Abstract This study investigated pollutants (fluoride, chloride, nitrate, ammonia, phosphates, sulphate and total and volatile solids) removal efficiency from domestic wastewater and plant growth during 195 days in domiciliary constructed wetland (DCWs) microcosms. DCWs were planted with monoculture of Canna hybrid, Alpinia purpurata and Hedychium coronarium and polyculture of the same ornamental flowering plants (OFP), having river rock as a porous substrate. All OFP survived in the DCWs conditions without physical damage. C. hybrid showed the highest length and volume of roots and the highest height and number of flowers than other species in both, mono and polyculture systems. H. coronarium, did not produce flowers. A. purpurata grew better in monoculture than polyculture. Ammonia nitrogen removal was significantly higher in DCW microcosms with monocultures of C. hybrid than with monocultures of A. purpurata (p = .037), but no significantly different than monocultures of H. coronarium (p = .466), Contrary, removal efficiency of this ion was significantly higher in polyculture than mocultures of A. purpurata (p = .024) and H. coronarium (p = .0.032) but no significantly different than monoculture of C. hybrid.The other parameters were removed similarly in both cultures of plants (20–81%; p > .05). Polycultures of OFP are a good option for wastewater treatment in DCWs.

热带观赏植物单养与混养户籍人工湿地微环境中植物生长及废水污染物去除

摘要 本研究调查了住宅人工湿地 (DCWs) 微观世界中 195 天内生活废水和植物生长中污染物（氟化物、氯化物、硝酸盐、氨、磷酸盐、硫酸盐以及总固体和挥发性固体）的去除效率。DCWs 种植美人蕉杂种、紫花山姜和 Hedychium coronarium 的单一栽培以及相同观赏开花植物 (OFP) 的混合栽培，以河石作为多孔基质。所有 OFP 都在 DCW 条件下幸存下来，没有受到物理损坏。C. hybrid 在单一和混养系统中显示出最高的根长度和体积以及最高的高度和花数。H. coronarium，没有产生花。A. purpurata 在单一栽培中比混合栽培生长得更好。DCW 微观世界中，C. 杂种单一培养物的氨氮去除率显着高于 A. purpurata 单一培养物 (p = .037)，但与 H. coronarium 单一培养物 (p = .466) 无显着差异，相反，去除效率这种离子在混杂培养中的浓度显着高于 A. purpurata (p = .024) 和 H. coronarium (p = .0.032)，但与 C. hybrid 的单培养没有显着差异。 其他参数在两种培养中类似地去除植物 (20–81%; p > .05)。OFP 的混养是 DCW 废水处理的一个很好的选择。该离子的去除效率在混合培养中显着高于 A. purpurata (p = .024) 和 H. coronarium (p = .0.032)，但与 C. hybrid 的单一培养没有显着差异。两种植物培养物 (20–81%; p > .05)。OFP 的混养是 DCW 废水处理的一个很好的选择。这种离子的去除效率在混养中明显高于 A. purpurata (p = .024) 和 H. coronarium (p = .0.032)，但与 C. hybrid 的单一培养没有显着差异。两种植物培养物 (20–81%; p > .05)。OFP 的混养是 DCW 废水处理的一个很好的选择。
