- Abstract
The use of ultrasonic，H2O2and the combination of two kinds of technology approach to ultrasound H2O2 phenol wastewater, treatment effect of three methods were compared the differences, and discussed the ultrasonic power, the solution pH value, ultrasonic time and ferrous ions (Fe2 + ) the amount of the treatment effect. The results show that hydrogen peroxide and ultrasonic treatment efficiency of wastewater treatment is superior to ultrasonic treatment group and H2O2 treatment. Through orthogonal experiments of phenol degradation rate of the size of the order has to pH>ultrasonic power>ultrasonic time>adding 0.1mmol·L-1FeSO4 amount of the basis of the experimental parameters, in order to obtain high degradation rate and cost, various factors. Optimization of process parameters for the ultrasonic time of 60 min, power is 200 W, pH is 3, adding FeSO4 amount of 1.0 mL. Under optimum conditions in this experiment, the degradation of phenol was 81.50%. Ultrasonic is relatively separate and separate hydrogen peroxide, the use of ultrasonic hydrogen peroxide degradation rate of phenol, save time, the advantages of speed degradation.
