Ultrasonic Technology Of Phenol And Ethanol Wastewater

Water pollution is one of the most urgent problems, which has to be soluted, specially the treatment of the difficult degradable organic pollutants ,which is the important topic of protectical environment research. As a kind of new interdisciplinary edge studies, the phonochemical technology has remarkably showed its good applicable prospect on wastewater treatment, particularly in dealing with the difficult treated that the organic pollutant which is poisonous.This article introduces the application principle and mechanism of ultrasonic in wastewater treatment process. It takes phenol and ethyl alcohol that are two kinds of common organic wastewater which as the main wastewater constituent of the simulative wastewater. The intermittent ultrasonic generator was used to treat the simulative wastewater. By the experiment we find that:(1) The initial pH value of reactant,initial concentration of reactant,ultrasonic reaction time,ultrasonic power,air current capacity will be affected to the chemical oxygen removal rate. The rule is that increasing the ultrasonic time would be advantageous to the degradation of wastewater organic; lowering concentration of the treated organic sample by ultrasonic process is more effective than the higher one; The different organic waste water have their own supreme ultrasonic power; the higher of the current capacity is that the more advantageous is the ultrasonic degradation; while it is favor to the ultrasonic degradation with the smaller broken quantity of wastewater sample; the different organic is corresponding a better initial pH value.(2) The dynamic reaction of phenol and ethyl alcohol to be ultrasonic treatment process correspond the first order, the dynamic equation are: CA=6.3853exp(-0.0008t), and C_A=12.87exp(-0.0042t).(3) When we increase the Fenton reagent and use the different supersonic equipment, the chemical oxygen demanded COD has a more remarkable fluence, which explaine the union processing technology can effectively enhance the supersonic degeneration effect, the continual soundam plitude pole plunges the type phonochemistry reactor degrade the effect to be better. The result of experiment indicated when degrade the sole ultrasonic technology phenol and ethyl alcohol, the overall COD removed rate is not high, but the ultrasonic technology union can effectively enhance COD removed rate; This research not only deeply understands the mechanism of ultrasonic degradation, but also provides certain valuable parameter for practical application; and lays the foundation for further research on ultrasonic degradation of organic wastewater.
