Abstract:

This study applies PCR-DGGE fingerprinting technique to analysis the bacterial community structure of phosphorous removal and denitrification system. Through strains identification, it is found that acinetobacter sp.is the base of keeping favorable phosphorus removal effect, Spirochaeta sp.undertakes the function of organic matters removal, Bacillus sp. and Lampropedia hyalina sp.can propagate largely in the germiculture area(No.1 oxic tank), and can be preyed on by highlevel microbe(such as protozoa and metazoan) in protozoa growing area(No.2oxic tank) and metazoan growimg area(No.3 oxic tank). The predation between highlevel microbe and low grade microbe can promote efficient sludge reduction of HA-A/A-MCO process.
