Abstract:
Based on vermiculite as medium,using potted simulation method,the sewage purification effect of 6 kinds of northern trees on TP,TN and COD were compared.The results showed that,these trees showed better purification effect on pollutants.Overall,the purification ability of TP,Salix matsudana Koidz.>Fraxinus mandschurica Rupr.>Ulmus pumila L.>Tilia amurensis Rupr.>Prunus padus L.>Euonymus maackii Rupr.；purification ability of TN,Salix matsudana Koidz.>Prunus padus L.>Fraxinus mandschurica Rupr.>Tilia amurensis Rupr.>Euonymus maackii Rupr.>Ulmus pumila L.;purification ability of COD,Prunus padus L.>Salix matsudana Koidz.>Tilia amurensis Rupr.>Fraxinus mandschurica Rupr.>Ulmus pumila L.>Euonymus maackii Rupr..With the growing time prolonged,the trees of pollutant purification rate was decreased and then tended to be stable.Mechanism of purification and sewage effect for the test herbs and matrix was analyzed at last.
