Abstract
A process for treating industrial sewage by cooperation of aerating and ultrasonic waves features that the industrial sewage containing volatile or hydrophobicity substance is aerated by the ratio of air to water of (100-1000):1 while acted by ultrasonic waves (10 KHz-1MHz and 0.2-10W/sq.cm) for 5-90 min. Its advantages are high effect and low energy consumption.
Description
One, technical field
The present invention relates to a kind of processing method of industrial waste water, specifically, is to handle trade effluent by the stack synergy of aeration stripping and ultrasonic stripping.
Two, background technology
Aeration stripping is a kind of phase transfer of technology that is widely used in the trade effluent.It flattens weighing apparatus and solution liquid-gas interface character by changing gas-liquid, make some volatile matter in the liquid phase by stripping to liquid phase, pass through retrieving arrangement then, thereby reach purified industrial waste water and make it the purpose of resource utilization.Aeration stripping is mainly used in the CO that removes in the waste water
2, NH
3, H
2S, HCN, CS
2Deng volatile matter.But aeration stripping has significant limitation, because the unicity of its physical action makes clearance can not reach a high level, and powerless to some half volatiles, hydrophobic some toxic organic compound.
Ultrasonic technology makes in recent years by the novel method of the processing difficult degradation poisonous organic wastewater of extensive concern.Present research focus one is a difficult degradation toxic organic compound in the ultrasonic sonochemistry degraded water body; The one, ultrasonic wave and other chemistry or biological method coupling are handled some industrial production waste water or sanitary sewages, for example ultrasonic wave and oxygenant (O
3, H
2O
2) combination process, ultrasonic wave and TiO
2Photochemical catalytic oxidation, ultrasonic wave and micro-electrolysis combined technology, and ultrasonic wave improves the biodegradability of waste water as the preconditioning technique of biological treatment.No matter be single ultrasonic degradation technology, or the combination process of ultrasonic wave and other technologies, still being in the laboratory study stage at present both at home and abroad, its industrialization also is faced with many difficulties.At first, single use ultrasonic degradation treatment of organic matters of organic effect is unsatisfactory, and its wastewater treatment equipment is still waiting to improve; Secondly, ultrasonic and additive method coupling has improved the cost of water treatment, facts have proved, the running cost of combination process is the twice of single ultrasonic degradation technology in the unit time, so be difficult to realize industrialization.Hyperacoustic stripping performance provides wide prospect more for its industrialization in water treatment.It not only can make some volatile inorganics (H
2S, NH
3, HCN) realize that gas-liquid is separated, and some volatility or hydrophobic toxic organic compound (as chlorobenzene, methylene dichloride, acetone etc.) stripping can be gone out liquid phase.But still there is certain limitation in single use ultrasonic wave stripping technology, it is not high that some hydrophilic high density volatility inorganicss are removed efficient, and need high-power electromagnetic conversion ultrasonic technique, improve the ultrasonic sound intensity, to improve the stripping rate by consuming a large amount of electric energy.
Three, summary of the invention
1. goal of the invention: the purpose of this invention is to provide a kind of technology, the stack synergy by aeration stripping and ultrasonic stripping makes and handles the trade effluent efficient low-consume, has bigger universality.
2. technical scheme: technical scheme of the present invention is as follows:
The trade effluent that contains volatility or lyophobic dust that will handle is delivered to producer, trade effluent in the producer is carried out aeration and ultrasonic wave effect simultaneously, the gas-water ratio of its aeration is 100～1000: 1, the frequency of ultrasonic scope is 10KHz～1MHz, and sound intensity scope is 0.2～10W/cm
2, aeration and ultrasonic wave synergistic reaction time are 5～90 minutes.
The trade effluent that contains volatility or lyophobic dust that will handle constantly is delivered to producer, trade effluent in the producer is carried out aeration and ultrasonic wave effect simultaneously, the gas-water ratio of its aeration is 100～1000: 1, the frequency of ultrasonic scope is 10KHz～1MHz, and sound intensity scope is 0.2～10W/cm
2, aeration and ultrasonic wave synergistic reaction time are 5～90 minutes.
Before trade effluent enters producer, need carry out some conventional pre-treatment,, regulate simple physical and chemical processes such as pH value, carry out according to the difference of trade effluent kind as filtering.Ultrasonic can the generation by employing sound horn,amplitude transformer formula electromagnetic transducer also can adopt the pneumatic ultra-sonic generator of high-speed gas to produce.For different trade effluents, because the difference of contained volatility or lyophobic dust, the selection of ultrasonic frequency is relevant with the character and the treatment capacity of the selection of the sound intensity and trade effluent.
For the trade effluent that has corrodibility and toxicity and recovery value is arranged, adopt closed reactor, reclaim liquid and select according to different recover materials.
3. beneficial effect: the present invention compared with prior art, its remarkable advantage is: when the present invention is used to remove some volatility or hydrophobic inorganics or toxic organic compound, can be so that clearance brings up to 90%, overcome the defective of aeration stripping and ultrasonic stripping individual curing, efficient low-consume has bigger universality and is easy to industrialization.
