Abstract  

A wetland plant screening was constructed at Yanqing County,Beijing to simulate the effectiveness of 7 natural wetland plants and their combinations in purifying eutrophic water and removing TP,TN and COD.The results showed that the purification effectiveness of wetland plants and any of their combinations were not significantly different(P>0.05) for COD,TN and TP;no significant difference(P>0.05) exists on COD purification between summer and autumn,except for Typha orientalis(P<0.05).These 7 wetland plants and 7 combinations showed 1) higher effectiveness on TN removal in summer than in autumn;2) no significant difference on TN purification between summer and autumn(P>0.05),except for Phragmites australis+Menyanthes trifoliate,Typha orientalis+Salix viminalis(P<0.05);3) no significant difference on TP purification by any individual wetland plant between summer and autumn (P>0.05);4) no significant difference on TP purification between summer and autumn,except for Typha orientalis+Zizania aquatic,Phragmites australis+Menyanthes trifoliata(P<0.05);5) but a significant difference on TN purification among 7 different wetland plants combinations(P<0.1).
