以尼日尔Y3菌丝球为生物质载体，对苯胺降解菌醋酸钙不动杆菌JH-9和COD快速降解菌的混合培养物进行了接种试验。将组合菌丝球应用于SBR反应器中，考察其对苯胺和COD的去除效果。并与单独接种JH-9的SBR进行了性能比较。结果表明，两种反应器对苯胺和COD均有稳定的降解效果。在复合菌球SBR中，苯胺的生物去除率为0.9mg/（L.d）。比活性污泥反应器中的高得多。同时，SBR反应器的沉降速度、液固分离性能和出水水质均较好。SEM图像和PCR-DGGE分析表明，生物质载体上的固定化物种在该系统中占优势。(C)2010爱思唯尔有限公司版权所有。
Mycelial pellet of Aspergillus niger Y3 was used as a biomass carrier to immobilize the aniline-degrading bacterium, Acinetobacter calcoaceticus JH-9 and the mix culture of the COD rapid degradation bacteria. In order to investigate its removal effect on aniline and COD, the combined mycelial pellets were applied in the SBR. Comparison of the performances was conducted between another SBR inoculated with sole strain JH-9 and the above SBR. The results showed that the stable degradations of aniline and COD were observed in both reactors. In the SBR with combined mycelial pellet, the biological removal efficiency was about 0.9 mg aniline/(L.d). It was much higher than that in the activated sludge reactor. Meanwhile, the performances of the sedimentation velocity, liquid-solid phase separation and the effluent quality were better in the SBR. According to SEM images and PCR-DGGE analysis, the species immobilized on the biomass carrier were more predominant in this system. (C) 2010 Elsevier Ltd. All rights reserved.
