Polyurethane filler

This product is a polymer synthesized hydrophilic polyurethane biological denitrification filler, which is formed by double explosion of oxygen and hydrogen, with a pore size of2～7mmInterconnected with each other to achieve a whole piece of packing bacterial carrier. Due to the special structure of this biological carrier, its breakthrough point is the realization of nitrite reaction on the outer surface of a single biological carrier in the aeration tank, and the denitrification of nitrite inside. There is simple physical adsorption, as well as the attraction of positive and negative charges, which make the surface of the carrier carry cationic active groups and hydrophilic groups such as hydroxyl groups. It can firmly bind with negatively charged microorganisms in sewage through bond and valence fixation, thereby firmly fixing microorganisms and biological enzymes on the carrier. After survival, microorganisms are not easily lost under the shear action of water and air. The load of microorganisms is large and the volume load is high, so that the ammonia nitrogen and total nitrogen in sewage can be simultaneously reduced. It also has strong ability to cut bubbles and spatial volume. Features such as high utilization rate and no dead zone, It is an updated product of microbial carriers in current biological treatment technology.

This biological carrier is suitable for nitrogen and phosphorus removal in sewage treatment projects such as high concentration organic wastewater, various industrial wastewater, refinery wastewater, daily chemical wastewater, pharmaceutical wastewater, and urban domestic sewage.
