| 摘 要： | 污染土壤的生物修复技术是一种经济高效的恢复土壤功能的方法。针对地沟式污水土地处理系统的土壤受体,采用曝气、栽种美人蕉、配施稀土La3+等措施对污染土壤实施修复技术。其中曝气使污染物NH3-N、TP和COD的去除率分别增加15.11%~15.68%、10.28%~11.21%、17.89%~18.56%。栽种美人蕉的结果是7.65%~8.11%、6.65%~6.98%、5.12%~5.44%。而低浓度稀土处理对污染土壤活性修复略有增效,高浓度处理则明显的表现出对土壤的抑制作用。

| Abstract: | The bioremediation technologies of soil contaminated with by organics are a potential and effective measure.In this paper the aerations, canna planting and rare earth elements La~(3+) applying were adopted in contaminated soil.Result showed the aerations process was a optimizing remediation of soil contaminated by organic pollutants.NH_3-N,TP and COD of contaminated soil may be dislodged to 15.11%～15.68%,10.28%～11.21% and(17.89%～)18.56%.And it was 7.65%～8.11%,6.65%～6.98% and 5.12%～5.44% by canna in planting.The thin rare earth elements was a little effectient,but higher concentration rare earth held back effectient. |
