摘　　要：实验采用直接UV光降解叔丁基过氧化氢(TBHP)废水,研究了TBHP的降解性能,分析了TBHP初始浓度、温度、pH值和无机离子共存对TBHP降解效率的影响。结果表明,当TBHP浓度为1.75g·L^(-1)、pH值为3时,TBHP的UV光降解遵循准一级动力学模型,表观降解速率常数达到0.217min^(-1),同时利用GC-MS分析了UV光降解TBHP的产物和路径。此外,实验研究了TBHP废水与其他工业废水混和后直接UV光降解的过程,结果表明,混合废水有机物降解效果优于单一废水,也为TBHP废水的资源化利用提供了新的途径。This study employed direct UV photodegradation to investigate the degradation performance of tert-butyl hydroperoxide(TBHP)wastewater.The influence of initial TBHP concentration,temperature,pH value,and coexistence of inorganic ions on TBHP degradation efficiency was analyzed.The results demonstrated that under conditions of TBHP concentration at 1.75g·L^(-1) and pH at 3,UV photodegradation of TBHP followed a pseudo-first-order kinetic model.The apparent degradation rate constant reached 0.217min-1.Additionally,the products and pathways of UV photodegraded TBHP were analyzed using GC-MS.Furthermore,the study explored the direct UV photodegradation process of mixed TBHP wastewater with other industrial wastewaters.The outcomes indicated that the degradation efficiency of organic compounds in mixed wastewater was superior to that of individual wastewater.This approach also presents a novel avenue for the resourceful utilization of TBHP wastewater.
