生物膜填料塔对低浓度甲苯废气的净化性能研究

Study on the Performance of Biofilter for Purifying Low Concentration Toluene Waste Gas

在扩大的实验装置上，考察研究了入口气体甲苯浓度、气体流量、液体喷淋量、填料层高度、操作方式等因素对生物膜填料塔净化低浓度甲苯废气性能的影响，取得了一定的基础数据，为下一步的工业应用提供依据。

An enlarged biological trickling filter with biofilm packing was used to purify low concentra-tion toluene waste gases and the main affecting factors, such as the concentration of toluene in in-let gas, gas flow, liquid flow, height of biofilm packing and operating method, were investigatedrespectively. The results are very useful for the application of the biochemical method to treat thelow concentration industrial waste gases.
