| 摘 要： | 通过固定化手段,将筛选出来的优势菌种应用于生物活性炭挂膜过程,形成固定化生物活性炭(IBAC),加速挂膜过程,并用于微污染水的处理。研究结果表明,自然挂膜需要24 d,而采用固定化微生物9 d挂膜完成,对氨氮去除率达到90%,微生物挂膜时间缩短了60%。IBAC表面的微生物数量高于自然挂膜BAC微生物量,并且沿着水流方向微生物量逐渐减少。微生物镜检发现,运行3个月的IBAC表面出现大量菌胶团、轮虫和钟虫等原生和后生动物。IBAC具有较快的启动挂膜性能和较好的微污染水处理效果。

| Abstract: | Predominant species were selected and attached to the activated carbon surface by immobilization method to form immobilized biological activated carbon(IBAC). Therefore, the biofilm formation period on the activated carbon can be accelerated. IBAC process was also used to treat the micro-polluted water. The results show that, compared with the natural biofilm formation period of 24 days, the biofilm formation period of IBAC was reduced 60% to 9 days. The removal of ammonia by IBAC was 90%. Microbe quantity of IBAC was higher than that of the natural BAC. What's more, microbe quantity of IBAC gradually decreased along the water flow direction. The microscopical study found that lots of protozoa and metazoa, including zoogloea, rotifera, and vorticella, appeared on the surface of IBAC. With the rapid biofilm formation period, IBAC can effectively treat micro-polluted water. |
