Fluidized Bed Packing (MBBR) 流化床填料（MBBR）

   Fluidized packing, also known as MBBR packing aerobic biological fluidized bed process, adopts three-dimensional hollow packing as aerobic biological carrier, the packing is hollow structure, and the packing is suspended in water during normal operation. Anaerobic bacteria grow inside the filler to produce denitrification to remove nitrogen; aerobic bacteria grow outside to remove organic matter, and nitrification and denitrification exist in the entire treatment process.

1. Using high-quality copolymer materials, soaking in wastewater for a long time will not degrade, nor will it be toxic to microorganisms, which is better than using other materials such as polyvinyl chloride.

2 Special structure, the hollow packing structure is a total of three layers of hollow circles inside and outside, each circle has 1 edge and 36 edges outside.

3 High specific surface area, the specific surface area of ordinary microorganisms is 90-180, the specific surface area of hollow fillers can reach 600, and the double specific area is as high as 860 or more. Due to the high specific surface area, the biomass per unit volume is high, which can achieve hydraulic power. The purpose of a short stay.

4 High activity of microorganisms. The microbial film that grows on the surface of the filler collides due to the fluidization of the filler. The aeration and scouring make the microorganisms in the logarithmic growth period of high activity, and the treatment efficiency is high.

5. The hollow packing is floating type, which is easy to replace and has a long service life.

6. Strong ability to denitrify and decompose organic matter to achieve the purpose of removing ammonia nitrogen. Specifications and models of fluidized bed packing: Category Model Specifications φ25mm Length 10~12mm Thickness Circumference 0.6~0.8mm Middle circle 0.4~0.5mm The outer periphery is toothed, there are three layers of circles from the center to the outer circle, the out-of-round rate is ≤20%, the tooth depth ≮1mm Material polypropylene
