摘　　要：就污水生物处理过程中微生物次级代谢产物的生成特性及其影响的研究进行了综述。溶解性微生物产物和胞外聚合物是污水生物处理工艺过程中微生物次级代谢的主要产物,其相对分子质量分布、生物可降解性、螯合性、毒性等能说明生物处理系统的整体运行状况;而进水浓度、SRT、HRT、OLR(有机负荷率)等系统运行参数也影响微生物次级代谢产物的生成与性质。目前,有关污水生物处理中微生物次级代谢产物的研究还很不完善,很多问题有待进一步研究。A review concerning the production,characterization and implications of microbial secondary metabolites in biological wastewater treatment is presented in this paper.SMP and EPS are the main productions of microbial secondary metabolism in biological wastewater treatment. This review outlines some important discoveries with regard to the MW distribution,biodegradabili- ty,chelating properties,toxicity,which imply the whole conditions of the treatment progress.It al- so summarises the effect of parameters on their production.However,the knowledge regarding mi- crobial secondary metabolites in biological wastewater treatment is far from complete.Much more work is still required to be done.
