MBBR filler is a microbial carrier used in MBBR process, mainly for microorganism to provide suitable environment for growth.

 

MBBR packing is a new kind of biological active carrier. It adopts scientific formula. According to the different properties of sewage, it combines many kinds of microelements which are beneficial to the rapid adhesion and growth of microorganism. After special process modification and construction, it has a large specific surface area, good water affinity, high biological activity, fast film hanging, and the place of rapid growth. It has many advantages, such as good effect and long service life.

 

The core of MBBR technology is biological carrier and operation control technology.

 

Biological carriers are products closely integrated with material science and biology.

 

Biological carriers are dominant biological selectors, especially in refractory wastewater.

 

Discriminant index of MBBR packing

 

 

1. Adhesion of biofilm

 

The adhesion capacity of biofilm - the most important indicator of the quality of the packing: the amount of biological attachment = the protected surface area (related to the design structure of the packing) * the amount of biological attachment (related to the performance of the packing) per unit surface area.

 

Two, packing performance

 

Filler performance -- the most important index for evaluating the biological adhesion of fillers

 

(1) surface properties of packing

 

1. Surface construction: it is generally considered that the surface roughness is large and the film speed is fast.

 

2. Surface potential: the general microorganism is negatively charged, and the surface of the packing is a positive charge, which is suitable for microorganism growth. 3. Hydrophilicity: microorganism is hydrophilic particle, filler is hydrophilic and suitable for microorganism growth.

 

 

Application advantages:

 

 

Quick start, short period of transformation and deb ing;

 

Large biomass, strong resistance to impact load;

 

Saving energy, saving land and saving investment.

 

Flexible application, aerobic, anoxic and anaerobic stages.

 

Direct addition does not require additional structures:

 

It is especially suitable for upgrading and deep denitrification in sewage treatment plants. [1]

 

The technology is also used in the construction of integrated equipment, which can effectively save the 1/3-1/2 area and the management is simpler than the conventional process.
