Constructed Landscaping combination constructed wetlands System Used for sewage treatment

摘要：

We constructed a combinant landscape constructed wetland for sewage treatment based on landscape plants in this study.The results are summerized as follows: the system uses model as:A(biological pretreatment pond)-B(biochemistry pond)-C(subsurface flow wetland)-D(surface flow wetland)-E(the thirdlevel vertical-flow wetland)-F(second-level verticalflow wetland) -G(landscape surface flow wetland)-H (biology pond); this combination craft sewage treatment is performed effectively, and the system outcome water quality achieves the first-level A standard. In this system, through plants screening, we found out the nearly 30 plants fitted the system with high compatibility, strong purification, high landscape value and high economic value, which were Mainly:Cannaindica,Iris ensata,Acoruscalamus,Iris tectorum,Iris germanica,Thalia dealbata,Cyperus alternifolius,Juncus effusus,Pontederia cordata,Phragmites australis,Pennisetum purpureum,Paulownia tomentosa,Ipomoea aquatica,Zephyranthes candida,Liriope spicata,Lolium perenn,Oenanthe clecumbens,Trifolium,Reineckiacarnea,Cuphea ignea,Salix babylonica,Fatsia japonica,Lucidum Ait,Cuphea ignea,Lythrutn salicaria,Metasequoia glyptostoboides.Eichhornia crassipes,Salvinia natans,Nelumbo nucifera,Nymphaea tetragona,Nymphoides peltatm.
