Three types of odour abatement systems in sewer networks in Australia were studied for 18 months to determine the removals of different compounds. Six volatile sulfurous compounds and seven volatile organic compounds (VOCs) were further investigated. All types of odour abatement systems exhibited good removal of hydrogen sulfide with the biotrickling filters (BTFs) showing the highest consistent removal. Biofilters outperformed BTFs and activated carbon (AC) filters in the removal of dimethyl mono-, di- and tri-sulfide species at the low inlet concentrations typically found. AC filters exhibited little VOC removal with no compound consistently identified as having a removal greater than 0%. Biofilters outperformed BTFs in VOC removal, yet both had high removal variability.
对澳大利亚下水道网络中的三种气味消除系统进行了为期18个月的研究,以确定不同化合物的去除情况。进一步研究了六种挥发性含硫化合物和七种挥发性有机化合物(VOCs)。所有类型的气味消除系统对硫化氢均表现出良好的去除效果,其中生物滴滤池(BTF)的去除效果最为稳定。在通常发现的低入口浓度下,生物滤池在去除二甲基单硫化物、二硫化物和三硫化物方面优于BTF和活性炭(AC)过滤器。AC过滤器对VOC的去除效果甚微,没有一种化合物的去除率始终高于0%。生物滤池在VOC去除方面优于BTF,但两者的去除率变化都很大。
