Study on the Purification Effect of Aquatic Plant by Artificial Floating Island on Domestic Sewage
[Objective] To study the purification effect of aquatic plant by an artificial floating island method on domestic sewage.[ Method] Cultivating aquatic plant by artificial floating island, through establishing simulated static sewage tank, the removal effects of willow vegeta-bles, aquatic yellow iris, calamus, aquatic canna on COD, ammonia nitrogen, TP were studied.[ Result] In sewage pond, willow vegetables grow best, all plants bloom;plant height of aquatic yellow iris, calamus changed obviously;aquatic canna grow worst, root growth was not obvi-ous, only a few plants flowering, with yellow leaves.For COD, the purification of plants was mainly in the reproductive stage, and for ammo-nia nitrogen and total phosphorus, it was mainly in the vegetative growth stage.The optimal order of four plants was as following, willow vege-tables, aquatic yellow iris(calamus), aquatic canna.[Conclusion] This study can benefit to the optimization of the aquatic plants and the fur-ther research on purification of surface water.
