Heavy metal pollution has become a global environmental problem due to the strong toxicity, high bio-enrichment and non-degradation of heavy metals. Among different heavy metal pollution treatment technologies, microbial biofilm-based remediation technology has been widely used in the prevention, control and remediation aspects due to the advantages of high efficiency, low cost and high sustainability, and this technlogy has become an emerging research hotspot. In order to further uncover the relationship between microbial biofilms and heavy metals, this article systematically investigated the literature on the adsorption of heavy metals by microbial biofilms in the past two decades. And the adsorption mechanism, adsorption related mathematical models and effects of pH on microbial biofilms were also elaborated. In particular, the importance of pH that is identified as a factor affecting the treatment effect of the microbial biofilm technology was highlighted and systematically elaborated. This review will provide scientific suggestions and supports for future research on microbial biofilm based heavy metal removals. |
