In order to remove different concentrations of suspended sediment, a serial connected system of emerging plants, floatingleaved plants and submerged plants based on spatial distribution of natural water body was constructed by aquatic marcrophytes, such as Cyperus alternifolius, Acorus tatarinowii, Trapa japonica, Ceratophyllum demersum, Hydrilla verticillata and Vallisneria spiralis. Sandy water then flew through emerging plants, floatingleaved plants and submerged plants.
