| Tolerances of aquatic plants (emergent plants) of cattail (Typha orientalis), water oats (Zizania latifolia), reed (Phragmites communis), and bulrush (Scirpus nipponicus) to salts and high NH©þ/sup £«/-N cone. of industrial wastewater were evaluated. Evapotranspiration of cattail and water oats plants was not affected when the wastewater containing 130 ppm NH©þ/sup £«/-N with electrical conductivity of 3.0 dS/m was supplied for 5 months. Shoot and root dry wt. of cattail and water oats were rather increased by irrigation of the wastewater while the biomass production of bulrush was greatly reduced. Storage nitrogen concentration in tissues of water oats and reed plants were higher than those in cattail and bulrush. Thus, water oats and reed plants were found to be the better aquatic plants to use in constructed wetlands for treating industrial wastewater of high salt and NH©þ/sup £«/-N. |
