Manufacturing method of fertilizer made from organic wastes

This invention relates to a method of manufacturing the fertilizer made from organic wastes such as food wastes, human excrements, animal excrements, slaugterhouse waste, henhouse waste, fish and shellfish wastes, vegetable wastes and agricultural wastes. Various wastes are mixed and crushed into certain sizes, processes for adjusting the water content, put into the treating tank and digested by mixing a calcined lime. The present invention utilizes a dolomite or mixture of calcined lime and dolomite to provide the first treatment material. This first treatment material is mixed with the supplement material such as charcoal, saw dust, loess, zoelite, chaff, or shell powder to give compost fertilizer. It is also mixed with agricultural products such a watermelons or melons which ferment to provide a special fertilizer for the agricultural product. The treatment material can be added to water and mixed with mugwort, medicinal herb, zeolite, loess, and then extracted to provide a liquid fertilizer. As the various organic wastes are changed to organic fertilizer, the acidified soil is improved, the environmental contamination can be prevented, and the high moisturizing and the fine porous of the soil prevent drought and fertilizer loss so as to raise fertilizing efficiency.

BACKGROUND OF THE INVENTION
 1. Field of the Invention
 This invention relates to a method of manufacturing fertilizers such as a
 compost organic fertilizer, an organic fertilizer for a special crop or a
 liquid fertilizer, wherein various organic wastes are reacted with a
 natural digestant such as a calcined lime or a dolomite to give the first
 treatment material which can be used for a fertilizer source.
 As the compost organic fertilizer manufactured according to the present
 invention includes an organic fertilizer for a special crop and a liquid
 fertilizer, it can be used for rising the farmcrops productivity by
 neutralizing the acidified soil property as to be alkalic and improving
 the soil property to the high fertility.
 Also, the organic wastes used in this invention includes all organic wastes
 which can be occurred in our life environment such a food wastes, various
 organic wastes occurred in a slaughterhouse and a henhouse, human
 excrements, animal excrements, vegetable wastes or agricultural wastes.
 The present invention manufactures an organic fertilizer like a barnyard
 manure by following methods: The organic wastes is gathered to be
 processed for a treatment and then putted into a treating tank, wherein
 natural digestants such as a calcine lime or a dolomite are used for
 digestion in single or in combination to remove the toxicity of organic
 wastes, and to sterilize and deodorize the organic wastes which is changed
 into a fertilizer source;
 To the first treatment material for a fertilizer source, a loess, a
 zeolite, a saw dust, a chaff, a grass cutting material and like are added
 and mixed to be fermented; agricultural products such a watermelon, a
 melon, a cucumber or a tomato which are to be abandoned because is has no
 value as commodities are gathered, finely cut, mixed with the fertilizer
 source and fermented; Chinese crude drugs such as a mugwort or a medicinal
 herb are mixed to the fertilizer source with a supplement material and a
 raw water is added thereto, the mixed material is ripened for a
 considerable period and then it is squeezed to make a liquid fertilizer;
 or the treating material remained after manufacturing the fertilizer as
 the above process is fermented by adding the supplement material such as a
 charcoal, saw dust, shell powder to give an organic fertilizer like a
 barnyard manure.
 As known, a calcined lime is the usual name of calcium oxide and it is
 obtained by burning limestone or hydroxide but if it contacts with water
 it is to be calcium hydroxide with high heat, that is, it has a natural
 digestive function (a calcined lime is changed by adding water to calcium
 hydroxide), therefore, if organic wastes are treated by utilizing the
 function, the organic wastes are hydrolyzed to be digested in a treating
 tank so that without a separate drug the toxicity thereof is neutralized,
 it is sterilized and is deodorized.
 As the dolomite is a carbonate mineral which is called as a baekoonsuk or
 kohoysuk, it is the double salt of CaCO.sub.3 and MgCO.sub.3 and is
 presented as common fabrication, granular and granule compact. Beside,
 since it has a high magnesium content and is alkalic, if it is mixed and
 reacted with organic wastes which have high moisture, it shows the
 digestive function with high heat to neutralize the toxicity of organic
 wastes and sterilize the organic wastes with removing the odor, therefore,
 it digests organic wastes to be a fertilizer source.
 The present invention is characterized in that by using the above methods
 organic wastes is changed to be a fertilizer.
 2. Description of the Prior Art
 In our life environment, preposterous organic wastes related to our life
 are occurred but it is organic substance so that it is easy to be
 decomposed. Therefore, the bad smell and the toxin generated during the
 decomposition give a damage to our life.
 However, for treating that, a considerable expense has been spent but the
 effective treating method has been not developed, besides, because of many
 wastes abandonment or discharge, the life environment has been
 contaminated to cause diseases.
 Simultaneously, the oxidation in our land is promoted due to the abuse of
 chemical fertilizer so that the fertility of soil is diminished to fall
 down the productivity thereof.
 SUMMARY OF THE INVENTION
 This invention is designed to solve the problems faced to the realities of
 life, the object of the invention is to provide a method of manufacturing
 organic fertilizers suited for purpose, wherein preposterous organic
 wastes are reacted with a natural digestant, i.e., a mineral material such
 as a calcined lime or a dolomite to neutralize the toxicity and remove the
 odor with sterilizing therein so as to give the fertilizer source, and
 then, the special supplement material is added thereto for the secondary
 processing.

