Description
Technical field
The invention belongs to waste emulsified mixture processing technology fields, are related to a kind of by ozone high grade oxidation processing waste emulsified mixture steaming
The method of organic matter in lotion.
Background technique
With the continuous development of China's industry, emulsion has been widely used in machining, car engine machining, has rolled
In the cooling and lubrication of Kun and steel plate.As emulsion uses the growth of time, the factors meeting such as hot and cold alternation and microbial degradation
Gradually cause emulsion rotten, lose its original characteristic and effectiveness, it is therefore desirable to periodically replace emulsion, and can be continuous
Generate waste emulsified mixture.Since waste emulsified mixture is toxic, harmful, there is irritation and corrosivity, belong to hazardous waste, thus needs pair
Waste emulsified mixture is handled.
The method of processing waste emulsified mixture mainly includes biofilm, absorption method, embrane method and evaporation etc. at present.In these sides
In method, evaporation has the advantages such as occupied area is small, is widely used in waste emulsified mixture processing.After evaporation process
The concentrate of generation belongs to hazardous waste, need to generally entrust qualified unit as hazardous waste processing, and volume is only original
The 10% of waste emulsified mixture can greatly reduce processing cost；And the evaporation liquid generated after evaporation process, volume are former useless emulsification
The 90% of liquid, content of organics are significantly less than former waste emulsified mixture, can reach emission request or reuse by being further processed.
However, also less to the treatment research of waste emulsified mixture evaporation liquid at present.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of useless creams of oxidation processes
Change the method for liquid evaporation liquid.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of method of oxidation processes waste emulsified mixture evaporation liquid, this method are as follows: ozone is passed through to waste emulsified mixture and evaporates liquid
In, ozone Oxidation Treatment is carried out to the organic matter in waste emulsified mixture evaporation liquid.Ozone is a kind of strong oxidizer, oxidability ratio
The common oxidant such as oxygen, chlorine and permanganate is all high.Under ideal reaction condition, ozone can will be most of in aqueous solution
Simple substance and compound oxidation have strong oxidative degradation to the organic matter in water to their highest oxidation state, and there are also strong
Strong sterilization, it is without secondary pollution, and prepare ozone convenient operation and management.Therefore, the application selects ozone as oxygen
Agent.
Further, the ozone is to be made using oxygen as oxygen source using ozone generator.Ozone generator is to be used for
Produce the device of ozone gas.It can not be stored since ozone is easily decomposes, thus need to be by existing after ozone generator formed in-situ
Field uses.
Further, the ozone is passed through into waste emulsified mixture evaporation liquid by the way of microbubble.Diameter is less than 50 μ
The bubble of m is known as microbubble.Ozone is passed through by the way of microbubble, when can be improved solvability, the ozone stop of ozone
Between, mass tranfer coefficient, and more hydroxyl radical free radicals are generated, to promote the oxidation efficiency of ozone.
Further, this method specifically: using oxygen as oxygen source, generate ozone using ozone generator, and pass through adjusting
Current control ozone concentration detects halitosis oxygen concentration using ozone concentration instrument, and ozone is passed through titanium core aeration head with micro- later
The mode of bubble is passed through in the evaporation liquid of the waste emulsified mixture in reactor, carries out ozone oxidation reaction.
Further, the micropore size of the titanium core aeration head is 0.4-0.5 μm.Excessive micropore size can make ozone
Oxidation efficiency reduces, and too small micropore size, which is passed through, needs bigger pressure in waste water, the maximum allowed more than ozone generator
Pressure, so selecting micropore size is 0.4-0.5 μm of titanium core aeration head.
Further, ozone is passed through before evaporating liquid to waste emulsified mixture, waste emulsified mixture evaporation liquid is first adjusted to alkalinity.
Further, the pH value of waste emulsified mixture evaporation liquid is 10-12.
Further, in waste emulsified mixture evaporation liquid, COD concentration is 1500-2500mg/L, and TOC concentration is 400-
800mg/L, NH3- N concentration is 100-200mg/L.
Further, the temperature of the ozone Oxidation Treatment is 40-50 DEG C, time 1-3h.Increasing temperature can promote
Into the reactivity of Organic substance in water, promotion ozone is reacted with organic matter, but at high temperature, and the dissolution rate of ozone declines, because
And the treatment temperature of 45 DEG C or so of selection, it can utmostly play the oxidation of ozone.
Further, the concentration of the ozone is 80-120mg/L, aeration rate 0.3-0.7L/min.
Ozonation of the present invention mainly includes that ozone directly reacts oxygenolysis organic matter and ozone decomposition
Generate two kinds of approach of indirect oxidation decomposing organic matter again after hydroxyl radical free radical.Ozone direct oxidation reaction speed is relatively slow and has selection
Property, usually attack have double bond organic matter, can be used to remove double bond containing pollutant in waste liquid；Ozone decomposition is produced from
Stronger by the oxidability after base, reaction speed is fast and non-selectivity, and to structure is complicated, organic matter difficult to degrade has good mine
Change effect, thus the scope of application is wider.
Wherein, in acid condition, the degradation of Pre-Ozonation on Organic Matter is predominantly directly reacted；It and is then straight under alkaline condition
It is reversed should be with the synergistic effect of indirect reaction.Therefore, waste emulsified mixture evaporation liquid is adjusted to alkalinity by the present invention, to improve oxidation effect
Fruit carries out efficiently quickly processing to hardly degraded organic substance.
Compared with prior art, the present invention pre-processes waste emulsified mixture evaporation liquid using ozone high grade oxidation technology,
Its organic concentration is reduced, the biodegradability of waste liquid is improved, liquid is evaporated for waste emulsified mixture and handles the row of being finally reached through subsequent biochemical
It puts or reuse requirement provides safeguard.
