摘要：In this study, a biotrickling filter (BF) packed
with 32 to 64 liters of wood chips with average sizes
2.03cm×2.25cm, wet packing density 470 kg/m3, void fraction
0.57, and specific surface area 300 m2/m3 was tested for the
removal of < 10 ppm THC (total hydrocarbon, expressed as
methane equivalent) in gases vented from a field zeolite rotary
concentrator for waste gas treatment in a TFT-LCD
manufacturing plant. Results indicate that with operation
parameters of EBRT (empty bed retention time) 2.0 s, pH
6.5-8.0, and daily nutrition milk 0.11 L/m3 chips (10 g milk
powder/m3 chips), 50% THC in the influent gas could be
removed. It was estimated that around 0.016 USD is required
for treating 1000 m3 of the vented gas from concentrators with
a gas flow of 2,000 Nm3/min.
