Description
Technical field:
The invention belongs to organic solid castoff handles and the comprehensive utilization field.
Background technology:
At present, both at home and abroad, organic solid castoffs such as house refuse are carried out stabilization processes all adopt long-term compost fermentation method, the time is 20 days-30 days; Though its result has reached traditional stabilisation, a large amount of worm's ovums and disease bacterium have been killed in no longer secondary fermentation heat production; But negative effect also clearly; Because of long-term compost fermentation, produce a large amount of greenhouse gases and volatility toxic and harmful; Especially foul gas is very serious to the pollution of environment, recruits to the mosquitos and flies parasitism, easily produces epidemic infectious diseases.Because long-term compost fermentation has exhausted 70% above nutriment, has accumulated a large amount of inhibitory substances; It is microbial toxin; Harmful heavy metal can not be decomposed, volatilize by microorganism.Because organic matter decomposes volatilization, and makes waste reduction, the relative cumulant of heavy metal is increased.Compost is because of existing a large amount of microbial toxins and the harmful microorganism that is not killed; Add a certain amount of heavy metal, thereby lost the value of making fertilizer.Developed country allows greening to use at the beginning; As soil conditioner.Afterwards,, permitted no. greening usefulness, can only do the floating head soil of sanitary landfills factory owing to evade ecological risk.Because long-term compost fermentation easily produces a large amount of inflammable gases; As methane, carbon monoxide, hydrogen etc.; Burning and blast often take place.
Summary of the invention:
The objective of the invention is to solve organic solid castoffs such as house refuse,, reach the series of negative effect that traditional stabilisation is brought by compost fermentation; With the traditional long-term compost fermentation method of chemical stabilization processing method replacement fast, overcome the negative effect of compost fermentation; Its concrete approach is the method by the solid ammonia of chemical catalysis degraded; Concrete technology comprises the solid ammonia of chemical catalysis hydrolysis; The solid ammonia of super-pressure carbonated drink thermal cracking; Solid ammonia is decomposed in the microwave chemical inducing catalysis; The solid ammonia of plasma chemistry catalytic pyrolysis; The solid ammonia of the expanded thermal cracking of HTHP mechanochemistry catalysis.The chemical catalysis degradation temperature is 200 ℃-500 ℃, and pressure is 1.0MPa-10.0MPa, and the reaction time is 2min-2h.
The solid ammonia of chemical catalysis degraded divides two steps to carry out, first step makes the organic matter of easy degraded comprise kitchen excess, useless fruit, paper, woody and herbaceous plant residue and discarded object, animal's leather, the natural fiber of dry goods, staple fibre, non-plastics class chemical synthetic fiber.Chemical composition is cellulose, hemicellulose, pectic substance, lignin, starch, fat, mucopolysaccharide, protein.The first step chemical catalysis is degraded into little molecule carbide; Be the carbohydrate of different molecular weight, as glucose, wood sugar, mannose; Glycitols is as glycerine; The alditol acids is as glucuronic acid, galacturonic acid; Organic acid is as formic acid, acetate; Fatty acid; The phenylpropyl alcohol alkanes is as lilac base phenylpropyl alcohol alkane, guaiacyl phenylpropyl alcohol alkane, para hydroxybenzene propane; Peptide class, amino acids, Ammonia that little molecule nitride is a different molecular weight.Second step; Above-mentioned little molecule carbide and little molecule nitride carry out the Maillard reaction of molecular rearrangement; It is the solid ammonia react of catalysis, form the little molecular carbon nitrogen compound of different molecular weight, comprise small molecular sugar ammonium, sugar alcohol ammonium, uronic acid ammonium, organic acid ammonium salt, glycerine ammonium, aliphatic acid ammonium, amino lilac base phenylpropyl alcohol alkane, amino guaiacyl phenylpropyl alcohol alkane, the amino para hydroxybenzene propane of different molecular weight.Second step, the reaction temperature of the solid ammonia of molecular rearrangement catalysis is 70 ℃-300 ℃, and pressure is 1.0MPa-3.0MPa, and the reaction time is 0.5h-4.0h, Gu ammonia react divides solid ammonia of endogenous and exogenous solid ammonia; The solid ammonia of endogenous refers to utilize the contained ammonia of organic waste itself or amino-compound such as peptide and the solid ammonia of amino acid; Exogenous solid ammonia is in order to increase the nitrogen nutrition of organic nitrogenous fertilizer, to add liquefied ammonia or ammoniacal liquor and strengthen solid ammonia exogenous solid ammonia.Gu the calculating of solid ammonia amount in the ammonia process; With the solid ammonia of glucose unit in cellulose, the starch composition is example, and a glucose unit is fixed amino a calculating, and fixing nitrogen is that glucose is by 6% of total amount.The multipotency of glucose unit is fixed three amino, and high nitrogen content reaches 18%.
