摘　　要：以陶瓷-活性炭球为载体制备载Ru催化剂,用于催化湿式氧化(CWAO)法处理酚醛树脂废水,考察了陶瓷-活性炭球载体、Ru负载量和陶瓷球宏孔孔径等对催化剂的催化活性和稳定性的影响。实验结果表明,催化剂催化活性的顺序为:Ru/KC-120>Ru/KC-80>Ru/KC-60>KC-120>无催化剂。在200℃,氧气分压为1.5 MPa等条件下,催化湿式氧化酚醛树脂废水,3%Ru/KC-120催化剂表现良好的催化活性与稳定性,在120 min内,COD和苯酚去除率分别达到91%和96%。Ceramic-activated carbon sphere as support of ruthenium catalysts were evaluated through the catalytic wet air oxidation（CWAO） of resin effluent.The effects of the preparation conditions,such as ceramic-activated carbon sphere support,Ru loading,macro-pore diameter of ceramic sphere,etc.on the catalytic activity and stability were investigated.The results show that the catalytic activity varies according to the following order： Ru/KC-120 Ru/KC-80 Ru/KC-60 KC-120 without catalysts.It is found that the 3% Ru/KC-120 catalyst displayed highest stability in the CWAO of resin effluent during 120 min.Chemical oxygen demand（COD） and phenol removal were about 91% and 96%,respectively,at the reaction temperature of 200℃,oxygen pressure of 1.5 MPa.
