固定化微生物技术在废水处理中的应用

固定化微生物技术是一种高效的废水生物处理技术，具有能保持高效菌种，稳定性强，反应易于控制，污泥产生量少，能够去除高浓度有机物及难降解物质等优点。对载体的选择及常用的固定化方法进行了介绍，分析了各种方法与载体在应用中的优缺点。重点叙述了固定化微生物技术在含难降解有机物废水、含重金属离子废水、含高浓度有机废水、含氮含磷废水中的应用现状。但要实现其工业化，仍然有诸多问题需要解决，主要包括：固定化参数的建立、载体的选择、运行成本的削减等。

The Application of Immobilized Microorganism Technology in Wastewater Treatment

Immobilized microorganism technology is one technique of the effective biotechnology for wastewater treatment. It has the advantages of the seed culture of bacteria with high activity and stability, the reaction easily controlled, low amount of sludge produced and removal the organic matter and substances difficultly degraded. The selection of carriers and immobilized technology they used is introduced, then the merits and faults of methods and carriers are analysed in application. It reviews the recent application of immobilized microorganism technology in difficult degrades wastewater, toxicity heavy metals wastewater, organism wastewater, N and P wastewater. However, to achieve its industrialization, there are still many problems to be solved, ineluding the estabilishment of immobilized parameters, the choice of carriers, the reduction of operating costs as well.
