Abstract

In this study, a novel biological filler was prepared. The physicochemical properties and performances on treating NOx were investigated compared with corncob and ceramsite in three biofilters. The new filler could provide nutrients for the microbe and could prevent the large fluctuate of pH. Compared with the two other materials, the new synthetic packing material (MCP) had a lowest pressure drop. The maximum removal capacities of NOx could reach to 2318, 1115 and 624 mg m-3 h-1 for MCP, corncob and ceramsite filler when the EBRT was not less than 36 s. Besides, the experimental datum were modeled using the modified Michaelis-Menten model and Ks and Vm had been calculated from the model equation.
