摘要
采用盆栽试验方法,研究了菌群与三种植物(高羊茅、紫花苜蓿、三叶草)联合修复多环芳烃污染土壤的效应。结果表明,植物在修复中起重要作用,加菌群的土壤中PAHs的去除率高于未加菌群的处理。种植高羊茅加菌群、紫花苜蓿加菌群、三叶草加菌群处理土壤中PAHs去除率分别为41.8%、34.5%和27.1%植物体内有高分子量PAHs的积累,四环PAHs的含量高于五环PAHs。
A PAHs-degrading consortium and three plants（ Festuca arundinacea,Melilotus cinalis and Lolium multiflorum）were used in remediation of PAHs-contaminated soils. During the 60-days pot experiment,the removal of PAHs in the soil grown with the plants was significantly higher than that without plant growth. The consortium enhanced the degradation of PAHs. In the treatment grown F. arundinacea with addition of the consortium,the degradation of 3-,4-,and 5-rings PAHs amounted to 60. 9%,44. 5% and 33. 7%,respectively.
