Abstract:
In order to determine the sintering temperature of Cu-AC that was prepared by impregnation,and find out the treatment effect of catalytic oxidation process,Cu(NO3)2/AC of Cu/AC predecessor has been analyzed by TGinfrared spectroscopy online analytical processing.It is determined that the optimum sintering temperature of Cu-AC is 700 ℃.Cu-AC is used as catalyst,and H2O2 as oxidant.Under the following conditions:m(H2O2)∶m(COD)= 1.4,and m(Cu -AC) ∶m(H2O2) =1.5,the mid low temperature coal tar phenol extracting wastewater is treated by catalytic wet peroxide oxidation process.Its COD removing rate reaches 91.8%, having achieved good results.

摘要:
为了确定通过浸渍法制备的载铜活性炭的焙烧温度,并了解其催化氧化的处理效果,利用热重-红外光谱联机分析方法对载铜活性炭(Cu-AC)前驱物Cu(NO3)2/AC进行分析,确定Cu-AC的最佳焙烧温度为700℃。并以自制的Cu-AC为催化剂,H2O2为氧化剂,在m(H2O2)∶m(COD)=1.4,m(Cu-AC)∶m(H2O2)=1.5条件下,对中低温煤焦油提酚废水进行催化湿式过氧化法处理,COD去除率达到91.8%,取得了良好效果。
