【摘要】 为了研究鲍尔环/阶梯环填料对H2S废气净化效率的影响,分别以装有两种填料的生物滴滤塔来进行对比研究,指出对于净化含H2S恶臭气体的生物滴滤塔,应选用具有结构合理、比表面积大、空隙率大、堆积重量轻、湿填料因子小、化学性质稳定以及价格便宜等性质的填料。更多还原

【Abstract】 A contrastive research on purifying the waste gas mainly consisting of H2S using bio-trickling filter(80×H500 mm) with two different kinds of fillers(pall ring/cascade ring) was done.It points for the bio-trickling filter to purify H2S,the fillers should have following characteristics: desirable structure,big specific surface area and bed voidage,light accumulate weight,small wet packing factor,stable chemical properties and cheap price.更多还原
