摘要：为了考察膜生物反应器(membrane bioreactor,MBR)对焦化废水中萘的去除特性,采用小试规模厌氧/缺氧/好氧-膜-生物反应器(A_1/A_2/O-MBR)系统处理实际焦化废水,研究了萘在A_1/A_2/O-MBR处理系统中的存在特性与去除效果。研究结果表:A_1/A_2/O-MBR系统能有效去除焦化废水中的萘,当进水的质量浓度为(265.5±119.0)μg/L时,去除率为(99.4±0.5)%,出水的平均质量浓度为(0.95±0.59)μg/L。生物处理是A_1/A_2/O-MBR系统水相中萘去除的主要途径,膜的截留对萘没有强化去除作用。
To explore the treatment performance of membrane bioreactor for the naphthalene removal in real coke wastewater,a laboratory scale anaerobic anoxic oxic membrane bioreactor(A1/A2/O MBR)system was used to treat real coke wastewater.The occurrence and removal of naphthalene in this system were investigated.The results indicated that A1/A2/O MBR system is efficient in naphthalene reduction.When the average influent naphthalene concentration is(265.5±119.0)μg/L,the removal of(99.4±0.5)%can be achieved with the effluent concentration of(0.95±0.59)μg/L.Biological treatment is crucial to the contribution of naphthalene reduction in the A1/A2/O MBR system,while the membrane rejection can not enhance the removal of naphthalene.
