%X According to nitrogen-containing wastewater, effects of salinity variation on nitrification and denitrification in internal circulation sequencing batch biofilm reactor (SBBR) and sequencing batch reactor (SBR), and the process of recovery as decreased salinity were investigated. The results show that nitrosation process is effected in internal circulation SBBR and SBR as the increase of salinity, and as the salinity is less than 1.0 × 10~4 mg·L~(-1), the speed of ammonia-oxidize is quicker in the SBR than in the SBBR, but the state is opposite as the salinity beyond 1.5 × 10~4 mg·L~(-1) . As the salinity increased to 4.0 × 10~4 mg·L~(-1), the process of ammonia-oxidize was restrained strongly both in SBBR and SBR. The nitrite accumulation is attained continually as the salinity at 1.5 × 10~4 mg·L~(-1) and 2.5 × 10~4 mg·L~(-1) in the SBBR and SBR respectively. In the SBBR, the removal rate of TN was about 60% as the salinity was less than 1.5 × 10~4 mg·L~(-1), and the SND was restrained strongly as the salinity beyond 3.0 × 10~4 mg·L~(-1).
