摘要/Abstract

摘要：

微生物共代谢是对污水中难降解性有机物生物降解的一种重要方式,共代谢过程中产生的非专一性关键酶可以促进难降解有机物的降解。大量的研究结果表明,选择合适的菌种和生长基质、控制生长基质和目标污染物的投加比、优化反应条件均可提高共代谢反应的处理效果。基于共代谢的作用机制,分析了影响共代谢的若干影响因子,旨在揭示共代谢对难降解有机物的降解机理。

关键词: 共代谢, 基质, 难降解有机物, 降解速率

Abstract:

Microbial co-metabolism is one of the important biodegration methods for microbial non-degradable organics in wastewater treatment.The non-specific key enzymes produced in the co-metabolism process can promote the degradation of refractory organics.A lot of research results show that the treatment efficiency of co-metabolism can be improved by choosing appropriate strain and growth substrate,controlling the adding ratio of growth substances and target pollutants,and optimizing reaction conditions.Based on the action mechanisms of co-metabolism,some influencing factors which affects co-metabolism are analyzed,so as to show the degradation mechanism of nondegradable organics by co-metabolism.

Key words: co-metabolism, substrate, non-degradable organics, degradation rate
