Water purification capacity of different submerged plants
Four kinds of submerged plants,i.e, Vallisneria natans,Hydrilla verticillata ,Potamge-ton malaianus and an improved variety of V. natans,were used as test materials to study their purifying effects on water quality. The results showed that all tested plants exerted some purifying effects on dominant water pollutants. The improved variety of V. natans had the best comprehensive purification capacity and its rates of purifying the water of TN.TP and CODMn were 65.1%,57.7% and 17. 3% .respectively.The water purification capacity of P. malaianus was medium,and that of H. verticillata was relatively poor.
