| 摘 要： | 土地生物处理能有效降解土壤中有机污染物多环芳烃 (PAHs) ,构建的基于土壤屏蔽反应机理的数学模型能较好的描述该降解过程 ,从而可以预测降解土壤生态系统中PAHs所需的时间、降解程度以及降解结束后被土壤所屏蔽的PAHs的量 ,数学模型在美国Alcoa公司LTU基地的大型土地生物处理工程中得到了验证。利用该数学模型 ,预测了 3,4,5和 6-环 -PAHs的土地生物处理过程及规律

| Abstract: | Biodegradation is an effective way to degrade organic chemicals in a soil water microbes system. In order to account for the recalcitrance of residual chemicals in soil, a new theory-organic chemical sequestration inside soil particles has been applied in this paper. A mathematical model, which is developed based on this theory, can predict the time and extent of PAHs biodegradation. The model simulation results match successfully with the field data of a bioremediation process in LTU site on Alcoa's Massena, New York. By using mathematical model, 3,4,5 and 6 ring PAHs biodegradation processes and regularities in remediation sites have been predicted in this paper. |
