Abstract
The invention relates to a method for preparing an organic fertilizer from municipal domestic waste, which comprises the following steps: carrying out rough separation, bag breaking, magnetic separation and screening; pulverizing the oversize to make RDF (refuse-derived fuel); degrading organic materials in the screen; dehydrating by extrusion, baking, screening, pulverizing and proportioning; adding proper amounts of other auxiliary materials into the degraded organic materials, carrying out energy loading, granulating, baking, screening and bagging the finished product. The invention solves the problem that municipal domestic waste is difficult to treat, prepare an organic fertilizer which can quickly improve soil and has strong functions of moisture retention, drought tolerance, disease and pest resistance, stress tolerance and lodging resistance, recycles the resources, and has the advantages of low investment, small occupation area, short treatment period and low operating cost.
Description
Technical field:
The present invention relates to a kind of recycling treatment process of domestic waste, particularly a kind of is the method for feedstock production fertilizer with the domestic waste.
Background technology:
Chinese city domestic refuse complicated component comprises waste paper, clothing cloth, dregs, metal, glass, rubbish from cooking etc., is difficult to handle effectively, and composting process in the present stage technology of garbage disposal, directly all there are certain defective in burning process, landfill process.For example for landfill disposal, not only floor space is big, and exists secondary pollution such as polluted source air, and at present a lot of big cities have been difficult to find suitable landfill place; Composting process, long processing period, and produce high-concentration waste water, be difficult to handle contaminate environment; Direct burning process, there are smoke pollution in construction cost and operation cost height, and consumes energy.
Summary of the invention:
Technical problem to be solved by this invention is: providing a kind of is the method for feedstock production fertilizer with the domestic waste.Overcome the defective of prior art, the invention provides a kind of is the method for feedstock production fertilizer with the domestic waste, has promptly realized the processing of domestic waste, can produce organic fertilizer again.
Technical scheme of the present invention is:
A kind of is the method for feedstock production fertilizer with the domestic waste, it is characterized in that: comprise the following steps: that domestic refuse carries out ragging earlier, recoverable material stone and plastics bag do not sort out with the combustible material of bulk and other bulks; The plastics bag broken bag breaks the plastics bag that domestic refuse is housed, and the sack materials inside is scattered, to make things convenient for subsequent disposal; By magnetic separation ferrous metal is sorted out; Sieve, sieve is the innoxious landfill of inorganic material down again, and organic materials carries out degradation treatment in the sieve, and the screen overflow material is pulverized and made RDF domestic refuse derivatived fuel; Organic material carries out degradation treatment in the sieve, by using steam and catalyzer, its catalyzer is: dilute sulphuric acid, consumption: the ratio of the organic material of catalyzer and rubbish is 1%, organic matter in the rubbish is degraded, under 1.1MPa and 185 ℃, degraded 1.5 hours, microorganism and toxic substance are removed, and with carbohydrate and humic-acid kind that macromolecular organic matter degradation becomes micromolecular plant easily to absorb, wherein: the complete gelatinization of starch also becomes dextrin, protein degradation is micromolecular protein and each seed amino acid, poly-pentose is degraded to water-soluble various polysaccharide and uronic acid, pectin, polysaccharide is degraded to polysaccharide aldehyde, as the base-material use of fertilizer; The back material of degrading is carried out extrusion dehydration, oven dry, screening is pulverized, and adds other suitable auxiliary materials in the organic materials after degraded, prepares burden, and granulates oven dry, screening, finished product pack.
2, technology according to claim 1, it is characterized in that: during degraded, reactor material loading 30 minutes, reactor is under 1.1MPa and 185 ℃, degraded 1.5 hours, microorganism and toxic substance are removed, macromolecular organic materials is degraded into the organic matter that micromolecular plant easily absorbs, be incubated 30 minutes, draining 120 minutes.
The invention solves the difficult problem that domestic waste is difficult to handle, but make quick improvement soil, the organic fertilizer of extremely strong water conservation, drought resisting, disease and insect resistance, degeneration-resistant, function resistant to lodging is arranged, realized recycling, investment and floor space are little, and the processing cycle is short, and running cost is low.
Description of drawings:
Fig. 1 be a kind of be the processing method block diagram of feedstock production fertilizer with the domestic waste.
Embodiment:
A kind of is the method for feedstock production fertilizer with the domestic waste, comprises the following steps:
(1) ragging: the combustible material and the unclassified stores of bulk are sorted out;
(2) broken bag: the plastics bag that domestic refuse will be housed breaks, and the sack materials inside is scattered, to make things convenient for subsequent disposal;
(3) magnetic separation: ferrous metal is sorted out;
(4) screening, sieve is the innoxious landfill of inorganic material down, and organic materials carries out degradation treatment in the sieve, and the screen overflow material is pulverized and is made RDF;
(5) degraded: the organic matter in the rubbish is degraded by using steam and catalyzer, under 1.1MPa and 185 ℃, degraded 1.5 hours, microorganism and toxic substance are removed, macromolecular organic matter degradation is become micromolecular the plant easily carbohydrate and the humic-acid kind of absorption, as: the complete gelatinization of starch also becomes dextrin, protein degradation is micromolecular protein and each seed amino acid, poly-pentose is degraded to water-soluble various polysaccharide and uronic acid, pectin, polysaccharide are degraded to polysaccharide aldehyde, as the base-material use of fertilizer;
(6) extrusion dehydration is saved the energy;
(7) oven dry;
(8) screening: the material of failing to decompose in the jar of will degrading screens out;
(9) pulverize;
(10) batching: add other suitable auxiliary materials in the organic materials after degraded, carry out energy and load;
(11) granulate;
(12) oven dry;
(13) screening;
(14) finished product pack.
