Description
Technical field
The present invention relates to manure fermentation, particularly a kind of method being prepared fertilizer by mixing animal excrement.
Background technology
Along with China's expanding economy, the development of advancing by leaps and bounds that the livestock industry of China obtains.But along with the development of livestock industry, the ight soil of animal excretion brings serious problem, and it not only causes the stench of air, spreads disease, and serious environment pollution.Solve the problem of animal excrement, what mainly take is that manure fermentation is used as agricultural fertilizer, or is used as biofuel; Fermentation process mainly zymophyte conventional at present, adopts the fermentation of anaerobic and aerobic, but usually can cause bacterial contamination and ferment not thorough.
Summary of the invention
For current animal excrement fermentation Problems existing, the present invention has designed and developed a kind of method being prepared fertilizer by mixing animal excrement.
Technical scheme provided by the invention is:
Prepared a method for fertilizer by mixing animal excrement, comprising:
1 part of animal mixing ight soil, 0.5 part of calcium oxide and 15 parts of water are placed in pond, stir 20 minutes by step 1, according to the mass fraction, with concentration be 1mol/L citric acid adjust ph 6 ~ 7, add 0.5 part of EM bacterium, stir 3 ~ 4 minutes, static 10h, obtains mixture; Carry out step 2, (calcium oxide is used for the preliminary deodorizing of animal excrement, uses citric acid the pH value of ight soil to be adjusted to the scope being applicable to the effect of EM bacterium, citric acid is a kind of organic acid, nontoxicity, can not introduce other ions, safe green, EM bacterium is used to be used for carrying out secondary deodorizing to animal excrement, reach the effect of thorough deodorizing, simultaneously by calcium oxide and EM bacterium used in combination, not only can reach the effect of the deodorizing to ight soil, and economical, decrease the usage quantity of EM bacterium.)
Step 2, with sodium hydroxide, the pH value of the mixture prepared in step 1 is adjusted to 8, adds 0.0005 part of neutral protease, 55 DEG C are heated to mixture, enzymolysis 3h; Carry out step 3, (use proteolytic enzyme to carry out enzymolysis to the protein in animal excrement, become short chain polypeptides and micromolecular amino acid, be conducive to plant absorption)
Step 3, the mixture after being processed by step 2 is placed in steaming and decocting under high pressure pot, be 1.5 normal atmosphere at pressure, temperature is at 120 DEG C, boiling 20 ~ 30min, cooling mixture to 30 DEG C; Carry out step 4, (object one of steaming and decocting under high pressure to eliminate some virus, bacterium, worm's ovum and parasite in ight soil, prevents following process from causing instrumental pollution, the Health hazard caused staff and in use to the disease etc. that farm crop are caused; Two is for proteolytic enzyme deactivation, prevents proteolytic enzyme by undue for protein enzymolysis; High temperature steaming plays the effect of the preliminary pulverizing to ight soil simultaneously)
Step 4, by the mixture pulverization process after processing through step 3 four times, wherein each pulverization process comprises and stirs 1h, water bath sonicator 40min, and bath temperature is 38 DEG C; Carry out step 5, (pulverize ight soil, be not only conducive to the fermentation of subsequent fermentation bacterium, improve fermentation rate, and be conducive to the absorption of plant; Ultrasonicly effectively can pulverize ight soil, make macromolecular nutritive substance further simultaneously, be transformed into the nutritive substance that small molecules is easy to absorb.)
Step 5,5 portions of marine algas are placed in closed box body, the sidewall of box body offers multiple through hole, and the aperture of each through hole is 6mm, box body is placed in the mixture after step 4 processes, and stirs the mixture 15 minutes, takes out described box body; Carry out step 6, (marine alga has the ability of stronger Adsorption of Heavy Metals, utilizes the heavy metal in marine alage adsorption ight soil here, prevents it to farm crop and soil pollution, is contained in closed zoarium by marine alga, be conducive to the taking-up of marine alga.)
Step 6, the mixture after processing through step 5 is placed in fermentor tank, be that the pH value of mixture is adjusted to 5 by the hydrochloric acid soln of 0.002mol/L by concentration, in fermentation unit, add 0.002 part of milk-acid bacteria, be 30 DEG C of conditions at 1 normal atmosphere and temperature, anaerobic fermentation 5 days;
In mixture, add 0.02 portion of yucca, 0.06 portion of Grosvenor Momordica, 0.03 portion of oyster shells, 0.0006 part of EM bacterium and 0.003 portion of straw feed starter, be 35 DEG C of conditions at 1 normal atmosphere and temperature, anaerobic fermentation 2 days;
In mixture, add 0.03 part of manure fermentation agent, be 45 DEG C of conditions at 1 normal atmosphere and temperature, anaerobic fermentation 7 days, collects biogas, be cooled to 20 ~ 25 DEG C; Carry out step 7, (the present invention adopts the method for gradient fermentation stage by stage, first utilizes milk-acid bacteria to ight soil initial fermentation, tentatively to manure fermentation; Then adopt EM bacterium and 0.003 portion of straw feed starter to animal excrement and the yucca added, Grosvenor Momordica and oyster shells, so not only prevent excessive fermentation, destroy some nutritive ingredients in yucca, Grosvenor Momordica and oyster shells, reduce the generation of peculiar smell simultaneously, finally use manure fermentation agent to complete the last fermentation of ight soil.)
Step 7, step 6 is processed after mixture join in steaming and decocting under high pressure pot, at 90 DEG C, 1.2 normal atmosphere, steaming and decocting under high pressure 5 minutes, pressure release to one normal atmosphere, cooling mixture to 15 DEG C, adds 0.005 part of nano-sized carbon to mixture, stir 10 minutes, namely obtain fertilizer.(final sterilization, eliminate fermenting process become in produce unwanted bacteria, fungi etc., nano-sized carbon add the absorption that farm crop can be promoted fertilizer.)
Preferably, prepare in the method for fertilizer by mixing animal excrement, in described step 1, every part of animal mixing ight soil comprise mass ratio be 1: 10: 0.5: 2: 1 chicken manure, cow dung, rabbit excrement, pig manure and sheep excrement.(solve cow dung not tractable effect, and to be fermented the fertilizer by such proportioning, fertilizer is strong)
Preferably, prepare in the method for fertilizer by mixing animal excrement, in described step 6, yucca length is 6mm.(being conducive to fermentation and farm crop absorption)
Preferably, described prepares in the method for fertilizer by mixing animal excrement, in described step 6, oyster shells is ground to form the powder that particle diameter is 30 μm, joins in mixture.
