摘　　要：以滏阳河邯郸段3种水生植物狐尾藻、金鱼藻及篦齿眼子菜为研究对象,通过批式实验,考察植物种类对削减滏阳河原水污染物质的效果,研究3种植物及对照系统对氮、磷、COD_(Mn)等的去除效果。结果表明:经40 d批式实验后,各组反应器对TN,NH_3-N,TP,COD_(Mn)的去除率达62%,64%,42%和67%以上,其中净化效果最佳的植物为金鱼藻;同时,不同植物的含氮量与含磷量与其污染物去除能力不一一对应,但其大小次序与对氮、磷的去除能力基本相似,这可能与植物的吸收作用或植物根系微生物的代谢作用相关。Taking 3 aquatic plants of Myriophyllum spicatum,Ceratophyllum demersum,Potentilla discifolia in Handan reach of the Fuyang River as study subjects,patch tests were conducted to study the elimination effect of nutrient salt comparing with reference group(without plant in water),including nitrogen,phosphorus and CODMn.The results showed that after 40 days tests,the removal rates of TN,NH3-N,TP and CODMn by 3 aquatic plants and reference group were all higher than 62%,64%,42% and 67%.Ceratophyllum demersum was the best in elimination effect.The contents of nitrogen and phosphorus in different plants did not exactly corresponded to the pollutants’ removal effect,but the content orders were basically similar to the elimination effect and the cause may be related to the plants′ absorption or the roots’ microbial metabolism.
