The paper selected six kinds of plants including canna generalis, canna glauca, cyperus alternifolius, iris tectorum, iris iacteal, acorus calamus linn from situ ecological restoration engineering field of Dagu sewage river as research object. Greenhouse cultivation test was carried out to study the remediation effect of six plants on nitrogen, phosphorus and heavy metal of Cd and Pb. The result showed that all the 6plants showed good remediation effects on the water pollution. The removal rates of the plants are 53.90~94.75% to TN, 46.76~85.10% to TP, and 90.39~99.47% to Cd. Acorus calamus linn, iris tectorum and Iris lacteal shows good remediation effect on TN; the remediation effects of iris tectorum, canna and iris iacteal on NH4[KG-*3]+-N are better; and cyperus alternifolius, canna and iris iacteal are best choices on TP remediation. The enrichment factor of six kinds of plants on Cd and Pb is far greater than 1, which means strong accumulation ability of plants on Cd and Pb. The plants can be used as hyperaccumulator of Cd and Pb to deal with the heavy metal pollution in contaminated water body.
