A kind of method utilizing mud to prepare fertilizer
Technical field
The present invention relates to a kind of method preparing fertilizer, particularly to a kind of method utilizing mud to prepare fertilizer.
Background technology
Mud is in hydrostatic or deposition in flowing water environment slowly, through physical chemistry and what biological chemistry action was formed, unconsolidated weak particulate or superfine particle soil, belongs to modern recent deposit thing.Producing substantial amounts of mud after a lot of sanitary sewage disposals now, a few major part of these mud is all fall as garbage disposal.But processing these mud, one is that process is pretty troublesome, because amount of sludge is big, the substance classes that the inside comprises is more, so mud component is comparatively dangerous;Two are, because volume is big, component uneasy congruence factor causes expending substantial amounts of fund when processing.China's field-crop for a long time imposes chemical fertilizer so that soil becomes barren, plate, thus causing that soil is increasingly not suitable for cultivating.
Therefore, for mud produced in sanitary sewage disposal be difficult to process the process taking measures to optimize mud and more and more barrenr to take corresponding physical measure to improve soil property for soil, the problem such as increase soil fertility extremely urgent.
Summary of the invention
The present invention is directed to above-mentioned technical problem, invent a kind of method utilizing mud to prepare fertilizer, the present invention utilizes the mud produced after sewage disposal in life as raw material, prepare the organic fertilizer that a kind of fertilizer efficiency is good, the method had both solved the problem that sludge treatment is difficult, also turn waste into wealth, improve the utilization rate of mud.
For solving above-mentioned technical problem, technical scheme is as follows:
A kind of method utilizing mud to prepare fertilizer, comprises following operating procedure:
(1) being taken out by mud, be exposed to the sun 12~36h under the sun, crosses screen cloth, and after sieving, gained mud is standby;
(2) by 2.5~5.0kg heap, gained mud after sieving in step (1) being made a pile, often heap is put into the pulverized limestone of 0.25~0.5kg and is mixed homogeneously with mud;
(3) being covered by the mud heap mixed with pulverized limestone in step (2) with the crop material of 5.0~10.0kg, then light crop material, mud is mixed homogeneously by the crop material afterburnt with crop material ashes, namely obtains fertilizer after placing 6~9d.
Wherein, the screen cloth that screen cloth is 1~4 order described in step (1).
Wherein, the crop material described in step (3) is the one in dry corn straw, rice straw, peanut straw.
Wherein, described mud is the mud produced after sanitary sewage disposal.
Wherein, the pulverized limestone described in step (3) is calcium lime powder.
Beneficial effects of the present invention:
The present invention utilizes the mud produced in sanitary sewage disposal to prepare fertilizer, both the problem that the sludge treatment produced in the sanitary sewage solved is difficult, mud can be turned waste into wealth again, improve the utilization rate of mud, it is fertilizer that the further present invention prepares gained fertilizer, soil soil property is played good improvement result, increases soil fertility;Preparation method of the present invention is simple, technological process is easily operated, and cost is low, easily realizes.
Detailed description of the invention
Further describing the present invention referring to detailed description of the invention, to make those skilled in the art can implement according to this with reference to description word, scope is not limited to embodiments of the present invention.
Embodiment 1
The mud produced in sanitary sewage is taken out, be exposed to the sun 12h under the sun, cross the screen cloth of 1 order, after sieving, gained mud is often to pile 2.5kg as a pile, often pile the pulverized limestone putting into 0.25kg to mix homogeneously with mud, then with the dry corn straw of 5.0kg, mud heap is covered, light corn straw, treat that ashes are mixed homogeneously with mud by the corn straw afterburnt, place 6d and namely obtain organic fertilizer.
Embodiment 2
The mud produced in sanitary sewage is taken out, be exposed to the sun 24h under the sun, cross the screen cloth of 2 orders, after sieving, gained mud is often to pile 3.5kg as a pile, often pile the calcium lime powder putting into 0.35kg to mix homogeneously with mud, then with the dry rice straw of 13.0kg, mud heap is covered, light rice straw, treat that ashes are mixed homogeneously with mud by the rice straw afterburnt, place 8d and namely obtain organic fertilizer.
Embodiment 3
The mud produced in sanitary sewage is taken out, be exposed to the sun 36h under the sun, cross the screen cloth of 4 orders, after sieving, gained mud is often to pile 5.0kg as a pile, often pile the calcium lime powder putting into 0.5kg to mix homogeneously with mud, then with the drying peanut straw of 10.0kg, mud heap is covered, light peanut straw, treat that ashes are mixed homogeneously with mud by the peanut straw afterburnt, place 9d and namely obtain organic fertilizer.
The present invention utilizes the mud produced in sanitary sewage disposal to prepare fertilizer, both the problem that the sludge treatment produced in the sanitary sewage solved is difficult, mud can be turned waste into wealth again, improve the utilization rate of mud, it is fertilizer that the further present invention prepares gained fertilizer, soil soil property is played good improvement result, increases soil fertility;Preparation method of the present invention is simple, technological process is easily operated, and cost is low, easily realizes.