Totally three kinds of first step chemical catalysis degraded catalyst system therefors; Acidic catalyst, base catalyst, electrochemical catalyst.Acidic catalyst comprises inorganic acid example hydrochloric acid, nitric acid, sulfuric acid, hydrofluoric acid, fluosilicic acid, sulfamic acid; Organic acid comprises VFA and non-volatile organic acid; Acidic oxide such as sulfur trioxide, sulfur dioxide, strong acid weak base salt such as ammonium sulfate, magnesium sulfate.Base catalyst comprises that oxide, hydroxide, weak acid strong alkali salt, the Ammonia of alkali metal, alkaline-earth metal comprise hydride, hydroxide, the organic amine of ammonia, the oxide of alkali metal, alkaline-earth metal, hydroxide comprise potassium hydroxide, NaOH, magnesium hydroxide, sodium oxide molybdena, potassium oxide, magnesia, weak acid strong alkali salt comprises potash, saleratus, magnesium carbonate, sodium acetate, potassium acetate etc.The hydrogen peroxide adduct of ammonia, hydroxide, organic amine comprise ammonia, ammonium hydroxide, and organic amine comprises methylamine, ethamine, propylamine, butylamine, quaternary amine.Electrochemical catalyst comprises acid water and the alkaline water in the brine electrolysis, the hydrochloric acid of the generation that electrolyzes table salt, NaOH, clorox etc.
The catalyst that utilizes organic waste self to produce through the chemical catalysis degraded; For example deacetylation produces acetate in the hemicellulose degradation process; Demethoxylation produces formic acid in the lignin degradation process; In the protein degradation process, produce amino acid, all can not add catalyst, cry the autocatalysis agent as catalyst at other; Also be the endogenous catalyst.Organic waste is the hydrolysis acidification stage through the starting stage of anaerobic fermentation, produces a large amount of mixed organic acids and makees catalyst; Also cry autocatalysis or endogenous catalysis.Make catalyst by the organic acid that self produces and have the saving cost, without outsourcing; But the catalyst reaction time is oversize, reaches more than ten hours, causes equipment size very big, and uneconomic problem is also arranged.The acidic catalyst consumption with pH meter, is 0.1%～10% of organic total amount; Base catalyst is 0.1%～10% of organic total amount in hydroxide ion.
The solid ammonia react catalyst system therefor of the second step molecular rearrangement is that base catalyst is identical with the base catalyst of first step chemical catalysis degraded; Dosage is controlled 6-9 with the pH of solid ammonia material.
Stabilization processes flow process, the method for the solid ammonia of chemical catalysis degraded specifically is that organic waste such as house refuse reclaim through broken bag, sorting, impurity elimination, resource earlier, and it is broken that the organic matter of purifying accounts for 95% o'clock elder generation, then theory of evolution catalytic degradation jar.Add catalyst, have add earlier and after divide in addition; Add earlier, need catalyst evenly mixed with organic matter with mixer, and then theory of evolution catalytic degradation jar, after add catalyst, for earlier with organic matter after fragmentation, theory of evolution catalytic degradation jar; Then, outside degraded jar, add a cover catalyst circulation device, liquid catalyst is sprayed into the top of degraded jar through shower nozzle with high-pressure pump, the whole bed of material of flowing through, diafiltration is flowed back to catalyst tank again to pot bottom, and reciprocation cycle makes catalytic degradation reaction even.Catabolite in two sub-sections; One is the liquid part, and one is solid portion.For the liquid part, behind the solid ammonia catalyst of adding, carry out solid ammonia react, PH is controlled at 6-9, and the reaction time is 0.5h-4h, and temperature is 70 ℃-300 ℃, and pressure is 1.0MPa-3.0MPa.After reaction is finished, carry out evaporation and concentration through the quadruple effect thin film evaporator.Tail gas after thermal source is degraded with chemical catalysis.Be concentrated to solid content and be concentrated to 40%-70% by 3%-5%.Can make organic nitrogen liquid fertilizer and organic nitrogen composite liquid fertilizer by adjusting the proper ratio of nitrogen, phosphorus, potassium nutrition; Also can be with after ammonia dehydration granular material mix admittedly, drying and dehydrating, the organic nitrogenous fertilizer or the organic nitrogen composite fertilizer of making solid.Can be with endogenous solid ammonia, only adjust pH value and do not add liquefied ammonia and ammoniacal liquor in addition and make common organic nitrogenous fertilizer.Also can add in addition liquefied ammonia and ammoniacal liquor carry out exogenous solid ammonia mix again phosphorus, potassium and in, trace element produces high nutrient organic nitrogen composite fertilizer.
