Study of the Nitrogen and Phosphorus Removal Effects in SBBR by Microbial Immobilization Technology

Abstract:

This study filled polyurethane foam in SBR as micro-organisms immobilized carrier, formed a sequencing batch biofilm reactor (SBBR). It applies the immobilized microbial technology to SBBR, under the A/O operation mode，we cultivate them in order to study the effect of the technology of nitrogen and phosphorus removal in the domestic sewage. The carrier which was used in the SBBR, created aerobic - anoxic - anaerobic micro-environment in space, and appeared a good performance of simultaneous nitrification and denitrification (SND). The results show that adding this kind of carriers in SBBR, successfully achieved a goal in the field of nitrogen and phosphorus removal. The average removal rates of COD_Cr, NH₄⁺-N, TN and TP is respectively 84.23%、96.94%、58.40% and 91.38%.
