Description
Technical field
The present invention relates to field of garbage disposal, specifically a kind of organic waste deodorizer and preparation method thereof.
Background technology
Rubbish is the garbage produced in people's daily life and production process, because output is large and complicated component is various, the process problem of decrement, deodorization has brought very large difficulty.The technology of current process house refuse mainly contains sanitary landfills, burning and compost etc., wherein composting technology be that organic waste is innoxious, the key technology of minimizing and resource, and microorganism is the main body of compost fermentation.
In addition, utilize microorganism to carry out deodorization beyond doubt most environmental protection, it decomposes by biological oxidation stink source of eliminating, and deodorization is in extensive range, and is suppressed the quantity of anaerobe or other harmful bacteria by biological inoculum balanced action, makes it produce stink.Generation and the breeding of taking off Organic substance, stopping Organic substance generation ammonia and hydrogen sulfide (stink) and harmful bacteria is divided by microorganism and useful mushroom etc.
Microbial deodorant compares with traditional chemical product.Often kind of chemical products is all product with strong points, when meeting other complicated chemical matrix, just can lose efficacy; After using chemical products, in rubbish, always have chemical residue, it may bring side effect or new pollution; Use chemical products can mask malodors, but can not change the generation of stink or stop it to distribute.Microbial deodorant technology utilizes natural decomposition and the positive biochemical action in catabolic process, can not produce the problems referred to above.Microbial deodorant is compared with traditional biological cleanser.Microbial deodorant technology greatly can dispel stink, makes the rapid metabolism of organic substance, reduces bulk of solid matter, the contaminated material of fast purification.
Microbial deodorization method has the incomparable superiority of traditional method, as high in treatment effeciency, non-secondary pollution, required equipment are simple, easy to operate, low cost, management maintenance are convenient, and its development potentiality and application prospect are quite widely.

First select 6 garbage chutes (about 130 tons of/day quantity of refuses) to test, be divided into two groups: experimental group and contrast matched group, often organize 3 garbage chutes.Experimental group: continuous 7 days, transmits mouth respectively with organic waste deodorizer prepared by the embodiment 1-3 after spray pattern (as far as possible evenly) input dilute with water at the rubbish of 3 garbage chutes.Contrast matched group: continuous 7 days, transmits mouth respectively with organic waste deodorizer prepared by the comparative example 1-3 after spray pattern (as far as possible evenly) input dilute with water at the rubbish of 3 garbage chutes.
The compost of organic waste is produced and is carried out according to soot common process completely.Through the experiment of one-period (7 days), the specific experiment result of two groups please refer to table 1; Wherein odor concentration adopts triangle odor bag method (GB/T14675) to measure, ammonia adopts sodium hypochlorite-salicylic acid spectrophotography (GB/T14679) to measure, hydrogen sulfide adopts MBAS spectrophotometry (GB/T11742) to measure, and is imbedded in junk-heap body by rubber tube during sampling.Residential block air standard adopts " ambient air quality " (GB3095-2012).
The experimental result of table 1 liang group
As shown in Table 1:
Experimental group: rubbish is after 1-2 days, temperature rises to rapidly 40-50 DEG C (ambient temperature is 6-8 DEG C), ferment very fast, after beginning 20 hours, percolate starts to ooze out, garbage odor straight line drops to basic odorless, and wherein the concentration of ammonia, hydrogen sulfide and sulfur dioxide all can meet residential block air standard, and clearance can reach more than 95%; Rubbish heap high from fermentation before about 1.5 meters be down to about 0.6 meter, sedimentation rate about 60%.
Contrast matched group: rubbish will start to heat up after 2-3 days, temperature is 35-45 DEG C (ambient temperature is 6-8 DEG C), stink reduces but very comparatively large to some extent, and wherein the concentration of ammonia, hydrogen sulfide and sulfur dioxide all can not meet residential block air standard, and clearance is only below 80%; Rubbish fermentation is thorough, piles high before fermentation about 1.4 meters and is down to about 0.9 meter, sedimentation rate about 40%.
