Abstract

The system performance of a trickle-bed air biofilter (TBAB) for treating N,N-dimethylacetamide (DMAC) waste gas was investigated under different gas flow rates and influent concentrations. In the pseudo-steady-state conditions, the DMAC elimination capacity increased but the removal efficiency decreased as the influent loading increased. More than 90% and 80% DMAC removal efficiencies are achieved for influent loadings below 20.2 and 34.5 g DMAC/m3/h, respectively. The TBAB appears to be an effective treatment process for controlling DMAC emission with low-to-medium loadings and the effectiveness could be maintained over a long-period operation.

摘要

研究了滴流床空气生物滤池（TBAB）在不同气体流量和进水浓度下处理N，N-二甲基乙酰胺（DMAC）废气的系统性能。在准稳态条件下，随着进水负荷的增加，DMAC去除容量增加，但去除效率降低。进水负荷分别低于20.2和34.5 g DMAC/m³/h时，DMAC去除效率分别超过90%和80%。滴流床空气生物滤池似乎是控制中低负荷DMAC排放的有效处理工艺，且该有效性可在长期运行中得以维持。
