The present study was done from the month of January to June in 2019. The aim of this study was to investigate the impact of Domestic wastewater (DWW) on the growth of Phragmites karka and Chrysopogon zizanioides in Constructed wetland and phytoaccumulation of heavy metals. The fresh weight, dry weight, moisture content, relative growth rate and absolute growth rate of plants were calculated by Classical and functional methods. The concentrations of metals were determined by AAS. The wastewater contained higher concentration of Fe and Zn in comparison to Cu and Pb and calculated concentration of Heavy metals in DWW ranged from 2.45 ± 0.01 to 2.92 ± 0.05 for Fe; 70.73 ± 1.2 µgL-1 to 88.33 ± 0.58 µgL-1 for Zn; 0.62±0.01 µgL-1 to 1.09±0.01µgL-1 for Pb and 1.83±0.03 µgL-1 to 2.6±0.12 µgL-1 for Cu. ..
