Abstract

The invention relates to a compound soil improvement fertilizer and a preparing method thereof. The compound soil improvement fertilizer is prepared from, by weight, 8-20 parts of straw, 60-120 parts of sludge, 0-16 parts of water, 10-35 parts of animal faeces, 6-22 parts of sewage, 1-35 parts of urea, 0-16 parts of ammonium bicarbonate, 1-6 parts of superphosphate, 0-3 parts of potassium chloride and 0-3 parts of sterilization mould inhibitor. Building sludge and sewage are used as main raw materials of the compound soil improvement fertilizer, the raw materials are rich in organic matter and microelement, the sludge is converted into alkaline matter through high-temperature calcination to have the soil neutralizing effect, the sludge will generate a micropore structure after high-temperature calcinations, soil bulkiness is improved, sewage is added after the materials are cooled to 80 DEG C, while harmful bacteria are killed, fertility of the materials is improved, and therefore the compound soil improvement fertilizer is low in cost, high in environmental protection property and suitable for large-scale popularization.

Description

A kind of combined soil improving fertilizer and preparation method thereof
Technical field
The present invention relates to a kind of fertilizer, particularly relate to a kind of combined soil improving fertilizer and preparation thereof Method.
Background technology
In the last few years due to a large amount of uses of chemical fertilizer, some places ignore saving bit by bit of organic fertilizer With use, desalinated the mastery reaction of organic fertilizer, caused some places in using the most in a large number After fertilizer, cause the change of soil acidity or alkalinity, make some hardening soils, soil fertility go down, be no longer appropriate for The plantation of crops.This more can't bear with regard to barren soil to make China, and the dependence to chemical fertilizer adds Weight, forms vicious cycle, it is therefore desirable to promote the i.e. compound fertilizer of fertilizer fiting chemical fertilizer Use, compound fertilizer both can supplement soil with organic matter, improve microecological environment, again Fertilizer fertilizer efficiency can be made up the most not enough.
The raw material of compound fertilizer of the prior art passes through the inorganic fertilizers such as nitrogen, phosphorus, potassium and some are organic Fertilizer, or both compound fertilizer's compositions, the method for this chemical modifying, although can be temporary transient Improvement soil, but life-time service, can cause strong influence to environment, is also unfavorable for planting simultaneously The growth of thing, and its raw materials used feature of environmental protection is low, and cost is high, is not suitable for large-scale promotion.
Mankind's activity increasingly sharpens, and urban construction process is aggravated, and causes building mud, life dirt The pollutant emission such as water, city liquid dung difficulty, but rich abundant in these waste materials, sewage Organic substance, and in mud, trace element is abundant produces micro-cavernous structure after high-temperature calcination, can Improve the loft of soil, its low cost more, these waste materials, sewage are turned waste into wealth for ring Guarantor's cause gives a favor.
Summary of the invention
For the present situation of above-mentioned prior art, the technical problem to be solved is to provide A kind of materials recycling, environmental protection, the combined soil improving fertilizer and preparation method thereof of low cost.
The present invention solves the technical scheme that above-mentioned technical problem used: a kind of combined soil Improving fertilizer, each component is calculated as by weight: straw 8-20 part, mud 60-120 part, water 0-16 Part, animal wastes 10-35 part, sewage 6-22 part, carbamide 1-35 part, ammonium hydrogen carbonate 0-16 Part, calcium superphosphate 1-6 part, potassium chloride 0-3 part, biocide mildewcide 0-3 part.
Further, described sewage is sanitary sewage and city liquid dung, sanitary sewage and city excrement Shuifu County contains Organic substance, twice laid, and the feature of environmental protection is high.
The preparation method of a kind of combined soil improving fertilizer, comprises the following steps:
A, mixing: straw cutting and length are less than 30cm, fill stalk section with mud stirring Divide mixing so that the diameter of mud block is less than 10cm;
B, be dried: the material in step a is placed in hothouse, aeration-drying, makes Obtain material moisture and be reduced to 10-25%;
C, calcining: calcining in being placed in high temperature furnace through the material of step b, calcining heat is 500-800 DEG C, calcination time is 10-24h;
D, cooling: the material through step c is discharged vapours by exhaust system so that The temperature of material is down to 60-100 DEG C;
E, interpolation component: the material through step d is put into Hermetical stirring device, simultaneously In this Hermetical stirring device, add water, animal wastes and sewage and stir;
F, it is dried cooling: through step e material through being positioned in hothouse later and by row Wind system and self waste heat evaporation drying so that material is cooled to 20-38 DEG C, moisture Control For 10-15%;
G, secondary add component: by through step f material add carbamide, ammonium hydrogen carbonate, Calcium superphosphate, potassium chloride and biocide mildewcide are also uniformly mixed;
H, pulverizing: join in pulverizer by the material through step g, become crushing material Fineness is the powder of 40-70 mesh;
I, sub-sieve or granulation: the material through step h can be become different fineness by screening Product;Maybe the material through step h is joined in granulator and pelletize, be combined Type soil improvement is fertile.
Further, described sewage is sanitary sewage, city liquid dung, trade effluent and biogas residue natural pond Liquid.
Further, described straw is Caulis et Folium Oryzae, straw, corn straw, weeds shrub.
Further, described step e is provided with discharge duct in Hermetical stirring machine, this row Feed channel communicates with the high temperature furnace of step c, and calcining mud has good adsorptivity, it is possible to inhale Nitrogen in getter body so that the nitrogen content of this fertilizer is high.
Further, the exhaust system in described step f communicates with high temperature furnace, in f equipment The gas got rid of, reaches deodorizing effect in entering into calcining furnace.
Compared with prior art, it is an advantage of the current invention that: this combined soil improving fertilizer is to build Building mud and sewage is primary raw material, its raw material is rich in Organic substance and trace element, and mud is high Become after alkaline matter can play the effect of sweetening of the soil, and mud high-temperature calcination after temperature calcining Micro-cavernous structure can be produced, improve the loft of soil, add after material is cooled to 80 DEG C Sewage so that harmful bacteria is killed the fertility that simultaneously improve material, low cost of the present invention more Honest and clean, the feature of environmental protection is high, is suitable for large-scale promotion.
