MBBR filler is a new type of bioactive carrier used in sewage treatment

filler is a new type of bioactive carrier. It adopts a scientific formula. According to the different properties of sewage, it combines a variety of trace elements that are conducive to the rapid attachment and growth of microorganisms in polymer materials. It is modified and constructed through a special process. It has a specific It has the advantages of large surface area, good hydrophilicity, high biological activity, fast film hanging, good treatment effect, and long service life.
There are three main categories of R fillers
One is r filler, which mainly uses polyurethane sponge as the carrier and is mainly used for municipal sewage system renovation
The other is filler, and the biological carrier is mostly polyethylene material Made of Pall ring structure
The third type is r filler, which was developed by Bayer in Germany. By treating the r carrier surface, it adsorbs % activated carbon powder, making the r specific surface area as high as twice that of the first two. , BR is suitable for the treatment of high-concentration refractory organic matter and high ammonia nitrogen organic wastewater.
() Good geometric configuration
The outer membrane of the filler is updated quickly and has strong activity, the inner membrane is fully protected, and the microorganisms grow in good condition. It changes the external growth method of the traditional filler and makes the microorganisms degrade more efficiently.
The special structure allows air bubbles and pollutants in the water to freely pass through the interior of the filler, increasing the contact probability of the biofilm with oxygen and pollutants, greatly improving the mass transfer efficiency of the system and improving the biological degradation activity.
br> The biological flora inside the filler has a long life cycle and rich bacterial species, which is particularly suitable for the growth of nitrifying bacteria. It has both anaerobic and aerobic characteristics, and has obvious nitrification, denitrification and denitrification effects.
() The filler has a large specific surface area and a large amount of biological adhesion
The large enough carrier surface area is suitable for the adsorption and growth of microorganisms, with high effective biological concentration and strong processing capacity.
The higher biological concentration fully disperses and quickly reduces the fluctuations in incoming water quality, thereby improving the system's ability to withstand shock loads.
()Scientific formula makes the filler have good adhesion and is easier to fluidize.
The appropriate specific gravity (the specific gravity is close to that after the film is attached) enables the filler to be completely fluidized under slight stirring, minimizing energy consumption. The filler rotates freely and smoothly, and increases the impact and cutting of bubbles in the water. , crushing large bubbles and prolonging the residence time of bubbles in the water, the oxygen utilization rate can be increased by 10%, effectively reducing oxygen supply energy consumption.
The scientific formula makes it easier for microorganisms to attach to the filler, allowing microorganisms that are resistant to degrading and easily degradable organic matter to grow together, enriching the biological phase, and improving the treatment effect of refractory organic matter.
