The optimal preparing condition was each of the peat and PVA aqueous solutions mixed with 6.4g KNO3, and the minimum nitrogen content in the boric and phosphate aqueous solutions was 3.94 and 1.52g-N/l, respectively. The equilibrium amount of inorganic nitrogen extracted by leaching from the prepared composite bead was between 7.95 and 8.21mg N/g dry solid. The path of inorganic nitrogen extracted by leaching was the inorganic nitrogen dispersed in the peat phase firstly diffused into the outer PVA phase and then it diffused out of the bead surface for the A-type bead; and that was the inorganic nitrogen dispersed in both the peat and PVA phases simultaneously diffuses into the outer PVA phase and out of the bead surface, respectively, for the H-type bead. The microbial growth rate k g of the H-type composite bead was higher than that of the A-type composite bead about 1.09-1.58times, and the maximum value of k g was at the H-type composite bead immersed in 0.384M KNO3 aqueous solution. The percentage of removed VOCs retained at more than 98% during the biofilter operating 230days as the composite bead immersed in KNO3 aqueous solution before packing. This composite bead bed was without the further addition of nutrients during the operating period.