Organic matter in the house refuse is degraded into little molecule carbide and nitride by chemical catalysis; Through molecular rearrangement, the solid ammonia of catalysis generates carbon nitrogen compound, reaches stabilisation then.Its principle is in the carbon nitrogen associative key in the carbon nitrogen compound, and the atomic radius of carbon is less than the atomic radius of nitrogen, so the electronegativity of carbon big than nitrogen, electron cloud deflection carbon atom one side makes nitrogen-atoms be the cation state, presents positive charge.The microorganism surface is a negative electrical charge, both contacts, and microorganism just is suppressed, or is killed, and can not continue breeding, also with regard to unfermentable heat production, thereby has reached stabilisation.In addition, little molecular carbon nitrogen compound considerable part is water soluble state, and its concentration is much larger than microbial cell liquid concentration, and the two contact makes that moisture content oozes in the microbial cell liquid; Thereby microorganism is lost one's life, can not survive.Because above-mentioned two aspects make organic waste reach rapid stabilization by the chemical method of the solid ammonia of chemical catalysis degraded.
Good effect of the present invention is to reach rapid stabilization by the solid ammonia of chemical catalysis degraded.In this process, there is not secondary pollution to emit, there are micro-formic acid and acetate in the tail gas, not the pollutant that discharges forbidden of national regulation, absorb, be neutralized into the calcium formate and the calcium acetate of indissoluble with lime by the absorption tower, turn back in the fertilizer, replenish moderate-element calcium.Because stabilisation does not produce stench, makes treatment plant not have the mosquitos and flies parasitism, clean very much.Because the processing time is short, makes the treating apparatus floor space little, 1/4th of not enough compost occupation of land.
Good effect of the present invention shows that also the organic nitrogenous fertilizer of generation and organic nitrogen composite fertilizer change into organic nitrogen with inorganic nitrogen, and makes organic and inorganic part by the solid ammonia of Maillard reaction, forms integrated.Break fertilizer industry and can only lean on solid ammonia of carbon dioxide and the acid traditional mode of ammonia admittedly.The present invention makes fertilizer industry increase new kind; Organic nitrogenous fertilizer and organic nitrogen composite fertilizer; Make the carbon nitrogen balance, absorbed together, fundamentally avoided owing to use the nitrate of the agricultural product that chemical fertilizer causes, the chemical residual of nitrite merely by the crops root system.
Because during organic nitrogenous fertilizer and organic nitrogen composite fertilizer belong to, depot fertilizer, plant recovery of nutrient is brought up to 50%-60% by the 20%-30% of pure fertilizer.Avoided the ammonia loss by volatilization of pure fertilizer in soil; Simultaneously also avoided nitrated, denitrifying volatilization loss; Also avoided pure fertilizer since in soil rapid and natural flow to leaching loss in deep subsoil and the rainwash; And then polluted underground water and surface water resource have been avoided.Because the plant recovery of nutrient height of organic nitrogenous fertilizer and organic nitrogen composite fertilizer, fertilizer efficiency period is long, and lower content just can reach the high level of pure fertilizer, and the production cost of manufacturer is reduced.The organic nitrogenous fertilizer that the peasant has bought has increased output because plant recovery of nutrient height, economical has reduced input.To corn, the test that tomato etc. are done, demonstration show in the Jining City, Shandong Province; Organic nitrogen composite fertilizer does contrast test with pure fertilizer composite fertilizer and draws, and saves nutrient up to 50% than pure fertilizer, makes peasant's increasing both production and income.Because inorganic nitrogen changes into organic nitrogen, microorganism can not be destroyed carbonnitrogen bond.The interconnected oxo bridge key of the sugar unit of can only degrading makes molecular weight more and more littler.What crop root directly absorbed is aminosugars, has avoided the unbalance chemical residual of carbon nitrogen.What technology of the present invention was produced is the Yield increasing type green fertilizer.In the world, especially developed country is forbidden to use chemical fertilizer for the production of organic farm products, can only use traditional fertilizer, and output is to use 1/3rd of chemical fertilizer.The organic nitrogen composite fertilizer that the present invention produced is waiting under the nutrient condition, and relatively fertile with the pure fertilizer compound, output will exceed 20%-30%.
