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.
