摘要：The purpose of this study was to design of constructed wetlands for grey water treatment, explains briefly about the necessity of treatment and types of treatment used in general. Further constructed wetland process, types and advantages of constructed wetland are discussed. For the test beds vetiver and canna plants were selected. The root development of vetiver was deep and wide spread compared to canna. Provide artificial mini wetland and to measure the effectiveness of constructed wetland treatment system. Study was also conducted to evaluate the effect of plant through comparing removal efficiency of the planted and unplanted constructed wetland system. Test bed was planted with vetiver in 20mm gravel root zone media and another set up without plants was maintained as a control constructed wetland was subjected to a flow rate corresponding to hydraulic retention time of 2, 4 and 6 days respectively. The removal efficiency achieved for 79.44% BOD, 83.65% COD, 33.31% Nitrate, 34.54% phosphate, 88.78% SS and 51.99% turbidity for 6 dyas vetiver grass and 74.82% BOD, 79.14% COD, 42.28% Nitrate, 32.93% phosphate, 83.15% SS and 51.99% turbidity for 6 days canna grass.
