Abstract
The invention relates to a production method for organic fertilizers, in particular to a method for producing organic solid fertilizers by using sludge. The method for producing organic solid fertilizers by using sludge comprises the following steps of: a) sludge collection; b) pretreatment; c) drying; d) crushing; e) fermentation; f) drying; g) packaging, warehousing and the like. The method for producing organic solid fertilizers by using sludge has the advantages that harmful bacteria such as pathogenic microbes and parasitic ova can be effectively removed, only lime powder is used in the entire production method and secondary environmental pollution is not caused. Besides, after the organic solid fertilizers are used for crops such as soybeans, wheat and corns, a better yield increasing effect can be taken.
Description
Technical field
The present invention relates to the method for manufacture of fertilizer, be specifically related to a kind of method of making organic solid fertilizer with mud.
Background technology
Mud is the flow-like material that a kind of water ratio is high, become black or chocolate, generally is the aggregate that the zoogloea that formed by multiple mikrobe and adsorbed organic matter thereof and inorganics are combined into; It is mainly derived from municipal sludge, pipe network mud, river and lake silt, industrial sludge.Along with developing rapidly of urbanization; Urban sewage treatment system perfect; The quantity discharged of various mud also increases day by day, and particularly municipal sludge has become one type of maximum mud of quantity discharged, and becoming influences the key factor that can urban construction and urban sewage treatment system normally move.Mud not only water ratio high, perishable, can send the intensive stink after rotting; It has also concentrated nutritive substances such as the most of organic matter in the sewage, nitrogen, phosphorus; Heavy metal and salt and pathogeny mikrobe of discussing and parasitic ovum etc.; If directly get into environment without reasonably handling, can have a strong impact on city appearance, water body and edatope.
Nutritive substances such as the organic matter that contains in the mud, nitrogen, phosphorus; The fertilizer that can be used for plant-growth; But because it contains harmful bacterial classifications such as pathogeny mikrobe and parasitic ovum, directly discharge in the farmland or mountain forest, can produce and make bad, the mashed root of seed development, form problems such as disease.Therefore, must just can be applied through strict processing.
Though the existing method of producing organic fertilizer from sludge material of utilizing has reached the requirement of using to a certain extent; But all need use chemical reagent in these methods; Like other reagent such as acid, alkali, not only cost is higher, and if chemical reagent can not well remove also and can cause secondary pollution.
Summary of the invention
In order to overcome above-mentioned defective, the object of the present invention is to provide a kind of method with mud manufacturing organic solid fertilizer, both made full use of the effective constituent in the mud, can prevent second environmental pollution again.
For realizing above-mentioned purpose, the technical scheme that the present invention adopted is following:
A kind of with the fertile method of mud manufacturing organic solid, it may further comprise the steps
(a) collect mud: introduce in the collecting tank after wet mud is tackled oarse-grained dregs with grid;
(b) pre-treatment: add the heavy metal extraction agent in the mud after collecting, and stir, afterwards individual hour of microwave oscillation 1-5 again;
(c) drying: the mud through after the pre-treatment is sent into drying system through travelling belt, and mud is lower than 10% along with travelling belt is dried to moisture content in drying system;
(d) pulverize: mud can produce caking in drying process, dried mud is transferred in the kibbler pulverizes;
(e) fermentation: add organic matter in the dewatered sludge after pulverizing, after mixing, add living microorganism and ferment; Fermentation time is 5-10 days, during every day stir once;
(f) oven dry: dry by the fire to 7-9 one-tenth the fertilizer after the above-mentioned fermentation completion dried;
(g) packing warehouse-in: after the oven dry, above-mentioned fertilizer is packed, warehouse-in is preserved.
In said (e) step, organic add-on accounts for the 10-20% of dewatered sludge weight, and the consumption of living microorganism is at the gross weight meta 10-20g/ ton of organic and dewatered sludge.
Said heavy metal extraction agent is one or more mixing in Hydrocerol A, sulfuric acid, the nitric acid; The consumption of heavy metal extraction agent is every cubic metre of mud of 15-20g.A kind of extraction agent be difficult to simultaneously to heavy metals all in the mud extraction effect all be best; Can select for use multiple extraction combination to use for various heavy to reach best extraction effect; So this; In the preferred scheme, the heavy metal extraction agent that the present invention added is the two or more mixing of above-mentioned several kinds of extraction agents.
Wherein dry what adopt is heated drying, and the temperature of drying system is arranged on 60-80 ℃, in oven dry, can remove harmful bacterial classifications such as pathogenic bacterium in the mud, parasitic ovum.
Preferably, organic matter of the present invention is a kind of or two or more mixing in feces of livestock and poultry, wheat bran, soyabean bran, Semen Helianthi bran, dead leaf, the stalk.
Preferably, living microorganism according to the invention is one or more mixing in enzymatic microorganism, photosynthetic bacteria, actinomycetes, vinelandii and the phosphate solubilizing bacteria.
In order to guarantee the mud oven dry evenly, in the preferred scheme, drying system of the present invention is the cylinder drying unit, realizes oven dry when travelling belt rotates around cylinder.
In order to guarantee that this fertilizer can satisfy the required various effective constituents of plant-growth, in the preferred scheme, of the present inventionly make in the fertile method of organic solid when the fermentation step with mud, in the mud of doing, adds inorganic microelement before the fermentation beginning.
Described trace element is one or more mixing in sulphur, magnesium, calcium, silicon, boron, zinc, iron and the molybdenum, and the consumption of trace element accounts for the 0.1-0.5 ‰ of fertilizer gross weight.
Compare prior art, beneficial effect of the present invention is: of the present inventionly make the fertile method of organic solid with mud and can effectively remove the harmful bacterial classifications such as pathogeny mikrobe and parasitic ovum in the mud, whole production method can not cause secondary pollution to environment.Organic solid fertile no rotten odor of the present invention in addition is used for can playing production-increasing function preferably like farm crop such as soybean, wheat, corns.
Below in conjunction with embodiment the present invention is done further explain.
