| 摘 要： | The effects of Tween-20 and Zn（II） on ethylbenzene removal were evaluated using two biotrickling filters（BTFs）, BTF1 and BTF2. Only BTF1 was fed with Tween-20 and Zn（II）.Results show that ethylbenzene removal decreased from 94% to 69% for BTF1 and from 74%to 54% for BTF2 with increased organic loading from 64.8 to 189.0 g ethylbenzene/（m3·hr） at EBRT of 40 sec. The effect of EBRT（60–15 sec） at a constant ethylbenzene inlet concentration was more significant than that of EBRT（30–10 sec） at a constant organic loading. Biomass accumulation rate within packing media was reduced significantly.
