Abstract：

In　order　to　investigate　the　influences　of　activated　sludge　aerobic　granulation　process　on　microbial　diversity　and　the　differences　of　microbial　community　structure　in　aerobic　granular　sludge　(AGS)　which　was　cultivated　by　different　carbon　sources　or　different　granulation　methods,　the　microbial　community　structure　of　seed　sludge　and　AGS　(AGS　with　artificial　wastewater,　AGS　with　real　domestic　wastewater　by　adding　diatomite　and　powered　activated　carbon　respectively)　were　analyzed　by　PCR-DGGE.　The　activated　sludge　aerobic　granulation　process　led　to　a　low　microbial　diversity.　The　bacteria　which　might　impact　the　stability　of　granular　sludge　were　eliminated.　However,　the　bacteria　which　were　capable　of　phosphorus　accumulation,　denitrification　or　bio-degradation　of　refractory　organic　substances　were　retained.　In　the　activated　sludge　aerobic　granulation　process　the　ammonia　oxidation　bacteria　(AOB)　were　enriched　to　a　certain　extent.　Compared　with　the　seed　activated　sludge,　the　diversity　index　and　evenness　index　of　AOB　were　increased.　The　dominant　bacterial　communities　in　AGS　were　Proteobacteria,　Bacteroidetes　and　uncultured　bacterium.　The　dominant　AOB　in　AGS　were　all　belonged　to　Nitrosomonas.　©　2016,　Chinese　Society　for　Environmental　Sciences.　All　right　reserved.
