摘　　要：采用生物吸附-厌氧-移动生物膜反应器(BA-H-MBBR)组合工艺进行炼油废水处理实验研究,并平行模拟原有工艺厌氧-好氧-好氧(A-O-O)工艺进行对比实验,同时利用紫外-可见吸收光谱和顶空-固相微萃取(HS-SPME)-气质联用仪(GC/MS)对现有A-O-O工艺和新开发的BA-H-MBBR工艺的处理效果进行评价。紫外-可见吸收光谱监测结果显示,BAH-MBBR工艺出水水质优于A-O-O工艺,且具有更好的单环芳烃族化合物(苯酚、苯胺等)去除能力;GC/MC在进水中共检出60种有机污染物,在A-O-O工艺出水(O_2)、BA-H-MBBR工艺出水(M2)中只分别检出14种和6种有机物,表明进水经过生化工艺处理后,大多数有机污染物均得到降解和去除;M2中检出的有机物种类较O2中的低得多,并且M_2和O_2分别检出2种、7种含氮有机物,显示出BA-H-MBBR工艺更优异的有机物处理能力,并且在处理含氮有机物方面具明显优势。A combined process BA-H-MBBR is employed to treat the oil refinery wastewater,by using the old A-OO process as the parallel experiment. UV-visible absorption spectroscopy and HS-SPME-GC / MS are used to make an indepth assessment of these two processes. The results show that the effluent quality and the monocyclic aromatic compound（ phenol,aniline,etc.） removal capacity of BA-H-MBBR process are better than that of A-O-O process. 60 compounds in total can be identified by GC-MS from the inlet wastewater. In contrast,in the effluent from A-O-O process and BA-HMBB,only 14 and 6 compounds are identified,respectively,indicating the removal of most of the compounds from the inlet wastewater by biological treatment. The species and content of organic substances in BA-H-MBB is much lower than that in A-O-O process. Only 2 nitrogen-containing compounds are found in the BA-H-MBB treated water. BA-H-MBB exhibits a better ability of to handle organic matters,especially nitrogen-containing compounds.
