| 摘 要： | 工业废水中全氟辛烷磺酸(PFOS)浓度低,直接应用化学法降解能耗较高。采用膜分离与UV/SO3^2-光降解的组合工艺对其进行处理,研究了此组合技术的处理效果,并考察了影响降解率的因素。结果表明,反渗透膜可有效富集PFOS溶液,高强UV/SO3^2-体系可高效降解该富集溶液。提高溶液初始pH、SO3^2-浓度、紫外光强,均有利于PFOS降解率的提高,而PFOS初始浓度的提高会降低其降解率。

| Abstract: | When the chemical degradation method was directly used to treat PFOS with a low concentration in the industrial wastewater,it resulted in the drawback of high energy consumption.For this consideration,the membrane separation technology was combined with UV/sulfite system for PFOS treatment.The processing effect of this combination technology was studied,and relevant influence factors on PFOS degradation efficiency were investigated.The results showed that high PFOS enrichment could be achieved by using reverse osmosis membrane.Meanwhile,the concentrated solution was efficiently degraded in a high-intensity UV/sulfite system.In addition,the PFOS degradation efficiency was increased by increasing the initial solution pH,sulfite dosage and UV intensity,respectively,whereas its degradation efficiency was decreased by increasing the initial PFOS concentration. |
