| 中文摘要 |
| 多环芳烃 (PAHs) 是环境中普遍存在的一类典型有机污染物,绿色修复PAHs污染土壤已成为国内外环境和土壤界共同关注的热点问题之一.作为一种新型的微生物修复技术,固定化微生物修复有机污染土壤正受到越来越多的关注,国内外相关研究刚刚开始.本文重点评述了近几年国内外有关固定化微生物技术修复PAHs污染土壤的最新进展,总结了固定化微生物技术的修复原理、微生物固定化载体的选择、高效降解菌的筛选、固定化方法及影响因素等方面,并提出今后的发展方向,为我国开展固定化微生物技术修复有机污染土壤的研究提供参考. |
| 英文摘要 |
| Polycyclic aromatic hydrocarbons (PAHs), ubiquitous in the environment, are a typical organic pollutants. Green remediation of PAHs contaminated soil has become a hot research focus. As a novel microbial remediation technique, the immobilized microorganism technology (IMT) is attracting more and more attention to restore organic contaminated soil. This paper reviewed bioremediation of polycyclic aromatic hydrocarbons contaminated soil with immobilized microorganism technique. The IMT remediation principles, selection of the immobilized carries, screening of efficient PAHs-degradation microorganism, and methods of microorganism immobilized were summarized. The research trends and currently existing problems in IMT remediation of contaminated soil were prospected. |