DETAIL DESCRIPTION OF THE INVENTION
 The present invention provides the fertilizer source which can be used in
 manufacturing fertilizers: wherein various organic wastes described in
 above are gathered according to the type thereof, crushed or mixed to be
 processed into good state for treating and to have moisture in
 60.about.80% thereof, and then the mixture is put into the treating tank 1
 and reacted by a natural digestant, that is, the organic wastes contacts
 with the digestant to be digested simultaneously with being hydrolyzed in
 the treating tank, therefore, the toxicity of the organic wastes is
 neutralized; the organic wastes are sterilized; and the odor of the
 organic wastes is removed, that is, the first treatment is accomplished to
 provide the fertilizer source which can be used in manufacturing the
 fertilizers.
 At this time, as the natural digestant used for a digesting, a calcined
 lime or a dolomite is used
 For that, the present invention uses the treating tank 1 in which a pair of
 screw type stirring conveyor 1a is installed to complete the treatment in
 1.about.2 hours. The amount of the digestant used at that time is
 preferably 30.about.50 weight %.
 The first treatment material digested as above is taken by the following
 treatment according to the purpose of the fertilizer to provide the
 organic fertilizer.
 1) The first treatment material is put into the second treating tank 2 and
 mixed with zeolite 5%, loess 5%, saw dust 10%, chaff 10%, grass powder 20%
 and stirred for 20.about.40 minutes, and then it is extracted to be
 fermented artificially in a fermentation chamber for 10.about.15 days to
 provide the compost fertilizer.
 2)The first treatment material is put into the second treating tank 2, the
 cutting material of agriculture products is added 20 weight % to the whole
 amount and stirred for 20.about.40 minutes and extracted to be fermented
 artificially in a fermentation for 5.about.15 days to give the special
 organic fertilizer for a watermelon, a melon, a cucumber, a carrot, a
 tomato and a pepper, the agriculture products being a watermelon, a melon,
 a cucumber, a carrot, a tomato, a pepper and like which are abandoned due
 to the valuelessness as a commodity.
 3) The first treatment material is put into the second treating tank 2, the
 raw water is poured thereto, charcoal 5%, mugwort 5%, medicinal herb
 crushing material 20%, zeolite 5% and loess 5% are mixed therewith and
 stirred for 20.about.40 minutes, and then the mixture if ripened in the
 storage tank 4 for 2.about.3 days, and then the ripened material is
 extracted and the juice thereof is precipitated to give a liquid
 fertilizer, the remained treatment is mixed with the additive 10 weight %
 such as shell powder to be fermented artificially about 10 days to provide
 the compost organic fertilizer.
 The fertilizer of the present invention manufactured according to the above
 methods has merits: since the organic wastes are reacted with the organic
 digestant, i.e., a calcine lime or a dolomite to be digested, without
 drugs, the toxicity and the odor of the organic material are removed and
 also the sterilization source is accomplished to provide the fertilizer
 source so that the safe fertilizer source can be manufactured at low
 expenses; and in such fertilizer source, the salt is removed, various
 heavy metal and hazard bacteria are destructed, and organic substance is
 rich, therefore it can become the fertilizer which can plant consequently
 because it has high effectiveness in manufacturing the barnyard manure,
 the special fertilizer for a protected agriculture, the liquid fertilizer,
 the organic fertilizer. As using the fertilizer, the acidic soil can be
 improved and the good crops can be produced, whereby the environment
 attractive organic agriculture can be nurtured.
 Therefore, as the present invention has been developed, all organic wastes
 are quickly treated in large quantities without any chemicals to be the
 organic fertilizer so that the high value-added wastes treatment become
 possible to maximize the economic efficiency and the profitability. Also,
 the environment deterioration during the treating process can be prevented
 and the waste water is not occurred, therefore, the invention is
 environment-attractive, and it can minimize the treating expense and
 develop the related industries.
 Particularly, the zeolite is microporous (2000m.sup.2 /g) and has the water
 and the fertilizer component which is slowly discharged, that is, it has
 the moisturizing and the fertilizing function so that the drought damage
 and the fertilizer loss can be prevented. Besides, since it has the
 special effect such as the progress of the air permeability, it can give
 the substantial help.
