Study on Affecting Factors of Simultaneous Nitrification and Denitrification in Moving-bed Biofilm System
|
Abstract:
The phenomenon of simultaneous nitrification and denitrification(SND) has taken place in moving-bed biofilm reactor(MBBR) steadily.The effect of C/N to denitrification effectiveness has been also studied in the experiment.The results of the treatment show that better denitrification efficiency could be obtained by increasing C/N ratio and the removal ratios of TN reached 92.9%.When C/N ratio is 12,the amplitude of TN removal ratio is not obvious.The effects of pH to ammonia nitrogen and TN removal ratio hav...
