Product Features
1. The effect of biological phosphorus removal is good. The
influent of anaerobic zone includes the mixture of total influent
and backflow from anoxic zone II, and the mixture at the end of
anoxic zone II. Due to the full denitrification and phosphorus
accumulation reaction, the concentration of nitrate is low. After
backflow to anaerobic zone, the anaerobic phosphorus release and
storage energy of phosphorus accumulating bacteria will not be
affected, so as to fully ensure the effect of biochemical
phosphorus removal;
2. The denitrification volume load is high. Different from the
traditional secondary treatment process, the sedimentation area is
set at the end of the process section. The sedimentation area of
the sewage treatment system of the invention is set in the middle
of the process section. The effluent is not the final effluent.
There is no need to worry that the sludge concentration entering
the sedimentation area is too high, resulting in the effluent SS
exceeding the standard. Therefore, the anoxic area can be allowed
to have high sludge concentration under the same sludge load The
volume load is higher;
3. It is widely used in the new construction, reconstruction and
integrated sewage treatment equipment of sewage plant.
Product Description
Biofilm reactors are divided into fixed bed and flow bed. In the
fixed bed, the biofilm carrier is fixed. In the traditional sewage
treatment system, the main technology is the fixed bed biofilm
technology. However, there are some problems in the traditional
fixed bed biofilm process, such as less effective contact between
microorganisms and sewage, easy blockage of filter material,
periodic back washing, and difficult replacement of fixed packing
and aeration equipment under packing. In recent years, the
performance and stability of MBBR have been improved continuously,
which has become an important technology of sewage treatment.
It not only integrates the advantages of activated sludge process
and biofilm process, but also overcomes the disadvantages of both.
It has the advantages of high processing capacity, low energy
consumption, no blockage, compact structure, no sludge reflux,
simple maintenance and management.
