Description
Technical field
The present invention relates to technical field of fertilizers, more particularly to a kind of biogas residue organic fungi-manure and preparation method thereof.
Background technology
Farming of the people to soil at present be built upon flood it is big fertilizer on the basis of, save trouble although so doing, chemical fertilizer and
The long-time service of pesticide, has had resulted in the continuous accumulation of the poisonous and harmful substance such as soil hardening, soil pesticide residues, heavy metal, has led
Crops quality decline has been caused, has threatened food security.At the same time as living standards of the people are continuously improved, problem of food and clothing elementary solution
After certainly, high yield and high quality agricultural product and hygiene and health food are as the active demand in current social and agricultural production.For this reason, nothing
The development and production of public hazards healthy food become trend of the times, correspondingly, researching and developing also gesture for the fertilizer of nuisanceless crop growth
It must go.
Conventional fertilizers are the nutrient absorption of crop for point, generally entail the use of supernutrition element, and these
The utilization rate of nutrient is then relatively low, and the main component such as nitrogen, phosphorus utilization rate is even more to be less than 30%, while the chemistry that planting season eats
Medicine has also resulted in soil pollution while pest is killed, the nutrient such as these excessive nitrogen, phosphorus and toxic organic compound, gold
Belong to ion residues in the soil, be degrading soil quality.In the processing to these pollutants, absorption method because it is easy, efficiently,
The features such as economic, renewable, non-secondary pollution and be increasingly valued by people.Gather in activated carbon, metal oxide, shell
In numerous sorbing materials such as sugar, humic acid, ferriferous oxide due to it derives from a wealth of sources, of low cost, advantages of environment protection and obtain
To wide application and more research, but exclusive use ferriferous oxide absorbed species are single, and adsorbance is small, while prepare and receive
The ferriferous oxide of rice structure, it will usually use a large amount of organic solvents, cost is higher, is unfavorable for realizing large-scale application.
Flyash is the solid waste of coal-burning power plant's discharge, and main component is silica, aluminium oxide, calcium oxide, oxidation
Iron etc., one of its important recycling approach is as construction material brickmaking at present.And in urban construction and building demolition
During can produce substantial amounts of flyash again and give up brick, these discarded object bulk depositions, not only land occupation, but also can be to environment
Have a negative impact.The features such as main component of the flyash as flyash brick, has structural porous, and specific surface area is big, can inhale
Nitrogen, phosphorus, metal ion in attached soil etc..The components such as flyash brick flyash in the block, lime, gypsum contain aluminium, calcium, iron etc.
Various active oxide, these oxides have after modified forms the potentiality for precipitating and fixing with above pollutant.Therefore, it is sharp
Had a high potential with the modified preparation for green fertilizer of rejected fly ash brick.
The content of the invention
The defects of the object of the invention is exactly to make up prior art, there is provided a kind of biogas residue organic fungi-manure and its preparation side
Method.
The present invention is achieved by the following technical solutions：
A kind of biogas residue organic fungi-manure, is prepared by the following method：
（1）By biogas residue and water in mass ratio 1：Anaerobic fermentation 3-4 weeks after 12-15 mixing, then gross mass 1-1.5% is added thereto
Polyacrylamide, stood after stirring evenly 20-24 it is small when, then charcoal is added thereto, is sufficiently stirred to obtain paste mixture,
It is spare that crushed after being dried crosses 50-80 mesh sieves；
（2）Configuration quality fraction is the syrup of 20-25%, is boiled 5-6 minutes postcoolings to room temperature, takes commercially available EM bacteria agent, press
5-10g/L is dissolved in the syrup of cooling, is stirred evenly, and it is spare to obtain bacterium solution；
（3）0.5mol/L Adlerikas and 1mol/L sodium hydroxide solutions are mixed in equal volume, stirring 10-15 minutes after again to
Wherein add magnesium sulfate powder, and heat at 110-120 DEG C 10-12 it is small when, solid precipitation is obtained after natural cooling, it is dry
Mix and immerse completely in water with iron chloride afterwards, stirred 60-90 minutes with 300-350 revs/min of speed, collect sediment,
It is eluted with water and is placed in baking oven, it is dry at 130-150 DEG C, and within levigate to 0.05 millimeter, it is standby to obtain nano-iron oxide
With；
（4）Flyash is immersed in 2mol/L sulfuric acid solutions, stirring is filtered after 20-30 minutes, then is sent in baking oven, in
When 105-110 DEG C of drying 2-3 is small, modified coal ash is obtained, by it with powdered carbon, nano-iron oxide in mass ratio（16-18）：1：
（1-3）It is immersed in after mixing in 1mol/L zinc nitrate solutions, stirring is filtered after 30-40 minutes, collects solid and at 100-105 DEG C
Lower dries pulverizing, it is spare to obtain the immobilized nano-iron oxide powder of flyash；
（5）By step 1 resulting material and step 4 gained powder in mass ratio（46-47）：（3-4）Made in mixing input comminutor
Grain, gained particle with step 2 gained bacterium solution carries out surface atomizing, and to be sprayed to particle surface completely moist and dry at 20-35 DEG C
It is dry, up to organic fungi-manure of the present invention.
The preparation method of the biogas residue organic fungi-manure, charcoal is in kind of shell charcoal, straw charcoal, charcoal in the step 1
Any one.
The preparation method of the biogas residue organic fungi-manure, magnesium sulfate, sodium hydroxide mixed liquor and magnesium sulfate in the step 3
Powder, the mass ratio of iron chloride are（24-25）：（7-10）：（1-1.5）.
The preparation method of the biogas residue organic fungi-manure, flyash uses levigate to 0.05 millimeter of preceding elder generation in the step 4,
It is sufficiently mixed after screening with water, passes through filtering drying after magnetic separator iron removal by magnetic separation.
The preparation method of the biogas residue organic fungi-manure, of the particle diameter in 2-6mm is screened in the step 5 in granulation process
Grain is used as finished particle.
It is an advantage of the invention that：
The present invention is wrapped up using biogas residue with charcoal, forms the organic components of fertilizer, can be slowed down fertilizer shunting and be lost, through biology
The degraded activity of bacterium persistently provides nutrient for a long time, recycles synthesis in water nano-iron oxide, by process modification using inorganic
Synthesis, avoids traditional high cost organic synthesis route, and ferriferous oxide is carried in the modified flyash of acid, utilizes
The modified rough surface obtained and pore space structure enhance the adsorption capacity of flyash and are conducive to aluminium, iron, calcium isoreactivity component
Dissolution, while strengthen the load stability of ferriferous oxide, the collaborative combination of the two significantly increases specific surface area, expands
To the species of pollutant in soil absorption, adsorption to organic matter, phosphorus, nitrogen and heavy metal is improved, and then improve farming
Soil quality, has significant effect particularly with long-term a large amount of soils using chemical fertilizer and pesticide, dirty eliminating pedo relict
A large amount of beneficial bacteriums and biomass energy rebuild soil stable state while dye, create the microenvironment of suitable for plant growth, the present invention
Raw material is cheap, prepares simply, has higher environmental benefit and economic benefit.
