Description

A kind of high activity little molecule richness carbon is fertile and preparation method thereof
Technical field
The invention belongs to organic solid waste process and the technical field of organic fertilizer production, be that a kind of high activity little molecule richness carbon is fertile And preparation method thereof, it is specifically related to a kind of method utilizing organic waste to produce little molecule richness carbon fertilizer, particularly to a kind of base In subcritical hydrolysis method, organic waste is utilized to produce the fertile technology of high activity little molecule richness carbon and production method.
Background technology
Organic waste includes that plant garbage (such as agricultural crop straw, branch etc.), animal class garbage are (such as manure of livestock and poultry Just), processing class garbage and life kind garbage are (such as the kitchen such as dining table, food market excess, foodstuff processing factory leftover bits and pieces, life dirt Mud etc.).Organic waste has the features of pollution that quantity is big, kind is many, harm is many, and the annual organic waste number produced is with hundred million Meter, simultaneous contamination accident is also increasing year by year.These organic wastes should return with carbon or Organic substance form Go back to farmland to complete the circulation of whole material, but due in garbage beneficiating ingredient content low, available article position is the highest, and is harmful to Component content is high, such as contains the poisonous and harmful substances such as antibiotic, aromatic hydrocarbon, heavy metal, adds municipal sludge and feces of livestock and poultry The factors such as stench is difficult to, and crop material volume is big, fertilizer efficiency is low, cause making full use of these garbages and must carry out harmless Change processes, and therefore cost improves.Carry out for many years although reclaiming organic waste utilizes, also achieved some achievements, but At present the utilization rate of China's organic waste does not only improve with comparing several years ago, decreases on the contrary, crop straw burning and intensive The pollution of environment is on the rise by the fowl and animal excrement that change cultivation brings, and soil organic matter content is more and more lower, and carbon element content is more Coming the fewest, and carbon can not complete the loop jump at nature, therefore farmland quality is deteriorated year by year, have impact on China's agriculture The sustainable development of industry.
The processing method processing these rubbish the most frequently used at present has landfill method, burning method and composting process.These three method is again There are some drawbacks, such as landfill method, floor space is big, and soil, subsoil water and air are easily caused secondary by the rubbish after landfill Polluting, surrounding enviroment easily grow mosquito, emitting offensive odor, simultaneously serious waste resource;Burning method: burn remaining slag and also to fill out Burying, cause secondary pollution, seriously in burning process, easily generation two English, Mercury in Battery steam cause atmospheric pollution, money Source can not get recycling;Although composting process obtains resource reutilization, but heavy metal can not get controlling, and impurity is more, processes the time Very long, place is big.In a word, current organic solid waste treatment technology level is relatively low, is difficulty with innoxious, the resource of rubbish, Let alone industrialization.
Subcritical water often refers to temperature compressed liquid water between 180 DEG C-350 DEG C, the H in water+And OHˉClose to weak acid and Weak base, has the function of acid catalysis and base catalysis, and the dielectric constant of subcritical water is substantially reduced and has super ionization property, polarity Reduce, there is dissolved organic matter and the super dissolution characteristics of inorganic matter simultaneously, additionally there is excellent mass-transfer performance and environmental protection Etc. advantage.Utilize subcritical water can make the cellulose family in rubbish, lignin, starch based, oils, organic toxic substance and Partly plastics etc. decompose, and make macromolecular substances be degraded to crop easily by the little molecules of fatty acids of crop utilization, protein, ammonia The Organic substance such as base acid, polypeptide and oligosaccharide, therefore subcritical water technology utilize fertilizer efficiency obtained by the organic waste of town and country and Activity is higher.
Currently for subcritical water treatment technology, corresponding patent documentation also has certain report, such as Chinese patent application Number being CN201510147287, title is " Semen Maydis grit subcritical hydrolysis prepares the method for Semen Maydis polypeptide " and Chinese Patent Application No. For CN201510411800, title is " one utilizes subcritical water to produce oligopeptide and amino acid whose method from high temperature grouts ", I.e. by being heated to reflux reclaiming the residual oils and fats in high temperature grouts, use subsequently subcritical water hydrolysis grouts, by centrifugation, decolouring, Ultrafiltration, nanofiltration separation, spray drying obtain oligopeptide and aminoacid respectively.This method needs heating due to preamble processing, follow-up Add work step be also performed to be centrifuged, decolour, ultrafiltration, nanofiltration separation, the tedious steps such as spray drying, therefore energy consumption is relatively big, relatively costly. China Patent No. is CN201520050669, and title is " the subcritical water reaction unit preparing fertilizer " and Chinese patent application Number being CN201520051115, title is " using feces of livestock and poultry to prepare the subcritical water reaction unit of fertilizer ", this method Disclose a kind of subcritical water reaction unit using feces of livestock and poultry to prepare fertilizer, but the method processing equipment is single, only Processed by reactor connection, and only add simple churned mechanically mode by being passed through high-temperature steam when processing, have Machine thing processes not thorough, and the product of post processing does not carry out follow-up utilization;China Patent No. is CN201510155926, Title is " the Subcritical Water Extraction agent of polyphenols and extracting process in a kind of lotus solid waste ", and this method is to utilize Subcritical water makes extractant, extractant by water, citric acid or malic acid or both mixing, Vc, sodium sulfite by certain weight Amount number composition, enriches the content of extractant, and processing cost is higher.Additionally also have some patent literatures by subcritical Organic solid waste is processed as the method for imflammable gas or other liquid by water.
Above-mentioned document is not the most reported about the method being added follow-up aerobic fermentation by subcritical water organic waste is raw Produce into a whole set of processing procedure that high activity little molecule richness carbon is fertile;And want intelligent processing method in processing procedure, reduce cost, fertilizer The multipurpose of material converts, and is all to use subcritical water to process organic waste to add the problem that aerobic fermentation needs solve.
Summary of the invention
For defect of the prior art, it is an object of the invention to provide a kind of high activity little molecule richness carbon fertilizer and preparation thereof Method;Described preparation method specifically from utilize subcritical water process organic solid waste to process product, to making good use of aerobe fermentation process Carry out tail product After-ripening, be prepared as fully to supplement organic matter for soil, improving soil aggregate, loose activated soil Earth, the high activity little molecule richness carbon fertilizer of recovery soil health vigor;Whole process energy conservation is efficient, compact in design, Environmental Safety, Fertilizer activity is high.
