借助于次级利用促进2,4,6-三氯酚的降解与矿化

摘要

Three protocols,photocatalysis alone (P) ,biodegradation alone (B) ,and intimately coupled photocatalysis and bio-degradation (P&B) , were respectively used for degradation and mineralization of 2,4,6-trichlorophenol ( TCP). TCP could hardly be mineralized, although TCP removal rate could be accelerated by protocol P&B compared that by protocol P and B. When phenol was added,TCP could be obviously mineralized by means of secondary utilization and TCP removal rate could be also accelerated further simultaneously.%分别采用单独光催化氧化(P)、单独生物降解(B)、光催化氧化与生物降解同步耦合(P&B)三种方法对2,4,6-三氯酚( TCP)进行降解,光催化与生物耦合的方法(P&B)虽然能够提高TCP的降解速率,但不能使TCP得到矿化.通过添加苯酚,借助于次级利用除了可以进一步提高TCP的降解速率,还可以提高其矿化程度.
