Comparative research on wavy subsurface flow constructed wetland with Phrynium capitatum and Pennisetum purpureum
摘要
Abstract
By building wavy subsurface flow constructed wetland with Phrynium capitatum and Pennisetum purpureum as artificial wetland plant,we studied the growth characteristics of Phrynium capitatum and Pennisetum purpureum,the pur-ification effects of CODcr,total nitrogen (TN) and total phosphorus (TP) in domestic sewage by wavy subsurface flow constructed wetland.The results after fifteen months of continuous running showed that under a condition of hydraulic surface loading for around 0.3 m·d-1,the average removal rate of them were 66.1% and 70.1%(CODcr),60.4% and 63.7%(TN),74.1%and 75.1%(TP).Both plants grew well,the roots were well developed,the aboveground biomass of P.purpureum was 2.1 of Phrynium capitatum,and the underground biomass was quite the same.The growth of P.pur-pureum was slow in the winter,and the part of leaves were dry around with Phrynium capitatum,but they would not wither in winter.The results showed that they had a good purification effect on CODcr,TN and TP without significant difference.Phrynium capitatum and Pennisetum purpureum can significantly improve the purification effect of subsurface flow constructed wetland.关键词
