Technology Parameter  
 

 
Discriminant index        
 
1.  Adhesion of biofilm
Adhesion capacity of biofilm - the most important index to evaluate the quality of fillers: biological adhesion = protected surface area (connected with the design of fillers
running state
running state
Structure related) × bioadhesion per unit surface area (related to the performance of filler)
2.  Filler performance
Performance of packing - the most important index to evaluate the biological adhesion of packing
(1) Surface properties of fillers
1. Surface structure: it is generally considered that the surface roughness is large and the film hanging speed is fast.
2. Surface potential: generally, microorganisms are negatively charged, and the surface of filler is positively charged, which is suitable for microbial growth. 3. Hydrophilicity: the microorganism is hydrophilic particle, and the filler has good hydrophilicity and is suitable for microorganism growth.
Film hanging state
Film hanging state
(2) Hydraulic properties
1. Porosity: volume occupied by filler, high porosity.
2. Shape and size: affect the flow pattern of water and air flow.
(3) Fluidization performance: it is related to the density of filler. The density of the packing should be 0.97-1.03, and fluidization can be achieved with less aeration or agitation.
 
Application                     
 
1. The fluidized bed biofilm reactor can be used to remove organic matters and nitrogen. The flow bed biofilm reactor process can be used to remove conventional pollutants, even nitrogen and other nutrients in wastewater. The process has the advantages of simple equipment, flexible operation, saving land occupation, convenient operation, and can be used independently, in series or in parallel. It can be used for the purposes of nitrogen and phosphorus removal, high concentration wastewater removal and sewage treatment The new construction, reconstruction and expansion of the plant can increase the load, improve the treatment effect, reduce the floor area, etc;
2. Combined with the characteristics of biofilm process and activated sludge process in the same treatment unit, the activated sludge process with flotation packing can improve the capacity of BOD / COD removal and the function of phosphorus and nitrogen removal of the existing activated sludge process. This method is suitable for the transformation of the traditional activated sludge method. Without new structures, the function and efficiency of the system can be improved;
3. Applied to filtration of fish pond or high-purity Aquarium
 
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.
