Description

Biofilter odor treating device and method
Technical field
The present invention relates to odor treatment device technical field, a kind of rational in infrastructure, working stability, process effect Biofilter odor treating device that rate is high and method.
Background technology
Foul smell makes people's spirit dysphoria, absent-minded, and work efficiency reduces, it is judged that unable to do what one wishes, hypomnesis, Affect the thinking activities of brain.Stench is serious, to respiratory system, blood circulation, digestive system, endocrine system to the harm of human body System and nervous system etc. adversely affect.Rising after blood pressure being made to occur falling before such as pungent odors such as ammonia, pulse are first The phenomenon accelerated after slowing down.Often in contact with stench, people's anorexia can be made, feel sick, even vomit, and then develop into digestive function and subtract Move back.Stimulated by a kind of several low concentration odorants for a long time, the obstacle such as anosmia, olfactory fatigue can be caused.Stench makes Cranial nerve is constantly upset and damages.
Process foul smell technology and have the operation experience of decades, along with raising and the environmental protection of domestic economy level The reinforcement of consciousness, is the most just starting to rise and in moving towards flourishing trend.At present, main process foul smell technology Active carbon adsorption, thermal oxidation method, oxonium ion group process foul smell method, chemical washing method, Biological fitler method etc., wherein adsorb Desorption processes: activated carbon is the most traditional material processing organic exhaust gas, and it has good absorption and makees part VOCs With, and can be with desorption and regeneration.But it is high that subject matter is operating cost, and after-treatment bothers.For fish meal factory, it is not appropriate for Use this method.Reason is: molecular weight is less than 45 and the high material volatilized stably should not be adsorbed by activated carbon, substantially due to fish Powder factory waste gas is not suitable for, with the material of activated carbon adsorption, using activated carbon adsorption to be difficult to up to standard containing ammonia, hydrogen sulfide, amine etc.. Organic gas in catalysis combustion catalysis burning decomposable asymmetric choice net waste gas, is degraded into carbon dioxide and water.But it is big that subject matter is energy consumption, The treatment operating costs generally burned is more than 6 times of activated carbon operating cost, is the 15 ~ 20 of biological treatment foul smell method Times.Odorant pollutant in waste gas, by oxides such as chlorine, chlorine dioxide, ozone, is aoxidized and degrades by chemical oxidation.Main Wanting the problem to be: (1) consumes a large amount of chemical agent, operating cost is high;(2) strong oxidizer, corrosive equipment, equipment investment are used Costly.Biological fitler method biofiltration technique have employed liquid and absorbs and the compound action of biological treatment.First foul smell is filled out Material absorption and sorption, foul smell is absorbed by microorganism as nutrient substance, metabolism and utilization, is degraded into by odor pollution thing simultaneously Water and carbon dioxide.Biofiltration processes foul smell technique, has non-secondary pollution, and operating cost is low, it is simple to the advantages such as maintenance.
