Function of biological filler

        Biological fillers are divided into combined fillers, three-dimensional elastic fillers, porous suspended ball fillers, active biological fillers, etc

        In the aerobic biological fluidized bed process, the three-dimensional hollow filler is used as the aerobic biological carrier, and the filler is a hollow structure, which is in normal operation, and the filler is suspended in water. Anaerobic bacteria grow inside the filler to produce denitrification, which can remove nitrogen; Aerobic bacteria grow outside to remove organic matter. There are nitrification and denitrification processes in the whole treatment process.

        With the application of biological treatment technology in industrial wastewater treatment becoming more and more mature, biological fillers are widely used at this stage. Biological filler is an essential thing in the biochemical tank. The question is, what role does it play? Today, LATINO will discuss with you. 

       Why put biological filler? At the initial stage of wastewater treatment and commissioning, the wastewater has impact on microorganisms, and the water itself has fluidity. In this way, the microorganisms that originally gathered and grew will be impacted and dispersed to every corner of the pool. However, the growth of microorganisms is to divide from a single cell into multiple cells, and then gradually form a colony visible to the naked eye. The impacted microorganisms are distributed around the pool, but through the role of the filler, the microorganisms adhere to the filler for growth. In this way, after long-term operation, each microbial population will find an area suitable for their own growth, which will form a stratification phenomenon.

        Another point is that the selected material of the biological filler produced by retenol is organic and inorganic composite, which is more suitable for the attachment of specific bacteria. It has the advantages of large specific surface area, large amount of film, corrosion resistance and long service life, and can meet different uses and needs.
