    摘要:

    本文采用共沉淀法,以钛硅分子筛(HTS-1)作载体,制备Cu-Mn-Ce/HTS-1负载型催化剂。构建臭氧- Cu-Mn-Ce/HTS-1催化臭氧化降解体系,考察对象为布洛芬模拟废水,在不同催化性能条件下用Cu-Mn-Ce/HTS-1对布洛芬废水进行处理以探究不同条件对处理效果的影响,并对催化剂进行XRD、TEM和BET表征。实验结果显示:在反应初始溶液pH=7、臭氧投加量为30mg/min、Cu-Mn-Ce负载量为20%及催化剂投加量为0.75g的条件下,布洛芬废水中TOC的去除率最高可达95.4%。Cu-Mn-Ce/HTS-1催化剂重复利用实验表明经使用3次后,废水中TOC的去除率仍然能达到79.1%,表明该催化剂的稳定性和较重复利用性都较好。

    Abstract:

    In this paper, Titanium Silicalite-1 (HTS-1) was used as a carrier to make the Cu-Mn-Ce/HTS-1 supported catalyst by coprecipitation method. Cu-Mn-Ce/HTS-1 supported catalyst was prepared. The ozone-Cu-Mn-Ce/HTS-1 catalytic ozonation degradation system was constructed and the ibuprofen wastewater was treated with Cu-Mn-Ce/HTS-1 under different catalytic performance conditions to explore the influence of different conditions on the treatment effect. The catalysts were characterized by XRD, TEM and BET. The experimental result shows that the removal rate of TOC in ibuprofen wastewater can reach 95.4% under the conditions of initial solution pH=7, ozone dosage of 30mg/min, loading of 20% Cu-Mn-Ce and catalyst dosage of 0.75g. The reuse experiment of Cu-Mn-Ce/HTS-1 catalyst shows that the removal rate of TOC in wastewater can still reach 79.1% after three times of use, which indicates that the catalyst has good stability and reusability.
