Abstract
This paper analyzes the use of ozone in treating waste water containing phenol organics based on experiment and theoretical research. It adopts experiments to learn the degradation effect of ozone on industrial waste water treatment under different conditions of ozone input amount, concentration level of phenol substance in solution, pH value, and reaction time, then compares the experiment results against the theoretical calculated results. When the initial concentration is 100 mg/L, ozone has good degradation effect on the phenol waste water. Degradation rate of ozone lowers as the concentration increases. The degradation rate also increases as the amount of ozone input increases. When pH value gradually raises, the degradation rate of waste water also improves, indicating that ozone has better degradation effect in an alkaline environment. The longer the reaction time is, the lower the phenol organic concentration in the waste water is. kA value is in direct proportion to the pH value, and in reverse proportion to the phenol organic concentration. Based on the comparative results, the optimum value of is kA witnessed at 0.00103.
