摘要

针对连续进水生物膜除磷效率低的问题，提出了基于间歇曝气、富磷废水回用和交换进水的连续进水生物膜反应器(CIBFR)。在间歇曝气条件为厌氧3h-曝气6h，温度为20℃，DO=5.5 mg•L-1时，研究了溶解氧(DO)、体积负荷(Nv)和间歇曝气对CIBFR除磷的影响。当进水COD为280 mg•L-1, PO43—P为3.1 mg•L-1时，COD和PO43—P的去除率分别为72.9%和78.5%。

Study on Phosphorus Removal Efficiency of a Continuous Influent Biofilm Reactor (CIBFR) Based on Intermittent Aeration and Rich Phosphorus Wastewater Return

To overcome the low efficiency of phosphorus removal in the continuous influent biofilm, the continuous influent biofilm reactor (CIBFR) which based on intermittent aeration, rich phosphorus wastewater return and commutative influent was proposed in this study. The effects of dissolved oxygen(DO), volume loading (Nv) and the intermittent aeration on phosphorus removal of the CIBFR were investigated when the intermittent aeration was anaerobic 3h-aeration 6h, the temperature=20¿, DO=5.5 mg•L-1. When the influent COD was 280 mg•L-1 and influent PO43--P was 3.1 mg•L-1, the removal rates of COD and PO43--P were 72.9% and 78.5%.
