 note = {application/pdf, 論文(Article), Wastewater from the dye industry contains high level of organic nitrogen derived from
urea. Thus, an effective nitrogen removal process is needed to reduce effluent nitrogen
concentration. We have developed a new nitrogen removal process using non-woven
biomass carriers. In this study, we used pile fabrics, which are products of the local
industry in the Wakayama prefecture, instead of non-woven materials as biomass carriers
to improve nitrification rates. Several pile fabrics were then used for nitrification and
continuous nitrification/denitrification experiments. The specific NOx-N production rate
using an acrylic pile fabric was 3.4 times higher than that of non-woven carriers. About
75% nitrification efficiencies were obtained under a T-N loading rate of 0.5 kg-N/m3/day
and a HRT of 10 hours during continuous nitrification using acrylic pile fabrics.
Furthermore, continuous nitrification/denitrification experiments were carried out using
acrylic pile fabrics in a base cloth with a mesh structure to improve the diffusion rates.
Little biomass accumulated on the pile fabric surfaces so a high diffusion rate through the
pile was maintained for long periods. Denitrification efficiencies of 56 and 77 % were
achieved at HRTs of 12 and 19 hours, respectively, with influent concentrations of 200 mg/l
T-N and 450 mg/lTOC.},
