摘要
通过动态条件挂膜和静态降解曲线比较对丝网、ＡＣＯＦ、聚乙烯多面小球、炉渣等介质作为气体生物滴滤池生物载体材料的性能进行了研究．实验结果表明，４种材料都可用作生物载体材料，各材料的挂膜量比为：丝网ｖＡＣＯＦｖ多面小球ｖ炉渣＝ ７．１４ｖ９．５２ｖ２．０５ｖ１，半降解时间比大致为：丝网ｖＡＣＯＦｖ多面小球ｖ炉渣＝ ０．４３ｖ０．５ｖ０．７ｖ１，网状结构的丝网和ＡＣＯＦ挂膜量大、降解效果好，比表面积大的多面小球次之，炉渣最差．实验还表明：４种挂膜载体在闲置一段时间后，具一定吸附性能的ＡＣＯＦ的降解性能缓冲、恢复效果最佳。
Experiments were conducted to evaluate the performance of weir mesh,active carbon on fiber(ACOF),polypropylene multi face ball,coal cinder,which are employed as packing media of biotrickling filter The biofilm on the every packing media surface was cultured in same portion of a operating biotrickling reactor under same substrate and nutrient condition Then,equal amount of each packing media was used to make sorption and degradation curve in parallel The ratios of biomass on the each media surface are mesh∶ACOF∶polypropylene multi\|face ball∶coal cinder=7 14∶9 52∶2 05∶1,the ratios of half\|degradation time among each media degradation curve are mesh∶ACOF∶polypropylene multi\|face ball∶coal∶cinder=0 43∶0 5∶0 7∶1 ACOF,which has a certain adsorption capacity,as a bio\|carrier,display better buffering and recovering performance than others after a period of no\|use Short period of no\|use(such as 24 hours)cause no obvious performance deterioration of all biofilm on every packing media
