Pollution Control in Aqueous Solution by Hydroponic Cultivation of Plants

摘要

The primary objectives of the project were to develop a research base to allow professionals in the Corps of Engineers to utilize plant cultivation methods to alleviate and remediate water pollution problems associated with various activities of the Army. A two-fold approach was used. The first involved the design, construction and implementation of pilot scale studies to assess the abilities of plant species, both aquatic and terrestrial, to remove pollutants from low quality waters, such as stormwater runoff from contaminated sites and wastewater. This experimental approach offers the opportunity to quantitatively evaluate plant growth and biomass distribution including the accumulation of dissolved materials in plant organs such as roots, stems, leaves and flowers. The second approach involved utilization of simulated storm and waste water as a source of nutrients for growing a commercial greenhouse crop, in this case a floricultural crop.
