微生物菌剂在难降解有机污染治理的研究进展

Recent research progress in microbial agents for treatment of refractory organic contaminants

摘要:

大量的难降解有机污染物被排放到环境中, 因其蓄积性、持久性和生物毒性, 对人类健康和生态环境造成严重危害。近年来, 利用微生物菌剂治理难降解有机污染物的研究已取得较好的进展。综述微生物菌剂在国内外的发展历程, 介绍微生物菌剂制备中常用的固定化技术及载体材料, 并分析总结微生物菌剂在酚类物质、多环芳烃和多氯联苯等有机污染物治理中的研究进展。在此基础上, 提出治理难降解有机污染物的微生物菌剂研发所存在的主要问题及其展望。

Abstract:

Refractory organic substances are widely released into environment, which causes adverse impact on human health and environment due to their bioaccumulation, persistence and biotoxicant. Recently, many microbial agents have been applied to treat the refractory organic contaminants. In this paper, we reviewed the developments of microbial agent in domestic and overseas, and described the microbial cell immobilizing technologies and the immobilized carries in the preparations of microbial agents. The application of micro-bial agents to the treatment of phenols, polycyclic aromatic hydrocarbons and polychlorinated biphenyls were summarized. In addition, the main problems, as well as the new perspectives, in this field were also discussed.
