摘要
Abstract
A four beds wavy flow wetland was constructed to investigate the treatment performance of constructed wetlands individually planted Cyperus alternifolius and Canna generalis for breeding wastewater. The results show that the average removals of SS, COD, NH4+-N, TN and TP were 76% , 77% , 78% , 77% and 72% , respectively. The biomass and nitrogen/phosphorus contents of C. Generalis were higher than those of C. Alternifolius. Nutrient-distribution in plants tissues were leaf > root > stem. Heavy metal levels in plants were Zn > Pb > Cu > Ni > Cr. Zn, Pb, Ni and Cu distributions in plants tissues were root > stem > leaf or below-ground tissues > above-ground tissues that was opposite for Cr.关键词
