摘　　要：采用3种不同载体(海藻酸钠、聚乙烯醇、复合载体),分别将小球藻和栅藻与活性污泥固定成菌藻共生系统,制成菌藻凝胶小球,单独菌、单独藻的凝胶小球,用于处理人工污水。结果表明,(1)复合载体固定的菌藻共生系统氮磷去除效果最好,PVA载体的脱氮除磷效果次于复合载体优于海藻酸钠;(2)固定化菌藻共生系统的脱氮除磷效果明显优于单独固定菌和单独固定藻,固定菌的效果较差;(3)3种载体包埋下的固定化小球藻的脱氮除磷效果均较相同载体固定化的栅藻效果好。Three kinds of carriers,including alginate-sodium,polyvinyl alcohol and composite carriers,were used to coimmobilize bacteria-algae system.Chlorella pyrenoidosa and Scenedesmus obliquus as two kinds of algae were used in the experiment.Then bacteria was obtained from activated sludge.Coimmobilized bacteria-algae system,immobilized algae system and immobilized bacteria system were respectively made to treat synthetic wastewater.The results showed that：（1） compared to polyvinyl alcohol and alginate-sodium,bacteria-algae system immobilized by composite carrier had the best nitrogen and phosphorus removal efficiency,and bacteria-algae system immobilized by polyvinyl alcohol had better removal efficiency than that immobilized by alginate-sodium.（2） Coimmobilized bacteria-algae system had better nitrogen and phosphorus removal efficiency than immobilized algae system and immobilized bacteria system,and immobilized bacteria system had lower removal efficiency than the other two.（3） The Chlorella pyrenoidosa immobilized by three kinds of carrier had better nitrogen and phosphorus removal efficiency than Scenedesmus obliquus.
