摘　　要：以现已成熟的美国AquaMats生物膜技术为参比,比较不同材质或结构为载体的藻-菌生物膜技术改善富营养水体的效果。结果表明:对TN、TP、CODMn、NH4+-N、透明度等指标的处理效果顺序基本为条形水草>AquaMats>人工水草>植物地毯>对照组,其中条形水草对TN、TP、CODMn的去除率分别为97.3%、77.1%、63.3%,第22d将透明度由25cm提高到85cm。大多数膜处理能将DO维持在4mg/L以上。条形水草的藻-菌生物膜技术对富营养水质改善效果最明显,且成本低廉,值得推广。Taking the mature biofihn technology of American AquaMats as a reference, the effects of improving the eutrophication water body by algae-bacterium biofihn with different materials or setting modes as carries was compared. The results showed that for TN,TP,CODMn NH4^＋-N and the transparency the sequence of treating effect is basically： strip aquatic mats〉 AquaMats〉 artificial aquatic mat〉plant carpet〉the control; in it the removal rates of TN,TP,CODMn by strip aquatic mats were 97.3%,77.1%,63.3% respectively; on the 22th day, transparency increased to 85cm from 25cm; most treating modes could keep DO at the level above 4 mg/L; the algae-bacterium biofilm technology with strip aquatic mats has the most marked effect of improving the eutrophication water body with low cost and is worth being popularized
