摘　　要：为了摸索适合油页岩干馏废水水质特点的处理工艺,提出了"混凝沉淀-溶气气浮-A/O-MBR-纳滤"的处理工艺流程,并进行相关试验研究。在系统稳定运行后,经过优化调整工艺参数,CODCr、BOD5、NH3-N、石油类的去除率分别达到97.7%、98.2%、99.2%、99.3%,不计人工费的吨水处理运行费用约为7.6元,出水水质符合GB 8978—1996《污水综合排放标准》中石油炼化行业二级排放标准的要求,运行成本经济可行,说明该工艺处理油页岩干馏废水是切实可行的。In order to seek out a proper process for oil shale retort wastewater treatment, coagulation sendi- mentation-dissolved air flotation-A/O-MBR-nanofihration combined process was proposed, and the relevant ex- periment was studied. When the system running stable, through the modification of parameters, the removal rates of CODc~, BODs, NH3-N and petroleum reached 97.7%, 98.2%, 99.2% and 99.3% respectively, the cost for 1 ton wastewater treatment was about 7.6 yuan irrespective of labor cost, the effluent water quality met the specification for grade II in GB 8978--1996 Integrated wastewater discharge standard for petroleum refining industry and the operation of the system was economic and practical, which showed that, using the said combined process to treat oil shale retort wastewater was feasible.
