摘要
光能自养生物膜是一个由复杂微生物群落构成的相对稳定的微生态系统,微生物细胞及非生物物质镶嵌在微生物分泌的有机聚合物基质上,其显著特征是膜表面寄居着光能自养生长的微生物,并能在碳源缺乏条件下完成生物脱氮。总结了光能自养生物膜的形成机制,概述了光照、温度、微生物种类、营养物浓度对光能自养生物膜脱氮的影响,指出光能自养生物膜系统在富营养化水体和有机复合污染水源水的净化及碳源不足情况下的污水深度处理中具有广阔的应用前景。
Phototrophic biofilm is a relatively stable micro-ecosystem which consists of complex microbial synecology.Microbial cells and non-biological substances were embedded on the organic polymeric substrate which secreted by microorganisms.There are lots of photoautotrophic microorganisms exist on the surface of the biofilm,hence denitrification can still completed under the circumstance of lacking carbon source.In this paper,the formation mechanism and influencing factors of phototrophic biofilm are introduced,the application of phototrophic biofilm on purification of eutrophication source water and organic polymeric polluted source water are summarized.More research is necessary to develop the cost effective phototrophic biofilm for wastewater treatment under the conditions of lacking carbon source.
