摘要: 通过监测固定化曝气生物滤池(immobilized biological areated filter, IBAF)进、出水中不同结构PAHs浓度的变化，分析盐度对其处理效果的影响。结果表明，IBAF反应系统在盐度0%～5%(w/v)，HRT为8 h，COD容积负荷为0.3～0.8 kg/(m3·d)的条件下，对石油类、COD、TOC的平均降解效率达96.7%，95%和85%，分配在油粒中和溶解于水中的PAHs可在载体过滤、吸附和微生物降解等作用下，不随出水排出系统。盐度为1%～2%(w/v)时，进、出水中PAHs浓度较高，是由于增溶作用使PAHs分配在粒径小于100 μm油粒中和水相中的比例升高。出水中测得含2个苯环PAHs占比较大，这可能是由于在3、4环PAHs加氧开环的微生物降解过程中产生中间产物并通过GC-MS自动测量造成的。

Abstract: The effect of salinity on PAHs treatment is analyzed by inspecting the different structure PAHs concentration in influent/effluent of immobilized biological areated filter (IBAF). When salinity was 0%～5%(w/v), HRT was 8 h, and COD was 0.3～0.8 kg /(m3·d), the IBAF system could hold the PAHs attached to the oil particle and degrade the PAHs by microbes efficiently, with the oil, COD and TOC degradation efficiency of 96.7%, 95% and 85%. As the ratio of PAHs distributed in small oil particle(less than 100 μm) was increased by salinity solubilization, PAHs concentration detected in both influent and effluent was higher, when salinity was 1%～2%(w/v). The ratio of PAHs containing 2 phenyls increased in effluent, which might be the interim substance detected by GC-MS automatically was produced by microbes, when they decomposed the rings of PAHs containing 3～4 phenyls.
