摘要： 研究旨在筛选对邯郸市乡村河道水体净化效果较好的生态浮岛植物组合模式,主要研究静态条件下,多种植物进行不同组合搭配的生态浮岛对乡村河道水体的净化效果,选取水葫芦、再力花、美人蕉、慈姑、水芹作为供试植物,比较5种组合对水体中COD、TP、NH4+-N等污染物的去除效率。经过38d试验,结果表明：水芹+慈姑+美人蕉+水葫芦、美人蕉+再力花+水葫芦对COD去除率较高,分别为35.5%、31.2%；水芹+慈姑+美人蕉+水葫芦、美人蕉+再力花+水葫芦对TP去除率较高,分别为81.6%、77.3%；水芹+慈姑+美人蕉+水葫芦、水葫芦+再力花+美人蕉+水芹对NH4+-N去除率较高,分别为55.4%、53.9%；混合植物型生态浮岛对乡村河道水体的净化有显著效果。

Abstract: The objective of the study was to screen the ecological floating island plantation model that has a good purification effect on the rivers in the villages of Handan City. Mainly studied under static conditions, the effect of ecological floating islands with different combinations of different plants on the purification of rural rivers, select Eichhornia crassipes, Thalia dealbata, Canna indica, Sagittaria and Oenanthe javanica as test plants, and compare the removal efficiency of COD, TP, NH4+-N and other pollutants in water by five combinations. After 38 days of testing, the results show that: Oenanthe javanica + Sagittaria + Canna indica+ Eichhornia crassipes, Canna indica + Thalia dealbata + Eichhornia crassipes had higher removal rates of COD, which were 35.5% and 31.2%, respectively. The removal rate of TP was higher with Oenanthe javanica + Sagittaria + Canna indica + Eichhornia crassipes, Canna indica + Thalia dealbata + Eichhornia crassipes, which were 81.6% and 77.3% respectively. The removal rates of NH4+-N were higher with Oenanthe javanica + Sagittaria + Canna indica + Eichhornia crassipes, Eichhornia crassipes + Thalia dealbata + Canna indica + Oenanthe javanica, which were 55.4% and 53.9%, respectively. The mixed plant-type ecological floating island has a significant effect on the purification of rural river water bodies.
