Abstract

The performance of trickle-bed air biofilter (TBAB) for the removal of isopropyl alcohol (IPA) was evaluated in concentrations varying from 100 to 500 ppmv and at empty-bed residence time (EBRT) varying from 20 to 90 s. Nearly complete IPA removal could be achieved for influent carbon loading between 6 and 88 g/m3 x h. The TBAB appears efficient for controlling IPA emission under low-to-high carbon loading conditions. Carbon recoveries of 95-99% were achieved demonstrating the accuracy of results. Applicable operating conditions of TBAB for controlling IPA emission were suggested.

摘要

评估了滴流床空气生物滤池（TBAB）在浓度为100至500 ppmv且空床停留时间（EBRT）为20至90秒的条件下去除异丙醇（IPA）的性能。对于6至88 g/m³·h的进水碳负荷，几乎可以实现IPA的完全去除。TBAB在低至高碳负荷条件下似乎对控制IPA排放有效。实现了95%至99%的碳回收率，证明了结果的准确性。提出了TBAB控制IPA排放的适用操作条件。
