Abstract:

The purification efficiency of total nitrogen(TN) and total phosphorus(TP) of domestic sewage was researched by testing 19 species of wetland plants along the Songhua River in Jilin City in this paper.The results showed that plants could purify domestic sewage，and the purification ability was varied in different species.Rumex patientia L.var.callosus was the highest in all of tested plants in removal efficiency of total nitrogen (TN，29.14%)；Coleus blumei Benth.could effectively reduce content of total phosphorus (TP)，the highest removal efficiencies for TP was 58.04%，Alisma orientale (Sam.)Juz.,Polygonum thunbergii Sieb.et Zucc.,Coleus blumei Benth.,Iris lactea var.chinensis Thunb,Oenanthe javanica(Blume) DC.could be used as plants for the construction of domestic sewage purification landscape，because these plants had better comprehensive capacity for domestic sewage purification of total nitrogen and total phosphorus.
