Research progress of microbial analysis and microorganisms risk in biological activated carbon filter of drinking water treatment plant
The article systematically sorted out the microbial taxa and dominant species present on the sur-face of activated carbon,in which Bacteroidetes and Proteobacteria are often the dominant phyla among prokaryotes,and eukaryotes are dominated by protozoa and microscopic metazoans;and the potential functions of certain dominant phyla in the pollutant removal process are summarised,and most of them are aerobic chemoorganotrophic heterotrophic microorganisms.Possible risk microorganisms were also ex-plored,with the water-source chlorine-tolerant bacterial pathogens belonging to the Actinobacteridae,Ba-cilli and Gammaproteobacteria;and factors affecting the microbial community were summarised,including carriers,water quality,residual ozone,and influent water flow direction.The results are expected to pro-vide theoretical basis and technical support for the precise regulation of ozone/biological activated carbon filter in drinking water treatment plants.
