Abstract :
A novel non-woven rotating biological contactor reactor (NRBC) was started up to enrich anammox bacteria. Research results showed that after 100 days´ operation, the nitrogen removal rate was arrived as high as 3.4 kgNm-3d-1 in the condition of HRT 4 h, influent ammonium and nitrite concentration 350 mg L-1. Scanning electron micrograph (SEM) showed that the typical cauliflower aggregates were tightly attached on the support material. It has been proved that NRBC reactor is a very suitable experimental set-up for the enrichment of anammox bacteria.
