Gas, not only pollutes to surrounding environment, while causing serious harm, foul smell and organic exhaust gas to health and ecological environment
Improvement increasingly paid close attention to by people.
During fermentation of organic wastes, microorganism passes through metabolic activity, a portion oxidation operation Cheng Jian
Single inorganic matter, the energy for needed for biological vital movement is provided, another part organic matter be converted into organism needed for nutrition
Material, forms new cell body, microorganism is constantly bred, and in the process, releases big energy, except fraction is cytoplasm
Synthesis is provided outside energy, and remaining is released in the form of heat, micro- in organic waste high temperature fermentation stage according to document introduction
Biological oxidation is decomposed organic waste and is shown no increases in output the kJ/kg of raw heat about 420, and these heat energy are discharged with foul smell, make foul smell temperature most
It is high, simultaneously as material heap temperature is raised, to cause material moisture evaporation rate to be accelerated up to 60 ~ 70 DEG C, large quantity of moisture also with
Foul smell is discharged.
Mineral raw material such as coal, diesel oil etc. are inevitably generated the particulate matters such as flue dust, carbon monoxide in combustion
(CO), sulfur dioxide (SO2) and nitrogen oxides (NOx) etc. toxic and harmful, meanwhile, combustion tail gas can also take away amount of heat,
And this partial heat causes the waste of heat energy without utilization, aggravate the pollution to environment.
The technology for administering foul smell and organic exhaust gas has a lot, such as absorption absorption, burning method, chemical transformation, condensation method and
Bioanalysis etc., but in these methods, the most cost-effective is biological odor removal method, and biological odor removal method is a kind of odorless, nothing
The process of evilization, i.e., using hydrogen sulfide, reduced sulphur compound in the microorganism species conversion waste gas with deodorization functions etc.
Odorous substance, high with clearance, running expense is low, and operational administrative is simple, the advantages of do not produce secondary pollution, but, it is biological
Deodorization process deodorizing effect relies on the activity of deodorizing microorganism, and deodorant intake air temperature is too high or too low all to influence the growth of microorganism
Breeding, and then deodorizing effect is reduced, when deodorant intake air temperature is higher than 40 DEG C or less than 15 DEG C, deodorizing microorganism growth and breeding is received
To suppression；When deodorant intake air temperature is higher than 60 DEG C, deodorizing effect is lost in deodorizing microorganism mortality.
