The preparation method comprises the following steps: (1) preparing water soluble organic carbon slurry: oxidizing organic wastes by H2O2, and carrying out suction filtration to remove impurities to obtain water soluble organic carbon slurry; (2) preparing urea phosphate slurry: degrading phosphorous ores by sulfuric acid or nitric acid to obtain wet-process phosphoric acid, adding urea, and carrying out suction filtration to remove impurities to obtain urea phosphate slurry; (3) carrying out neutralization and granulation. The preparation method has the advantages that a protective oxidation method is adopted to reduce discharge of carbon dioxide, the utilization rate of carbon resources is increased; the produced macro element water soluble fertilizer can supply enough nutrients for the growth of crops, is capable of improving the soil, and solves the problem of single nutrient of chemical fertilizers; the using amount of fertilizer is reduced by 20 to 30%, compared with the using amount of common fertilizer; and the nutrient utilization rate in trickle irrigation can reach 60 to 85%. The fertilizer is prepared by a unique technology, comprises urea phosphate, and can reduce or prevent the phenomenon of scaling and obstruction of a trickle irrigation system, and thus the service life of the trickle irrigation system is prolonged.
Description
Technical field
The invention belongs to technical field of agricultural fertilizers, being specifically related to one and utilize food processing yeast waste liquor, monosodium glutamate waste liquid, the waste liquid such as domestic sewage factory biological activated sludge, bio-pharmaceuticals factory biofermentation dreg, plant's fowl and animal excrement makes containing water-soluble Organic carbon a great number of elements Water soluble fertilizer and preparation method thereof.
Background technology
China's chemical fertilizer this season utilization rate nitrogenous fertilizer 20～35%, phosphate fertilizer 10～25%, potash fertilizer 35～50%.Fertilizer poor efficiency, not only causes the wasting of resources, also results in the problem of environmental pollutions such as Soil structure deterioration, water eutrophication and nitrogen oxide discharging.Solving a major measure of these problems is development high-efficiency water-saving industrialized agriculture, Water soluble fertilizer convenient can spray as novel environment friendly Fertilizer application, rush execute and can and spray drop fill and be utilized in conjunction with improving utilization rate of fertilizer, save agricultural water, reduce ecological environmental pollution, improve crop quality and reduce the aspect clear superiorities such as labour force.But China's Water soluble fertilizer is the single chemical fertilizer of N P and K a great number of elements or medium trace element mostly at present, the single chemical fertilizer of chronic administration easily causes soil agllutination, Fertility Degeneration, crop quality decline.Meanwhile, domestic water-soluble fertilizer product is by selecting highly-water-soluble raw material mostly, or adopts physical method that raw material is levigate, and to improve product water dissolubility, such method all exists high cost, fails to solve very well shower nozzle blockage problem.In the north, water, Ca, Mg and Fe content is high, and it forms insoluble phosphate with the water solublity phosphorus source (such as ammonium hydrogen phosphate, potassium phosphate etc.) in fertilizer, blocks shower nozzle, reduces facility service efficiency.
Water Soluble Organic Carbon (water-solubleorganiccarbon, abbreviation WSOC) typically refer to the Water-soluble Organic Substances that can pass through 0.45 μm of microporous filter membrane, although WSOC only accounts for little part of soil organic matter, general content is less than 200mg/kg, but it is the organic carbon source that soil microorganism can directly utilize, and it also can affect organic in soil and the conversion of inorganic substances, migration and degraded, as affected the migration in soil of heavy metal and pesticide and soil to P and SO4 2-Absorption etc. Deng inorganic ions.
Humic acids has higher cation converted quantity, higher more than 10 times than general soil.After being manured into soil, make soil that Anion-adsorption ability to be significantly improved, make capping salt content reduce.Changing that saliferous in soil is too high, the physicochemical character of grogs high degree of dispersion, Soil structure difference, promoting the formation of soil agreegate so that it is become kilter, thus growing, for plant root growth, the condition that creation is good.Humic acids can promote the activity of soil microorganism, increases the facts such as the quantity of soil microorganism, the activity of enhancing soil enzyme, is confirmed by a large amount of research datas both at home and abroad.And unanimously think, use humic acids make aerophile bacterium, actinomycetes, cellulose-decomposing bacteria quantity increase more.To accelerating organic mineralising, promote that the release of nutrient is favourable.Therefore, humic acids can prevent and treat the root rot of fruit tree, Huang Ye, lobule, droop.
H2O2It is widely used in Organic substance as a kind of green strong oxidizer to process, water and oxygen can be resolved into because of it in the ordinary course of things, do not result in secondary environmental pollution.But when processing organic waste, particularly in food processing waste processing procedure, owing to being mostly acid treatment waste liquid, and mostly containing a certain amount of Fe in Organic substance, easily there is Fenton reaction, ultimately generate CO2, and H2O, along with global climate become dim trend increase the weight of, and to generation CO2Emission problem is increasingly paid attention to, and meanwhile, is also a kind of waste to charcoal resource.Fenton oxidation method is to invent first for 1894, H2O2At Fe2+Having the ability of oxidation gas chromatography under the catalytic action of ion, Fenton reagent has extremely strong oxidability, be particularly well-suited to multiple difficult for biological degradation or in process to biological virose industrial wastewater.But because Fe existence form in the solution is limited by the pH value of solution, so Fenton reagent is only had an effect in acid condition, neutral with in alkaline environment, Fe can not catalysis H2O2Produce OH.Researcher is it is believed that when pH value is in 2～4 scopes, oxidized waste water treatment effect is better, when optimum efficiency occurs in pH=3.Lin and Peng finds when adopting Fenton reagent to process textile waste, and when pH value increases over 3, the COD in waste water raises rapidly, thus obtaining optimum point pH=3.Under this condition, the clearance of COD reaches 80%.
Such as China Patent Publication No. CN103435389A, disclose a kind of method utilizing microbial cell waste liquid to prepare bacterium peptide fertilizer, this patent is by solid-liquid separation after microbial cell waste liquid employing quick lime or concentrated sulphuric acid hydrolysis, the method produces a large amount of waste water, and course of reaction produces all to cause secondary environmental pollution containing a large amount of water-soluble minerals and organic matter in waste gas and waste water.Such as China Patent Publication No. CN103524175A, disclose a kind of containing alginic acid organic water-soluble fertilizer and production method thereof, this patent adopts the method for supersonic wave wall breaking chopping that seaweeds organic material is carried out pretreatment, and utilize papain enzymolysis profit alginic acid, but due to alginic acid in water, methanol, ethanol, acetone, chloroform insoluble, only dissolve in sodium hydroxide aqueous slkali, and it easily generates precipitate with bivalence Ca, Mg and Fe, therefore such Water soluble fertilizer easily causes droping irrigating pipe, shower nozzle fouling, affects facility operation efficiency..
