Abstract: This paper compares the operating performance of bio-trickling filters packed with ceramsite and those packed with mixed loading of ceramsite and multi-faceted hollow balls called Hacketten in treating benzene-containing waste gas.And the experimental results indicate that ceramsite packing showed better benzene removal performance than that packed with mixed loading of ceramsite and Hacketten.During operation,the pressure drop of bio-trickling filter was higher than that of the one packed with mixed loading of ceramsite and Hacketten.
