摘　　要：为了解固定化溶藻菌对藻类污染水源的治理效果,模拟动态膜生物反应器,将溶藻细菌RZ14菌株固定于膜组件,通过膜自生功能形成溶藻菌生物膜。采集水华水体作为进水水样,对水体中叶绿素a、有机质、氨氮及总磷变化进行跟踪测定。结果表明:结合DMBR工艺,投加溶藻菌RZ14菌株后,叶绿素a含量低于0.05mg/L,去除率接近100%,COD及BOD5去除率分别为50.08%和71.24%,氨氮及总磷去除率分别为70.73%和86.79%。将溶藻菌投加动态膜生物反应器,能快速消除水华现象,改善水质污染状况,对藻类污染水体治理效果显著。In order to investigate the algae removal effect,algacidal bacteria strains RZ14 were immobilized on a membrane module to simulate the performance of self-forming dynamic membrane bioreactor（DMBR）. The influent was collected from an algal bloom water body, and the concentration changes of chlorophyll a, organic matter, ammonia nitrogen and total phosphorus were determined. After the immobilization of bacteria strains RZ14,chlorophyll a was almost totally removed,whose concentration was lower than 0. 05 mg/L,while the removal efficiencies of COD,BOD5,ammonia nitrogen and total phosphorus were 50. 08%,71. 24%,70. 34%,and 86. 79%,respectively. The result showed that immobilized algacidal bacteria in DMBR could quickly eliminate algal bloom,which had a good application prospect in eutrophication control.
