生物滴滤池处理废气中生物质的积累与控制措施

Waste Air Treatment in a Biotrickling Filter: Biomass Accumulation and Control Measures

生物滴滤池在废气处理中具有其无以比拟的优点,但由于其在工业化应用面临的最大难题就是如何解决生物质积累所带来的种种问题。综述分析生物滴滤池处理废气中生物质的积累的危害;以εf和αf为参数探求其积累的机理;生物质积累的控制措施,包括化学法、物理机械法与其他一些方法。

Biotrickling filter often offers a cost effective and environmentally friendly alternative to conventional air pollutant control technologies, but major problems with clogging of the filters due to a high biomass accumulao tion will provent it from the industried uses. In this paper, the effect of the high biomass accumulation in an air pollution treatment with a biotrickling filter is discussed. Two parameters with specific surface area with biofilm growth （αf） and the bed porosity with biofilm （εf） are used to analyse its principle of accumulation. Finally, some control measures including chemical methods, physical machine-made methods and other control methods are overviewed.
