product description
the moving bed biofilm reactor (mbbr for short) is a new and highly efficient
biofilm reactor developed in recent years based on the biological contact
oxidation process and activated sludge process. it is characterized by its
strong load-bearing capacity, high treatment efficiency, long sludge age, small
amount of excess sludge, good effect of denitrification and phosphorous removal,
non-sludge bulking, etc.
the core component of the mbbr process—the
suspended filler should have the following characteristics: the large specific
surface area to increase the biomass; adaptation to the biofilm growth and short
film-forming period; appropriate water vapor paths favorable for film formation
and stripping; the specific gravity after film formation close to water and apt
to fluidization; long service life, etc.
yulong activated biological
filler (yl-i, yl-ii and yl-iii) is a new activated biological carrier, which
adopts the scientific formula and integrate various microelements favorable for
microorganisms’ apposition growth into high polymer materials according to the
different adaptabilities of biotic populations. it is made after being modified
and structured by special processes.
its advantages: good hydrophilicity
and quick film formation, large specific surface area and high biomass,
appropriate specific gravity and good fluidization effect, high oxygen
utilization efficiency and long service life.
application range:
standard and quantity enhancement of sewage upgrading
and reconstruction
processes of the sewage treatment fluidized bed and
biological filter
biological treatment of reclaimed water reuse
denitrification and phosphorous removal for river regulation
ammonia
nitrogen removal and water purification for aquaculture
biological filler
for biological deodorization towers
applicable industries: municipal
affairs, electric power, pharmacy, chemical industry, electroplating,
metallurgy, medical treatment, machinery, paper making, printing and dyeing,
food processing, aquaculture, etc. with the continuous improvement of products
and deepening of application, yulong activated biological filler will be applied
more and more extensively.
judgment of film-forming maturity
visual judgment:
the biofilm
distributes on the surface of the carrier evenly; it is more compact when it is
nearer to the surface of the carrier; otherwise, it is looser. meanwhile, the
color of the carrier becomes dark. these mark that the film formation of the
carrier enters the mature phase.
judgment by microscopic
examination:
the biofilm’s structure is compact and the variety of
microorganisms is diversified. there are many sessile ciliates, vorticella,
epistylidae, etc. there is a small amount of rotifers and swimming ciliates.
these mark the maturity of the biofilm.
