Wastewater treatability potential of floating and submerged macrophytes

摘要: Eutrophication has become a major problem that water ecosystem currently faces. The overall operability of traditional treatment approach is not high which may lead to more serious pollution damage, so macrophytes have purification effect on quality turned be research hotspot. Submerged or floating strong adaptability and grow rapidly, can effectively remove eutrophication elements such as N, P forth, furthermore possessing aesthetic value. This experiment selected three types submerged picked in Beijing district, Myriophyllum verticillatum Linn., Lemna minor Linn. common ducksmeat herb (Salvinia natans (Linn.) All.), focused their influence removal COD, NO 3 -N, pH, PO 4 3-P, T-N T-P eutrophic water. results showed all verticillatum, Salvinia had certain pollution. However, under the same conditions, was best, followed by herb, worst light T-P. Besides, this also provides related technical support theoretical basis for eutrophication.
