摘要:
制备了二氧化钛/氧化石墨烯（TiO2/GO）和磁性二氧化钛/氧化石墨烯（磁性TiO2/GO）两种复合催化剂，并用其处理垃圾渗滤液。考察了复合催化剂中TiO2与GO的质量比、催化剂投加量、反应时间对COD去除率的影响，并采用SEM、XRD、VSM、FTIR等手段对复合催化剂进行表征。结果表明，磁性TiO2/GO复合催化剂表面粗糙、纯度高、磁回收性能良好。当TiO2与GO的质量比为5∶1、催化剂投加质量与垃圾渗滤液COD的质量比为0.8、反应时间为3 h时，对COD的去除率最高，可达65.35%，此时垃圾渗滤液出水COD为1 774 mg/L，可生化性（BOD5/COD）由0.20提高至0.45。
Abstract:
Titanium dioxide/graphene oxide (TiO2/GO) and magnetic titanium dioxide/graphene oxide (magnetic TiO2/GO) composite catalysts were prepared and applied to treat landfill leachate. The effects of mass ratio of TiO2 to GO, catalyst dosage and reaction time on COD removal efficiency of the composite catalyst were investigated, and the composite catalyst was characterized by SEM, XRD, VSM and FTIR. The magnetic TiO2/GO composite catalyst had a rough surface, high purity and good magnetic recovery performance. The removal efficiency of COD reached the maximum of 65.35% under the following conditions: the mass ratio of TiO2 to GO was 5∶1, the mass ratio of catalyst dosage to COD in landfill leachate was 0.8 and the reaction time was 3 h. At this time, COD in the effluent was 1 774 mg/L, and the biodegradability (BOD5/COD) was increased from 0.20 to 0.45.
