%X The composite biofilter(a combination of biotrickling filter and biofilter),taking surfactant-modified clinoptilolite and wood chip as the media respectively,was applied to treat the mixed odors(H_2S and NH_3).The microbial acclimation and the process conditions were studied.The results indicated that the period of packing biofilm was 10~14 d with surfactant modification,which shortened 14~18 d,compared to the activated carbon used in literatures.The optimum height and recycle liquid rate of composite biofilter were 120 cm and 4.56 L/h,respectively.The biotrickling had better removal efficiency for hydrophilic NH_3 than biofilter,while the biofilter had better removal efficiency for hydrophobic H_2S than biotrickling filter.Therefore,the composite biofilter could be used to treat the mixed odors.
