地沟式污水土地处理和人工湿地中植物对磷去除的效果研究

采用盆栽实验和中试实验系统，研究了地沟式土地处理系统和人工湿地中不同植物对磷的去除效率。结果表明，7种试验植物对生活污水中的磷均有很高的净化率，其中以芋头、菖蒲和岩豆藤3种植物对磷的净化效率最高。同时还对中试各处理槽的不同位置和深度的土壤中的微生物种类和数量进行了分析，进一步阐述了地沟式土地处理系统和人工湿地中植物的除磷机理。

Dephosphorization Efficiency of Plants in Underground-Ditch-Pattern Soil Treament and Artificial Wetland

In the potted and middle -system exp eriments,we researched the dephosp horization efficiency of different plants in un-derground -ditch -pattern soil treatment systemand artificial wetland.All of the seven plants showed high r emoval rate of TP and the best plants are taro,Calamus and rock bean bine.In the same time,we also a nalyzed the kinds and amounts of microbes in the soil of different places and deepnesses o f middle -system.The dephosphoriza tion mechanism of underground -ditc h -pattern soil treatment system and artificial wetland was also further discussed.
