Abstract

The effects of air/water ratio, hydraulic load, temperature and C/N ratio on nitrogen removal efficiency of aerobic denitrifies in bio-ceramic reactor were investigated. Denaturing Gradient Gel Electrophoresis (DGGE) was used to analyze the stability of microbial community structure. 93.10% of nitrate nitrogen removal efficiency and 97.50% of COD removal efficiency could be reached under conditions of hydraulic load 1.5 m/h air/water ratio 5:1, temperature 25-30 °C nitrate nitrogen loading 0.75-2.87 kg/(m³ · d),COD loading 7.46-10.03 kg/(m³ ·d). DO and nitrate nitrogen concentration were reduced at the region 0-0.5 m from the influent, and DO was always kept at a high level for all experiment. The aerobic denitrifies strains were identified with 16S rDNA. The PCR-DGGE profiles showed that the isolated four strains belong to Pseudomonas and the preponderant populations were dominant population in aerobic denitrification.
