Description
Technical field
The present invention relates to a kind of fertilizer and production method thereof, particularly utilize sludge generated in municipal domestic sewage to make organic fertilizer and preparation method thereof.
Background technology
In order to protect environment, all be provided with sanitary sewage disposal factory in the city now.City resident's sanitary sewage enters sanitary sewage disposal factory by pipeline, through processes such as oxygenation, stirring, fermentation, precipitations, sewage is become clean, free of contamination water, has protected river course and urban water resource, has protected environment.But at this simultaneously, can produce a large amount of mud in the process of processing city domestic sewage.The organic substance that contains in the sanitary sewage becomes sludge settling after treatment and gets off, and every day, big and small various sanitary sewage disposal factory all can produce a large amount of mud.Here it is sanitary sewage disposal mud claims biological sludge again.In the sanitary sewage disposal mud, contain the moisture content of 70-80%, contain organic matter and n-p-k element.Since city domestic sewage treatment plant set up, people were making great efforts to study the fertilizer that how to utilize sanitary sewage disposal mud, particularly people to expect to make with sanitary sewage disposal mud the agriculture production use always, but produce little effect.Environmental administration, agricultural sector drop into a large amount of funds and manpower for a long time, all can't address this problem.Its basic reason is: the moisture in the sanitary sewage disposal mud is colloid water, is not free state water.The colloid water that moisture in traditional object is handled in the mud with the way of processing free state water such as extracting, press dry, dry, dry, wind is done does not all have effect.The for example domestic unit that has handles mud with the method for hyperthermia drying, and moisture is dried as a result, and the organic matter in the mud is become the simple substance carbon element by high-temp combustion, becomes inorganic states from organic, has lost the function as fertilizer.Because prior art can't be utilized sanitary sewage disposal mud, mud is stacked in the sewage work for a long time, forms secondary pollution.This problem long-term existence can't solve, and mud is piled up more and more, becomes a big problem that presses for solution.Owing to contain organic matter and n-p-k element in the sanitary sewage disposal mud, be good agriculture production fertilizer.Therefore inventing a kind of is very necessary with the mud manufacturing organic fertilizer residual after the city domestic sewage processing and the preparation method of this organic fertilizer.
The present invention's acid treatment mud mixes mutually with other raw material then, makes organic fertilizer.Through extensively consulting domestic and international public publication, retrieving domestic and international patent documentation, there is no the technical scheme identical with the present invention.
Summary of the invention
The purpose of this invention is to provide a kind of organic fertilizer that utilizes sanitary sewage disposal mud for raw material;
Another object of the present invention provides a kind of preparation method of organic fertilizer produced from sludge generated in sewage treatment.
The object of the present invention is achieved like this:
A kind of organic fertilizer produced from sludge generated in sewage treatment, form by the material of following ratio of weight and number:
100 parts of organism, nitrogen phosphorus potassium raw materials;
Sanitary sewage disposal mud 8-15 part;
98% vitriol oil 2.5-3.5 part;
Liquefied ammonia 1.5-2.5 part;
Organic fertilizer produced from sludge generated in sewage treatment, best composition is:
100 parts of organism, nitrogen phosphorus potassium raw materials;
10 parts in sanitary sewage disposal mud;
3 parts of 98% vitriol oils;
2 parts in liquefied ammonia;
Organism, nitrogen phosphorus potassium raw material are meant the conventional raw material of producing organic substance raw material that organic and inorganic mixed fertilizer uses and nitrogenous, phosphorus, potassium;
Sanitary sewage disposal mud is meant residual mud behind the sanitary sewage disposal factory and office reasons sanitary sewage;
Liquefied ammonia is meant liquid ammonia.
The preparation method of organic fertilizer produced from sludge generated in sewage treatment may further comprise the steps:
(1) sanitary sewage disposal mud is put into container, add 98% vitriol oil, stir;
(2) organism, nitrogen phosphorus potassium raw material are put into stirrer, the mixture of above-mentioned steps (1) is put into stirrer;
(3) material after step (2) stirring is sent in the tablets press by feed belt;
(4) in tablets press, add liquefied ammonia, granulation;
(5) material after the granulation is sent into dryer, sifting machine successively;
(6) material after will screening is weighed, packs, is put in storage.
Main points of the present invention are the colloid water that utilizes in 98% vitriol oil absorption sanitary sewage disposal mud, and the vitriol oil is diluted, and the moisture content in the mud reduces, and mixes with the raw material of producing fertilizer then, produces the fertilizer of various different N-P-K contents and organic content.
The sanitary sewage disposal mud of indication of the present invention is meant residual mud behind the sanitary sewage disposal factory and office reasons sanitary sewage, and the free state water in these mud is discharged from, only contains the colloid moisture that ordinary method can't be discharged.
The organism of indication of the present invention comprises plant roots and stems, tangerine bar, blade, shell, through heap fermentation, or the material of fermentation tower fermentation after drying; Comprise without fermentation, directly be dried, material such as comminuted plants tangerine bar, rhizome, blade, shell; Also comprise animal dung such as chicken, duck, dove, pig, ox, sheep; All can be used as the organic substance of fertilizer material to comprise monosodium glutamate waste residue, brew wine waste residue, citric acid waste residue and other.
The nitrogen phosphorus potassium raw material of indication of the present invention comprises urea, ammonium sulfate, monoammonium phosphate, diammonium phosphate, calcium superphosphate, fused(calcium magnesium)phosphate, Repone K, vitriolate of tartar, and other all can be used as the fertilizer that contains nitrogen phosphorus potassium of composite fertilizer raw material.
98% vitriol oil of indication of the present invention is meant the anhydrous slufuric acid that people say usually.
Preparation method of the present invention puts into container except step (1) with sanitary sewage disposal mud, adds 98% vitriol oil, outside the stirring; Other step is identical with equipment with the existing composite fertilizer preparation process of producing with equipment.
The present invention utilizes the vitriol oil to handle the residual mud of sanitary sewage disposal factory in the world first, uses it as raw material then, produces organic fertilizer, has significant novelty and creativeness.Because the mud raw material that the present invention uses is extensive, fertilizer product of the present invention is widely used, so the present invention has practicality widely.The present invention simultaneously is an invention that solves the sanitary sewage disposal factory mud secondary pollution difficult problem that people thirst for solving for a long time.
Advantage of the present invention is:
