Abstract :

Constructed wetlands are in use since the early 1950s and prove to be effective in the treatment of wastewater. There are several other terrestrial plant species which are equally effective as that of wetland plants. Also, vertical flow wetlands have had a history of significantly reducing the organic matter contents as well as microbial species by providing more oxygenated environment, from wastewater. For Vertical subsurface flow constructed wetland, removal efficiency and mass removal rate of pollutants were considerably high. A model house with 3 x 3 x 2.5 m of length, width and height was established with constructed wetland. The sewage produced was passed through the constructed wetland and its efficiency was analyzed at the same time monitoring the differential temperatures between inside and outside of the model house. The artificial wetland consists of breakstone and gravel etc as well as plants. New-type multi-layer artificial wetland is proposed for the treatment of domestic sewage and COD, BOD, NH3-N, TN, TP removal, when the hydraulic loading reaches approximately 0.44 m3/(m2 d) and hydraulic retention time (HRT) reaches 3 days the removal efficiencies are 90.6%, 87.9%, 66.7%, 63.4% and 92.6%.
