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.
Application advantages
1. Fast start-up, short transformation and commissioning period;
2. Large biomass, strong resistance to impact load;
3. Save energy, land and investment;
4. It can be applied flexibly in aerobic, anoxic and anaerobic
sections;
5. It is directly added without new structures:
6. It is especially suitable for the upgrading of wastewater
treatment plant and the deep denitrification treatment;
7. The technology is also used in the construction of integrated
equipment, which can effectively save 1 / 3-1 / 2 of the floor area
compared with the conventional process, and the management is also
simpler.
