Description
Technical field:
The invention belongs to this technical field of rubbish preprocess method, belong to this technical field of town refuse biology pretreatment method especially.
Background technology:
Along with economic development, municipal refuse is more and more, and the biological recovery of rubbish has become a kind of new trend, and the rubbish biological absorption method is compared with existing garbage loading embeading method, waste incineration method to have to take up an area of and lacked, and environment is not produced characteristics such as pollution.Rubbish biological reclaims and mainly to comprise the ragging operation, broken bag operation, Biological Pretreatment operation, sorting operation, fermentation procedure, secondary sorting operation, baking operation, selected operation, fertilizer operation again.Crude waste is earlier through the ragging operation, with wherein bamboo wood class packing case, rubber tyre is separated and with big part fragmentation; The rubbish that ragging is crossed carries out the broken bag processing, and the rubbish after the broken bag is carried out Biological Pretreatment, and the leakage water that Biological Pretreatment produced enters sewage disposal system, and the waste gas of generation enters exhaust treatment system; To carry out a sorting through the rubbish that Biological Pretreatment is crossed, utilize technical points such as wind-force, gravity, magnetic force, spring, shape, speed to select bamboo wood class, refuse battery, plastics, glass, lighter, metal, fabric etc. and reclaim, inorganic material such as brick and tile stone are used for the manufacturing of building material; To ferment again through the rubbish of sorting for the first time, the rubbish that fermented is again carried out the secondary sorting, sub-elect combustible and sandstone in the rubbish, tiny glass etc., the rubbish of secondary sorting is dried selected, composting.The Biological Pretreatment operation is the important operation that rubbish biological reclaims, and will be directly connected to the quality of rubbish biological recovering effect.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of new town refuse biology pretreatment method.
The technical scheme of technical solution problem of the present invention is: a kind of town refuse biology pretreatment method, add mixed bacteria in crude waste, described mixed bacteria is wood sugar alkali oxide bacterium denitrification subspecies (Alcaligenes xylosoxidans subsp) CGMCC 1.768, bacillus amyloliquefaciens (Bacillusamyloliquefaciens) CGMCC 1.1177, the Chinese inferior mutation of the inferior Dbaly yeast Chinese (Debaryomyceshansenii) CGMCC 2.1831; Her Sa yeast (Issatchenkia scutulata) CGMCC 2.1592 of diamond pattern, have a liking for keratin powder mould (Aleuisma keratinophilum) CGMCC 3.3544 that falls, Pasteur's promise card bacterium (Nocardiabrasiliensis) CGMCC 4.1128, the depositary institution of above-mentioned bacterial classification are Chinese common micro-organisms culture presevation keeping reason center.
Wood sugar alkali oxide bacterium denitrification subspecies (Alcaligenes xylosoxidans subsp) CGMCC 1.768, bacillus amyloliquefaciens (Bacillus amyloliquefaciens) CGMCC 1.1177, the inferior mutation of the inferior Dbaly yeast Chinese of the Chinese (Debaryomyces hansenii) CGMCC 2.1831; Her Sa yeast (Issatchenkiascutulata) CGMCC 2.1592 of diamond pattern, have a liking for keratin powder mould (Aleuisma keratinophilum) CGMCC3.3544 that falls, Pasteur's promise card bacterium (Nocardia brasiliensis) CGMCC 4.1128, its volume ratio that enlarges the nutrient solution mixing is 10-15:5-10:10-20:1-30:5-15:10-20.
In order to strengthen the effect of microbial pretreatment loss of weight, also can add the abnormal cocci of anti-radiation the (Deinococcus radiodurans) CGMCC 1.633 at mixed bacteria, it is 1:1-3 with the volume ratio that the expansion nutrient solution of wood sugar alkali oxide bacterium denitrification subspecies (Alcaligenes xylosoxidans subsp) CGMCC 1.768 mixes.
The expansion culture medium of the used bacterial classification of the present invention is all with reference to " CGMCC bacterial classification catalogue ".
The used mixed bacteria of the present invention contains bacterium, saccharomycete, filamentous fungi, radiation bacterium four big classes, flora intrinsic in itself and the rubbish acts synergistically mutually, through the ventilation oxygen supply, flora is a large amount of degradable organic matter in the digest and decompose municipal refuse in the process of growth fast, discharge a lot of heats simultaneously, moisture in the rubbish is evaporated in a large number, ooze drop, fully play the effect that reduces crude waste weight and volume.
The present invention compared with prior art, can economical and efficient ground remove the moisture of crude waste, the wherein organic matter of degrading makes the rubbish loss of weight after the processing reach 40-45%, thereby alleviates the rubbish weight and the volume of the sorting first time.
Description of drawings:
Fig. 1 is the flow chart of rubbish biological absorption method of the present invention.
The specific embodiment:
Below in conjunction with embodiment the present invention is described in detail.
Crude waste is earlier through the ragging operation, with wherein bamboo wood class packing case, rubber tyre is separated and with big part fragmentation;
The rubbish that ragging is crossed carries out broken bag, rubbish after the broken bag is mixed, weighs, in mixed process, add mixed bacteria, ventilation oxygen supply fermentation 5-7 days, temperature is controlled at 40-50 ℃, mixed bacteria is the 1:50-100 dilution proportion by volume, the addition of the mixed bacteria after the dilution is formed according to the water content of rubbish and organic content and is decided, be generally the 0.5-5% of rubbish weight, the leakage water that Biological Pretreatment produced is entered sewage disposal system through fermentation tank bottom tube road, and the waste gas of the generation pipeline on jar top by fermentation enters exhaust treatment system; After the rubbish that ferments weighed, be transported in a separation system and carry out sorting, rubbish weight-loss ratio=(crude waste weight-ferment rubbish weight)/crude waste weight * 100%
