Study on Influencing Factors of Biological Phosphorus Removal with Glucose as Carbon Source

The effect of the SRT,pH value,temperature and anaerobic stirring on biological phosphorus removal process in SBR fed with glucose was studied in this paper.The phosphorus removal effect was also compared with that in the systems applying sodium acetate or coating wastewater of automobile manufacturing as the major substrate.The results indicated that short SRT can increase phosphorus removal significantly;the optimal pH ranged from 6.5 to 7.5;change of temperature had little effect on the phosphorus removal;and anaerobic stirring adopted at the anaerobic reaction step can improve anaerobic phosphorus release.It is found that phosphorus removal effect was the worst in the system applying coating wastewater of automobile manufacturing as the major substrate.
