The analysis of biofiltration efficiency was performed with parallel VOC, H₂S and NH₃ removal using pilot two-stage biofilters including conventional biofiltration and purification on a membrane filter. The scope of the research was to determine the relationship between the technological parameters of the tested device (two beds and two membranes) and gases removal efficiency. Research was carried out in a semi-technical scale in three industrial plants: mechanical-biological municipal waste treatment (MBT), food industry (FI) and wastewater treatment (WWTP) plants. Experimental results indicate the efficiency removal of VOCs from 89% (WWTP) to 98% (FI), NH₃ from 88% (WWTP) to 100% (MBT) and H₂S from 93% (WWTP) to 100% (MBT). Biofilter with stumpwood chips-bark-compost bed, fortified with the more porous membrane was the most effective, allowing VOC, NH₃ and H₂S removal with an average efficiency of 99% for NH₃ and H₂S and 97% for VOCs. The application of membrane fabrics as the second stage of purification allows high efficiency simultaneous removal of VOCs, NH₃ and H₂S. Unlike two-stage purification, conventional biofiltration is effective at removing individual impurities from process gases. The results of this study indicate a high potential for practical application.

使用中试两级生物滤池（包括常规生物滤池和在膜滤池上纯化）的平行VOC，H ₂ S和NH ₃去除率对生物滤池效率进行分析。研究的范围是确定被测设备（两个床和两个膜）的技术参数与除气效率之间的关系。在三个工业工厂中以半技术规模进行了研究：机械生物市政废物处理（MBT），食品工业（FI）和废水处理（WWTP）工厂。实验结果表明，VOC的去除效率从89％（WWTP）降至98％（FI），NH ₃从88％（WWTP）降至100％（MBT）和H ₂S从93％（WWTP）到100％（MBT）。生物滤池与stumpwood芯片树皮堆肥床上，用多个多孔膜强化是最有效的，允许VOC，NH ₃和H ₂小号去除99％的平均效率为NH ₃和H ₂ S和97％为挥发性有机化合物。膜织物的作为纯化的第二阶段中该应用程序允许高效率同时去除挥发性有机化合物，NH的₃和H ₂与两阶段纯化S.，常规生物过滤是在从过程气体中去除单独杂质有效的。这项研究的结果表明有很高的实际应用潜力。
