摘要: Vertical-flow constructed wetland (VFCW) is an effective alternative for removal of nutrients, heavy metals, and organic pollutants from wastewaters. This study investigated the uptake total phosphorus (TP) by Cyperus alternifolius domestic wastewaters in simulated VFCWs. The eight VFCW treatments, including two different substrates, wet-to-dry ratios, with without C. species (2 × 2 = 8), were utilized operation period years this study. Results show that about 1.1 to 1.4 times more TP was removed influent presence as compared plant species. A linear correlation existed between aboveground biomass its content. An increase 1000 g would result accumulation 4.9g. Large amounts substrate adsorption those biomass. Result...
