| Abstract: | The method of modification was determined by investigating the leaching rate of Fe2O3 and Al2O3 of fly ash and comparing the removal effect of phenol in waste water.During the study of the removal ratio in waste water treatment the dosage of fly ash,stirring time and static time were investigated.The best result was reached at the following condition:the dosage of fly ash was 10g/L,the stirring time was 45 min,and the static time was 55 min. |
