Abstract—Immersed biofiler was applied to purify the river provides vectors for bacteria, especially the nitrifying bacteria
water by increasing of anism quantity in the system. In with long generation time, and position of pollutants
order to analysis the water purification process, the denaturing could be promoted by reducing the loss of effective bacteria.
gradient gel electrophoresis (DGGE) and real-time PCR
Study on munity in biofilter system is one of
technology were used to analysis the munity and
the most significant work, for it is important indicator to
the superior strains of the system. DGGE pattern showed that
evaluate the effect of the biofilter system [2, 3]. With the
there has been a munity structure on the 14th day (Z1)
development of molecular biological methods, new
and single munity in March (Z5) in enormous
technologies and equipment has provided powerful assistance
