(1) rubbish biological deodorizing degradation principles
Directly absorb and decompose malodor molecule
As it is shown in figure 1, after effectively compound microbial inoculant is rendered in rubbish and foul smell space, malodor molecules meeting therein Being removed in the moisture dissolving in microbial inoculum, the malodor molecule having dissolved is neutralized by microorganism secretion material in preparation, with Microorganism can absorb the established malodor molecules of decomposition, reduces the concentration of malodor molecule, mitigates the stench feelings of environment, below Divide and list the reaction using sulfur-bearing (S), nitrogen (N) and other hydrocarbon oxygen (CHO) malodor molecules:
2CH3SCH3+9O2+2e-→4CO2+6H2O+SO4 2-
4NH3+9O2+4e-→4NO3 -+6H2O
2CH3OCH3+6O2→4CO2+6H2O
The mechanism of whole decomposition smell molecule includes the following stage:
(1) malodor molecules spreads in the environment
(2) malodor molecules dissolves and suspends in atmosphere or in the microbial inoculum agent moisture film of the surface of solids
(3) partly malodor molecule is soluble in water
(4) partly malodor molecule is nothing by metabolin (such as Vitamin C, E and the polysaccharide etc.) oxidation Decomposition of microorganism secretion Malodor molecules
(5) partly malodor molecule is decomposed into odorless molecule by the external ferment of microorganism
(6) through infiltration or microorganism active transport effect, malodor molecule is absorbed by the micro-organisms
(7) malodor molecule decomposes in microbial body, product odorless
So in the process effectively compound microbial inoculant to malodor molecule, direct row dissolves, chemical combination and decomposition remove Smelly effect.
(2) degraded organic matter in garbage
As in figure 2 it is shown, the organic matter in rubbish is acted on, first by the microbes in effectively compound microbial inoculant The outer ferment of permeation body and the effect of acidolysis, be changed into simple product such as complicated organic matter；Amino acid, organic acid, monose, double Sugar, aliphatic acid and glycerine etc., re-absorption enters intracellular, for synthetic cell matter and maintain needed for cell activities, including Following biochemical reaction:
Protein → amino acid
(C6H12O6)n→C6H12O6+C12H24O12
Aliphatic acid → fat acid+glycerine
Owing to the product of microorganism generation effect in EO-L effective microbe microbial inoculum is mainly the simple molecules of odorless such as Alcohols, carbon dioxide and moisture etc., so will not impact to environment.Additionally the organic component in rubbish is by progressively Decomposing, when the chance of putrefactivebacteria effect and impact obtain control, the volume of rubbish itself also can constantly reduce thus reach rubbish Rubbish reduced training.
(3) bacterium, the effect of germ are suppressed
When effectively compound microbial inoculant is devoted in environment, the actinomyces in microbial inoculum can produce other bacteriums of suppression Natural antibiotics；The secretion of the acid-producing bacterias such as lactic acid bacteria can constrain the growth of other bacteriums, and therefore effective microbe exists Place, other putrefactivebacteria and pathogens etc. cannot grow, and the pupa, maggot hatching and the suppression pathogenicity that suppress mosquitos and flies micro-simultaneously Biological breeding, can solve the generation of rubbish secondary pollution, it is achieved innoxious from root.
Effective microbe microbial inoculum action effect
1) accelerate fermentation to decompose, reduce the volume piling up pollutant at short notice, thus reduce the total amount of pollutant.
2) suppress the growth of putrefactivebacteria, improve the decomposition approach of organic matter, the burst size of minimizing ammonia and hydrogen sulfide and ammonia The generation of class material.
3) owing to effective microbe fermentation can consume moisture, thus reduce the quantity that pollutant produces, also improve The water quality of pollutant, reduces succession.
4) suppress pupa, the maggot hatching of mosquitos and flies, reach to reduce the long-range effect that mosquitos and flies multiplies, reduce disease.
5) suppress the breeding of pathogenic microbes, prevent the generation of disease.
6) process of landfill soil and regeneration is promoted, it is achieved innoxious.
2. pyrolytic technique
Under dilute oxygen or anoxia condition, utilize inflammable substance in house refuse as pyrolysis fuel 350 DEG C- Passing through thermal chemical reaction under the temperature conditions of about 380 DEG C, macromolecular substances resolves into flammable relatively small-molecule substance (can Combustion gas, fixed carbon, tar etc.) thermochemical study technology.
(such as vial, stone, gold after the noncombustible matter part of bulk in simple sorting, removal rubbish for the rubbish Belong to), the rubbish of remaining part is sent into pyrolysis oven pyrolysis by feeder, utilizes the inflammable substance conduct in house refuse The fuel of pyrolysis, the temperature of 350 DEG C about-380 DEG C, carries out thermal chemical reaction, discharges heat and be converted under the conditions of dilute oxygen Combustible gas and the solid residue of a small amount of stable in properties；The flue gas producing after pyrolysis by the cooling of alkali lye spraying box, dedusting, Depickling, processed；Further dedusting, the effect removing tar removing through type tar purifier；Absorption work(through activated carbon again The poisonous and hazardous materials such as the heavy metal in flue gas, two English can be removed；Flue gas acts through chimney through air-introduced machine again Carry out qualified discharge.

Facts have proved owing in pyrolytic process, flue gas residence time in stove is longer, and through the filtration of waste layer, heat Solve the CI ion major part absolutely producing to be attached on lime-ash, directly reduce and inhibit the generation amount of two English；Flue gas is again Through the suction-operated of activated carbon, effectively eliminate the poisonous material in evil of existing two English, the heavy metal etc. in flue gas, reach Purpose to harmless treatment.
5), recycling is abundant
The plastic bottle that contains in a, house refuse, discarded metal etc. are due to convenient sorting, and the income of recycling is relatively High；Equipment operation personnel actively carries out sorting and sell the mesh that salvage station reaches resource recycling during feeding 's.
In b, villages and small towns house refuse, category of glass accounts for the 5 10% of rubbish gross weight as a kind of non-flammable inorganic matter, Pyrolytic process should be avoided into stove as far as possible, in order to avoid reducing refuse pyrolysis treatment effeciency；Therefore category of glass must be strict with to enter Stokehold sorts out, and the glass selected can sell the recycling that salvage station carries out resource.
Complex microorganism and pyrolytic technique deodorizing minimizing small towns refuse disposal system, be application complex microorganism deodorizing fall Solve and be pyrolyzed a kind of new technology that carbonization principle processes small towns rubbish.This technology preferably has the advantage of composting process and burning method Machine combines, and changes the single effect of the waste disposal methods such as traditional landfill, compost, burning, has put into practice and used garbage as resource Utilize this final goal to control the Advanced Idea of garbage disposal overall process.
Its great advantage is:
1. played the pardon of landfill method and the advantage of relatively low processing cost, but a large amount of soil need not have been occupied and will not produce The raw draining that oozes pollutes, and stench and the raw four pests of evil affect the secondary pollutions such as environment.
2. played composting process and organic principle (such as kitchen excess, plant etc.) available in rubbish has been converted into the excellent of organic fertilizer Point, but it is relatively low to overcome composting process volume reduction treatment rate, processes the cycle longer, and can not process not biodegradable organic matter The shortcoming of (such as synthesis of organic substance such as plastics).
3. played the advantage to garbage fast and harmless process and heat integration for the burning method, but can effectively suppress The secondary pollution that the pernicious gases such as the dioxin that burning method easily produces and heavy metal cause.
