摘　　要：采用中空纤维膜生物反应器(HFMBR)去除气态复合苯系物。挂膜后期,生物反应器的去除效率可以稳定达到80%左右(去除能力(EC)≥225 g/(m3.h))。研究了中空纤维膜生物反应器处理对于单一二甲苯以及混合二甲苯的性能,并且发现HFMBR对于去除单一二甲苯和混合二甲苯都有明显的效果,去除效率均达到90%以上;表明二甲苯之间竞争效应带来的相互抑制作用小。在低浓度的情况下,单一二甲苯和混合二甲苯的去除能力呈线性增加,在高浓度阶段,去除能力增加变缓。比较了混合二甲苯与甲苯联合降解,发现两者之间存在相互抑制作用,但相比传统生物反应器有明显的改善。与传统生物过滤系统比较而言,膜生物反应器有着很好的应用前景。The hollow fiber membrane bioreactor （HFMBR） was used to remove gaseous mixtures of ben- zene series. During biofilm colonization, the removal efficiency and elimination capacity （EC） of bioreactor reached around 80% , 225 g/（ m3 · h） , respectively. The performance of the HFMBR for treating single and mixed xylene were investigated, and it was found that the HFMBR can effectively treat both single and mixed xy- lenes, and the removal efficiency was over 90% , which indicated that the inhibition effect between xylene spe- cies was weak. The removal capacity of single and mixed xylenes increased linearly when the inlet concentration was lower while the increase became slower at higher concentration. Through comparing degradation of mixed xy- lene with toluene, the inhibition effect between them was found. However, the inhabitation was still lower than the conventional bioreactor. The membrane bioreactor therefore has a promising prospect for application com- pared with conventional biofihration process.
