Abstract
The present invention relates to a processing method of urban domestic garbage. Organic substance powder which is sorted and taken from the urban domestic garbage is refined into granules; after sulfuric acid as an additive and phosphide are added and is thoroughly mixed for agening and bulking spray burst processing to obtain powdery pitchy organic substances; after drying and sieving processing, the pH value is regulated; nitrogen, phosphorus and potassium nutritional ingredients are added and uniformly mixed; after granulation and air drying, the mixture is weighted and packed. When the method of the present invention is used, organic substances can be sufficiently aged and degraded, and the problem that products generate secondary pollution is solved; after the bulking spray burst, big and hard organic substances are crushed; thus, garbage resources are fully utilized and macromolecular chains of fibre substances are cut off so that the products can be easily absorbed. The phosphide is converted into PO3 <-1> which can adsorb and contain heavy metal to cause the heavy metal to be passivated so that the harm caused by the heavy metal on soil and crops is reduced; through sulfuric acid, organic substances can react to generate monosaccharide and polysaccharide, and to provide conditions for the conversion of various kinds of humic acid, so the organic substance quality is greatly enhanced.
Description
Technical field
The present invention relates to a kind of treatment process of domestic waste.
Background technology
Utilize the method for the processing of organic composition in domestic waste compoiste fertilizer a lot of at present, conclude and get up to have substantially two types of composting technology and biofermentation techniques.Just adopt the various working method analysis-by-synthesis of biofermentation technique type to be not difficult to find out that at present still existence is following main not enough: abundant inadequately to the degraded of the organic composition in the rubbish, even some difficult organic substance that becomes thoroughly decomposed is by residual, not only influence the fertilizer efficiency of finished product, also have the practical problems that produces secondary pollution.More general problem is the processing means that lack in the various working methods heavy metal composition in the rubbish, and the heavy metal composition has caused the attention of relevant department to the direct harm of soil and farm crop generation.
Summary of the invention
The present invention produces the above-mentioned technical problem that exists in the method for fertilizer in order to solve the known domestic waste that utilizes, and propose a kind of organic substance degraded fully, fertilizer efficiency is higher and can obviously reduce in the compoiste fertilizer heavy metal to the method for utilizing preparing composite organic fertilizer life garbage in urban area of soil and murrain degree.
The present invention is for solving the problems of the technologies described above the following method of taking:
(1) with domestic waste through after mechanical grading removes large-scale special body size composition, through gravity preparation, selection by winnowing, magnetic separation and cooperate artificial separation to remove brick and tile ash sandstone, glass-ceramic fragment, waste plastic, ferromagnetic material and mix inorganic components, take the organic substance in the rubbish again;
(2) gained organic substance dispersion and fining being become maximum diameter is the particle of 30-50mm;
(3) add additive in granular organic substance, promptly concentration is the sulfuric acid of 10-25% and phosphorus content at 16% finished product phosphate fertilizer, is respectively 100 with the weight ratio of garbage organism matter: 2-8 and 100: 10-20, and thorough mixing.
(4) the particulate state garbage organism matter that will be mixed with above-mentioned additive is carried out maturation process, and condition is that to feed temperature in the high temperature and high pressure kettle be 165-200 ℃ water vapour, pressure 0.7-1.1Mpa, dwell time 1-2 hour.
(5) the particulate state garbage organism matter after the maturation process is carried out the quick-fried processing of expanded spray, chocolate powdery garbage organism matter, spray that still outlet air pressure is 0.3-0.45Mpa when quick-fried.
(6) the chocolate powdery garbage organism matter after the quick-fried processing of expanded spray is adopted the oven dry of direet-heating type hot dry wind handle, temperature 90-130 ℃, air quantity 5000-8000m
3/ h, water content ranges 20-25% sieves in the time of oven dry, and getting the following chocolate powdery garbage organism matter of 30 orders is material to be processed.
(7) add magnesium oxide and/or calcium oxide in material to be processed, adjusting its pH value is 6.5-7.5.
(8) be to add nitrogenous, phosphorous, potassic inorganic nutrients and uniform mixing in the chocolate powdery garbage organism matter of 6.5-7.5 at pH value, total inorganic nutrients content accounts for total amount 15-25%, nitrogen content 8-13% wherein, phosphorus content 5-8%, potassium content 4-9%.Nitrogenous in the operation, phosphorous, to contain the potassium inorganic nutrients can be its corresponding fertilizer, is respectively 100 with the weight ratio of garbage organism matter: 15-20,100: 15-20 and 100: 8-10.
(9) uniform mixing is had nitrogenous, phosphorous, as to contain potassium inorganic nutrients powdery garbage organism matter granulation after, under low temperature, big air quantity environment, dry, its water content is remained in the 10-15% scope, bake out temperature 65-90 ℃, air quantity 5000-8000m
3/ h.
(10) weighing and bagging after the granulation.
The present invention can also take following working method:
Described garbage organism matter comprises pericarp, shell, vegetables root leaf, kitchen food garbage and animals and plants rubbish.
Describedly pack particulate state garbage organism matter into high temperature and high pressure kettle when carrying out maturation process, in still, feed the pressurized air that can in material, form air flue.
Described when particulate state garbage organism matter is carried out maturation process, the liquid effluent of collecting the high temperature and high pressure kettle sound of rain pattering is made the mother liquor of liquid fertilizer.
After the following chocolate powdery garbage organism matter of described 30 orders is adjusted pH value, add urea, monoammonium phosphate, two ammoniums, potash fertilizer and the carbon ammonium and the thorough mixing that account for material total amount 3-5% to be processed and can get agricultural nutrition soil.
Beneficial effect of the present invention and advantage are: the core of present method is to adopt the organic substance of High Temperature High Pressure slaking and the quick-fried technical finesse rubbish of expanded spray and add an amount of phosphide and sulfuric acid.Be difficult to the organic substance that becomes thoroughly decomposed and other organic substances under the High Temperature High Pressure by abundant ageing degrading, not only solved the practical problems of goods generation secondary pollution more completely, can also utilize waste resources to greatest extent, help improving the fertilizer efficiency of goods.Organic substance particle after the slaking becomes the chocolate meal by the quick-fried process of expanded spray, not only that piece is big, hard organic substance is broken and be of value to and make full use of waste resources, simultaneously also the macromolecular chain of fibrous substance disconnected for favourable its goods of small molecules chain by crop absorption.The additive phosphide is converted into PO in the High Temperature High Pressure maturing process
3 -1Plasma state can be with the heavy metal such as the P of active free state in the rubbish
b ++, Zn
++, Ni
++Deng absorption and contain passivation, greatly reduce in its goods heavy metal to the harm of soil and farm crop.Additive sulfuric acid makes organic substance reaction generate monose, polysaccharide and for the conversion of various humic acid provides sufficient condition, has improved organic quality greatly in the High Temperature High Pressure maturing process.It is short that the present invention also has process cycle, meets that refuse treatment is innoxious, minimizing, resource utilization requirement, the fertilizer of being produced or the high outstanding feature of compoiste fertilizer quality.
