Effects of Purification Highly Salty Reuse Water Quality by Three Plants in TEDA Landscape River

The effects of purification highly salty reuse water quality are studied by three plants-scirpus tabemaemontanii Gmel, Typha and Canna indica Linn in Tianjin-Economic and Technology Development Area Landscape River. The resuits show that hydraulic retention time has obviously influence on the effects of purification highly salty reuse water quality. Moreover, removal rates of all kinds of contamination vary with HRT, such as removal rate of COD, TN, NH3 - N, NO3-N, TP, PO4-P is 14.47 % -45.09% 25.50% -71.00% ,39.96% -82.47 %, 27.21% -74.41%, 38.91% -90.01%, 38.55% -92.01% respectively. Both the three plants grow and effects of purification of the highly salty reuse water treatment systems operate very well while concentration of TDS is about 4 500 mg/L in the water; pH of effluent water plants is lower than influent. Removal rates of Phosphorus by Scirpus tabernaemontanii Gmel and Typha are higher than its by Canna indica Linn when the HRT is sameness. The reason that Scirpus tabernaemontanii Gmel and Typha are planted with wetland while Canna indica Linn grows in water, at the same time phosphorus is removed from water because of the function of soil adsorption and so on. The rates of removal contaminations else are invariable by the three plants.
