Abstract

To improve the phenol removal rate for the purpose of changing reaction conditions,this paper studies the effects of potassium ferrate on the removal of simulated phenol wastewater for 1 min,the completion of the oxidation reaction,and the change of pH value in the final filtrate after flocculation reaction. The mechanism of the process is analyzed by the change in pH value. The results show that: Oxidation -flocculation ( adsorption) of potassium ferrate to remove phenol from simulated wastewater,after rapid reaction for 1 min,the pH of the final filtrate is the highest at the optimum temperature. After the flocculation reaction,the pH value of the filtrate will increase first and then decrease with the dosage of potassium ferrate,and the pH value of the final filtrate is fixed in the alkaline range of 7.22 ~ 12.05 with the change in the pH value of the raw water inside. The results show that more acid is produced under better oxidation conditions,and the pH value tends to decrease,and Fe( OH) 3 is produced under better flocculation conditions to increase the pH value of the final filtrate trend,but the final filtrate pH will be fixed in the weak alkaline range. This study provides a theoretical guidance for the change in pH of potassium ferrate to remove phenol.
