The invention provides a method for evaluating
organic matter degradation potential of a
biological filter material, and relates to the field of drinking
water treatment. The method comprises the following steps: establishing a
reference database of microbial degradation target organic matters; carrying out
DNA extraction on the
biological filter material sample and obtaining metagenome
sequencing data; sequentially carrying out
genome assembly and binning, screening and redundancy removal on the metagenome
sequencing data to obtain a non-redundant MAGs set; and performing species
annotation, calculating microbial abundance, comparing a non-redundant MAGs set with the established
database, determining MAGs containing degrading genes and / or degrading enzymes, obtaining the corresponding microbial abundance, and evaluating the potential of the
biological filter material for degrading organic matters by using the obtained microbial abundance. According to the method, only metagenome sequencing and analysis are carried out on the
filter material sample, organic matters do not need to be put into the filter for operation, the organic matters or degradation intermediate products do not need to be detected, the
evaluation period is short, the operation is simple and convenient, and the environmental
pollution is reduced.
