The use of ultrasonic，H2O2and the combination of two kinds of technology approach to ultrasound H2O2 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 (Fe2 + ) 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 H2O2 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-1FeSO4 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.
