摘　　要：重庆市某垃圾焚烧厂渗滤液采用UASB/好氧/超滤(UF)/碟管式反渗透(DTRO)处理工艺,采用高效液相色谱串联质谱测定各处理单元进出水中的全氟辛酸(PFOA)浓度,探究不同季节下各处理单元对PFOA的去除效果,并采用一元回归法分析温度、p H值、DO浓度、UF膜口压力及DTRO运行压力等因素与PFOA去除率的相关性。结果表明,不同季节对UASB和好氧池单元去除PFOA的影响显著,而对UF、DTRO处理单元的影响不大;pH值、温度及好氧池DO浓度与PFOA去除率呈显著的负相关性,而UF膜口压力、DTRO运行压力与PFOA去除率呈显著的正相关性;DTRO处理单元是去除渗滤液中PFOA的主要途径。The leachate from a waste incineration plant in Chongqing was treated by UASB/aerobic/ultrafiltration(UF)/disc tube reverse osmosis(DTRO)process.The perfluorooctanoic acid(PFOA)concentrations in the influent and effluent of each treatment unit were analyzed by high performance liquid chromatography/mass spectrometry.The removal effect of PFOA by each treatment unit in different seasons was explored,and the correlation between PFOA removal rate and factors such as temperature,pH value,DO concentration,UF pressure and DTRO operating pressure was analyzed with the unitary regression method.The effects of different seasons on the removal rate of PFOA in UASB and aerobic units were significant,but those in UF and DTRO units were not.There were significant negative correlations between pH value,temperature and DO concentration of aerobic unit and PFOA removal rate,while there were significant positive correlations between UF pressure,DTRO operating pressure and PFOA removal rate.The removal of PFOA from leachate was mainly ascribed to DTRO unit.
