peroxide is the chemically pure reagent of concentration 30%, urea is commercially available leaded wastewater 47%.
Preferably, pretreated temperature is 30~40 DEG C in the step 1).
Preferably, the pyrolysis temperature of the step 2) is 60~70 DEG C.
Preferably, the step 3) anaerobic fermentation is carried out at 50~55 DEG C of temperature, 300~500pa of pressure.
Preferably, step 3) the anaerobic fermentation pH value is 7.2~7.4.
Preferably, heating rate is 45~50 DEG C/min in the step 7).
The beneficial effects obtained by the present invention are as follows being:
1, crop material pretreatment and pyrolysis can significantly improve the degradation rate of crop material, locate in advance relative to without stalk
The direct fermentation of reason, the present invention can effectively improve the utilization rate of stalk, improve and produce biogas efficiency, shorten fermentation time；
2, degrade after crop material anaerobic fermentation is carried out in conjunction with feces of livestock and poultry, optimize raw material pretreatment time and
Structure configuration enables entire reaction process to stablize, efficiently carry out；
3, using biogas residue as pyrolysis feed, it can not only solve the problems, such as that biogas residue using hardly possible, also can produce pyrolysis gas and activity
Carbon；
4, waste material utilizationization is realized, the characteristic of crop material and excrement, fermentation time reduction are taken full advantage of
It is 10-20 days, solves the problems such as single fermenting raw materials period is long, factor of created gase is low and fermentation system is unstable；
5, the present invention be pyrolyzed and to anaerobic fermentation to stalk using the biogas slurry generated after feces of livestock and poultry anaerobic fermentation
Mixture carry out mist spray, using the features such as biogas slurry yield is big, temperature is high, methanogen population is abundant, not only realize to animal dung
Just the recycling of biogas slurry generated after fermenting, moreover it is possible to effectively shorten fermentation time.
