Description

A kind of vegetative microorganism liquid for deodorizing and production method

Technical field

The invention belongs to gas purification technique field, particularly relate to a kind of vegetative microorganism liquid for deodorizing and production method.

Background technology

In recent years, along with the development of microbial fermentation technology, organic waste anaerobic fermentation becomes rapidly a new industry, huge economic benefit is brought to enterprise, but the front and back of process discarded object can produce the poisonous gas of a large amount of foul smelling smell, as hydrogen sulfide, ammonia, methane, thio-alcohol, dimethyl disulfide, Trimethylamine, styrene and phenols etc.These gases not only have an impact to the sense of smell of people and cause the offending sensations such as psychology detest, also all can cause murder by poisoning in various degree to human body respiration, digestion, cardiovascular, endocrine and nervous system, partial aromatic compounds of group even can make human body produce distortion, canceration, to the person causing very large harm, common symptom has the symptoms such as nauseating, headache, poor appetite, sense of smell imbalance, insomnia.Therefore, odor pollution problem causes extensive concern both domestic and external.

Current Odor control mainly adopts chemical washing method, active carbon adsorption, the technology such as bioanalysis.Chemical washing method is contacted with liquid flux (as water, acid, alkali etc.) by foul gas, make pollutant transfer to liquid phase from gas phase, the method has higher treatment effeciency to water miscible gas, but it is large to there is reagent consumption amount, operating cost is high, the shortcoming that secondary pollution is serious.The chemical characteristic (except functional group's effect) of active carbon adsorption foundation porosu solid adsorbent and physical characteristic (microvoid content, specific area, microporous structure), odorant is gathered or condensing its surface, reach the effect of purification; This method has good treatment effect to multiple foul gas, but due to charcoal absorption saturated after need periodic replacement, operating cost is very high.Microbial deodorant deodorization technology is the emerging deodorization technology grown up the 1950's, is the physiological metabolism activity degraded odorant utilizing microorganism, is oxidized to odorless, harmless end product, reaches the object of deodorizing.Bioanalysis with its safety, efficient, energy-saving and environmental protection, non-secondary pollution and win the favor of people, and obtains and develops rapidly.But the effect of biological deodorizing is the activity of microorganism, and the efficient key that maintains of microbial activity is that the component proportion of the nutrient solution needed for microbial activities metabolism controls with operation.Given this, the present inventor, according to the physiological property of microorganism, through operative practice more than a year, develops a kind of vegetative microorganism liquid for deodorizing and production method, considerably increase the concentration of unit volume microorganism, for high load capacity, multisystem process foul smell provide possibility.

Through retrieval, patent CN 103951486 A discloses a kind of plant nutrient regulates liquid fertilizer and production method thereof, this report is also utilize natural pond liquid, beneficial microbe bacterial classification, the fermentation such as sugar is made, but the beneficial microbe bacterial classification in this report uses as leavening, its effect is after fertilising, these beneficial microbe bacterial classifications decompose the material in soil by metabolism, produce a large amount of nutrients, meet demand of plant growth, but owing to lacking necessary functional beneficial microbe bacterial classification, not there is deodorization functions, and this formula is only bacterial classification life and provides necessary nutrient, do not take the measure of any accelerate growth of microorganism, make sweat relatively long.In addition, in the liquid of natural pond, may microorganism fungus kind be there is, if unsterilised and directly apply, very likely cause because of vying each other beneficial microbe bacterial activity to decline, causing deodorizing effect poor.
