Paper Title:
Study the Effects of Environmental Factors on Simultaneous Nitrification and Denitrification in SBBR
  Abstract

The experiment studies the phenomenon of simultaneous nitrification and denitrification (SND) in SBBR filled with polyurethane as micro-organisms immobilized carriers. Polyurethane fills in SBR as micro-organisms immobilized carriers, formation of a Sequencing Batch Biofilm Reactor (SBBR). Under the anaerobic/aerobic conditions, we studied the effects of C/P, C/N and DO on SND. The results showed that when COD was 400mg/L, C/P was 43.2~50.2, C/N was 9.41~11.9 of the influent, the concentration of DO was 3.31~4.01mg/L, the effect of TN removal was good. When C/P was 46.9, C/N was 10.3, the concentration of DO was 3.58mg/L, the removal rate of TN was 83.71%, TN effluent was 6.45mg/L. TN effluent followed byⅠA standard of “Discharge standard of pollutants for municipal wastewater treatment plant”. DO concentrations impact the forms of nitrogen in the effluent. C/P, C/N and DO play an important role on SND in SBBR filled with polyurethane. Controlling these factors effectively can inhance the effect of nitrogen removal.
