Sponge factory, hydrophilic polyurethane (filter sponge) biological filler is a new type of biological filler synthesized from polymer materials. The macropores in the polyurethane filler are combined with micropores, and the macropores maintain good gas, liquid and solid contact conditions. , Micropores are used to immobilize microorganisms. The micropores have hydrophilic active groups such as amino groups, carboxyl groups, and epoxy groups, which can form ionic bonds or covalent bonds with some active groups in the microbial peptide chain. The microorganisms and biological enzymes are immobilized on the carrier.

Due to its structural characteristics, polyurethane fillers can mix and contact sewage, air and biofilms. Biofilms can not only sit in a large number of microbial carriers to maintain good activity and void variability, but also gas during operation. Driven by the three-dimensional flow of sewage, they collide with each other and are continuously cut into smaller bubbles by the microbial filler in a peristaltic state, which increases the utilization rate of oxygen and reduces the amount of aeration. Therefore, it has the characteristics of strong ability to cut bubbles, large space volume utilization rate and no dead zone. It is a replacement product of current biological fillers. It is widely used in domestic sewage treatment, petrochemical industry, light industry papermaking, food industry, winemaking, sugar making, printing and dyeing, tanning, pharmaceutical and other industrial wastewater treatment.
