Nitrogen removal using a polyethylene (PE) sponge biomass carrier was evaluated in afixed-bed reactor for nitrogen removal by the anammox process. The fixed-bed reactor was operated continuously for 240 days. T-N removal efficiencies increased from 38%,67%,72%,74% to 75 % with stepwise increases in volumetric T-N loading rates. A T-N removal rate of 2.8 kg N/㎥/day was obtained after 240 days of operation. After 3 months,anammox biomass fully covered the surface of the PE sponge carrier and the color of thematerial changed from white to red. Following 5 months of operation,biomass proliferated on the surface of the material and a dark-red color was observed. With the obtained results, PE sponge is auspicious biomass carrier for growth of anammox bacteria.
