摘　　要：对菌藻共固定化系统进行研究,初步确定菌藻共固定化中较佳的污泥包埋量。在同等条件下,固定化菌藻对氮磷的去除效果优于固定化细菌和固定化藻类的去除效果。对氨氮和磷酸盐磷去除能力的48 h实验结果表明,按去除率的大小排列为:固定化菌藻>固定化小球藻>固定化细菌,固定化菌藻对NH4+-N和PO43--P的去除率分别达到97.09%和88.69%,可见把细菌和藻类共同包埋于同一载体内,在同时去除污水中的氮磷和有机物方面有着更大的优势。Through the investigation of activated sludge in the co-immobilized bacteria-algae system,the optimal quantity of buried sludge in co-immobilized bacteria and algae was tentatively determined.Under the same conditions,more NH4＋-N and PO3-4-P were removed by the co-immobilization of bacteria and algae than by using immobilized bacteria or immobilized algae alone.The results of a 48-hour experiment of removing NH＋4-N and PO3-4-P showed that the ranking of the removal rate was co-immobilized bacteria-algae system〉immobilized chlorella〉immobilized bacteria,and the removal rates of NH＋4-N and PO3-4-P by co-immobilized bacteria-algae reached 97.09% and 88.69%,respectively.It is proposed that co-immobilization of a microalgae with bacteria is a superior tool for removing nitrogen,phosphorous,and organic matter in wastewater.
