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,对其同步脱氮除磷效果进行了试验研究。试验结果表明,当TN为178.05 mg/L、TP为28.32 mg/L时,CAS-BT工艺取得了很好的同步脱氮除磷效果,TN和TP的去除率分别达到97.55%和98.10%。进行同步脱氮除磷时,CAS-BT比其他的水处理工艺更具优势。The biofilm using self-made suspended media as carrier was put in the CAST reactor, then a CAS-BT hybrid biological reactor was constituted. The effect of simuhaneous removal of nitrogen and phosphorus in CAS-BT hybrid biological reactor was studied. When the concentration of TN and TP was about 25 mg/L and 180 mg/L respectively in the raw wastewater, the result of simultaneous removal of nitrogen and phosphorus was good and the removal rates of TN and TP could reach to 96.46% and 98. 10% , respectively. It proved that there were advantages for CAS-BT in the process of simultaneous removal of nitrogen and phosphorus. nitrogen and phosphorus
