静止或缓流污染地表水微生物固定化修复技术研究进展

污染地表水体修复问题是最近几年才被广泛关注的环境保护课题,由于污染地表水体的特殊性,常规修复方法难以发挥高效作用,固定化微生物可以通过提供特殊的微环境,较好地保护优势菌不受土著菌恶性竞争,在保持高效修复能力的同时,可以将优势菌屏蔽于恶劣环境之外,在一定程度上克服了传统修复工艺的不足,具有较好的应用前景.本文概述了微生物固定化技术的特点,分析了利用固定化微生物修复污染环境介质存在的问题和可行性,针对城市静止或缓流污染地表水的特征,指出了将微生物固定化技术移植到污染地表水体修复领域需要解决的的关键技术.

Review on bioremediation of immobile or slow surface waters with immobilized microbe techniques

The remediation of contaminated surface water is a widely concerned environmental topic in recent years.Sometimes the conventional techniques cannot work effectively restricted by the waters' particularities.The technique of immobilized microbe,abbreviated IM,is becoming an important remediation method because of its significant advantages.It can not only provide a special microenvironment to protect dominant microbe from malignant competition of aboriginal microbe,but shield microbe from the environment.Base on the analysis of IM technical characteristics and its feasibility,some key techniques to be solved were put forward to remediate immobile or slow-flow urban surface waters with IM.
