Study on the Alage Removal by Microwave Irradiation

摘要：

The microwave irradiation (MI) was found that it had significantly treatment efficiency for pollutants removal.It was developed to treat the alage in this paper.The granular activated carbon (GAC) was used as catalyst.The effect of the acting time,MI power,GAC amount and the initial concentration on alage removal were studied.The results showed: with the increasing of the acting time,MI power,GAC amount the alage removal rate were increased,but the effect of the initial concentration to alage removal was opposite;the optimum value of acting time,MI power and GAC amount were 5min,450W and 3g respectively with the alage removal efficiency reached up to 100％.It also showed that with the alage removed under the MI the COD,SS were removed too.It was discovered that the oxidation process was basically in conformity with the first-order dynamic reaction(ln(C/C0)=-0.9371t+0.6744 (R2=0.9472) ).
