Description
Technical field
The present invention relates to crop fertilizer preparation field, and in particular to a kind of side that organic fertilizer is prepared by sludge fermentation biogas residue
Method.
Background technology
With the sustainable development of the ecological agriculture, the enthusiasm more and more higher of people's development biogas ecology agricultural, the use of biogas residue
Way is also gradually exploited.Biogas residue is the semi-solid material that methane-generating pit bottom is remained in after biogas fermentation, is had containing abundant
Machine matter, humic acid, crude protein, nitrogen, phosphorus, potassium and various trace elements and auximone.
Biogas residue is due to rich in organic matter etc., therefore biogas residue aerobic compost production organic fertilizer turns into one kind that biogas residue is handled gradually
Main trend.When utilization biogas residue produces organic fertilizer, due to the difference for the original material that ferments, if any utilization livestock manure fermented shape
Into biogas residue, have using fermentation of plant straws formation biogas residue, have using sludge formation biogas residue, different fermentations material formation
Biogas residue has very big difference in terms of quality, composition, needs to be respectively processed when organic fertilizer is made, while prior art
When preparing organic fertilizer using biogas residue on the one hand it cannot be guaranteed that the equilibrium of the nutrient of obtained fertilizer, was on the other hand prepared
Nutrient in journey in biogas residue is easily lost in, and two aspect reasons cause that obtained organic fertilizer fertilizer efficiency is poor, and application effect is not obvious.
The content of the invention
In order to alleviate shortcomings and deficiencies of the prior art, sludge fermentation biogas residue is passed through it is an object of the invention to provide one kind
The method for preparing organic fertilizer, preparation method of the present invention is simple, and obtained organic fertilizer nutrition is balanced, fertilizer efficiency is high.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of method that organic fertilizer is prepared by sludge fermentation biogas residue, comprises the following steps：
(1) sludge biogas residue is taken out to progress dewater treatment from fermentation vat, control moisture content is in 30-40%；
(2) biogas residue after dewater treatment and adsorbent mixing natural air drying and pulverization process is carried out；
(3) biogas residue after pulverization process and leavening are mixed and stirred for uniform compound；
(4) mixing stockpile is subjected to aerobic fermentation in fermenting cellar；
(5) additive is added after aerobic fermentation into compound and is stirred；
(6) regulation water content is granulated, and obtains the organic fertilizer.
The sludge is slag sludge, sucrose sludge, pond sludge, sewage plant sludge.
Adsorbent is the mixture of flyash and activated carbon granule in the step (2).
Leavening is made up of aspergillus oryzae, aspergillus terricola, aspergillus niger in the step (3).
Windrow is no less than 2 cubes, 0.5 meter of feed height -0.8 meter, environment during aerobic fermentation in the step (4)
When below 18 DEG C of temperature, covered, when internal temperature is raised to 30 DEG C, covering is opened, heap temperature rise to 40 with film or straw screen or mat
DEG C when begin to tip over, then turned over once every 2-3 days.
One is set to enclose cage ring on windrow surrounding ground during aerobic fermentation in the step (4), the cage ring is by chlorine
Change calcium, sodium hypochlorite powder constituent.The close of fly worm during the fermentation is prevented by the cage ring.
Aerobic fermentation takes disinfectant measure in the step (4) after terminating, and the disinfectant measure can be used to fermenting cellar
Spray disinfectant, or disinfection by ultraviolet light light irradiation is used, by taking disinfectant measure to prevent bacterium in fermentation process, viral production
It is raw, it is ensured that the organic matter in biogas residue is not decomposed consumption.
Additive is made up of potassium dihydrogen phosphate, kaolin and sepiolite in the step (5).
Beneficial effects of the present invention are：Mix, on the one hand can be adsorbed in sludge with adsorbent after sludge is dehydrated
Peculiar smell, simultaneously because sludge quality closely forms loose porous structure using adsorbent in sludge, increase and fermentation
The contact area of agent, improves fermenting speed, shortens fermentation period, the fertile cost of reduction system；Cage ring is set in fermenting cellar, fermented
After take disinfectant measure, can farthest retain the compositions such as organic matter, humic acid, crude protein, nitrogen, phosphorus, potassium in biogas residue, keep away
Exempt to be polluted during the fermentation, while extending the storage life of organic fertilizer；By analyzing sludge fermentation biogas residue composition,
Add additive and cause obtained organic fertilizer effect more fully, be applicable to multiple kinds of crops, such as vegetable melon and fruit or grain
Crop.
