摘　　要：在CAST反应器中引入自制悬浮填料,构成了CAS-BT复合反应器,采用人工配制废水,对其除磷效果进行了试验研究。当进水TP为25mg/L左右时,经历了近80d时间的试验运行,TP的去除率高达99%左右,显示出CAS-BT工艺具有很强的除磷能力。试验发现:原水中含磷量越高聚磷微生物数量越多,系统聚磷能力越强。CAS-BT hybrid biological reactor was constituted with self-made suspended media as cartier in the CAST reactor. The performance of phosphorus removal in hybrid biological reactor was studied by experiments. When influent TP was about 25mg/L in the raw wastewater, removal efficiency of TP could be up to 99~,6 by 80 days., which indicated that the capacity of phosphorus removal was strong in CAS-BT process. It was found that the more the phosphorus in raw wastewater was, the more the phosphorus accumulating bacteria were, which would result in the capacity of phosphorus removal much stronger.
