Abstract

The invention discloses a fluidized bed biological filler. The filler is composed of the following components in percentage by weight: 75%-85% of polypropylene resin, 1%-3% of a coupling agent, 1%-2%of attapulgite, 3%-8% of a hydrophilic agent, 3-4% of diatomite, 1%-2% of magnetic materials, 1%-3% of antioxidants, 2%-6% of nutritional agents, 0.5%-2% of lubricating agents and 0.2%-1% of dispersing agents and has good biological adhesiveness. The invention further discloses a preparation method of the fluidized bed biological filler and a flowing composite active microbe biological bed adopting the fluidized bed biological filler.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a fluidized bed biological filler, a preparation method thereof, and a fluid composite active biological bacteria biological bed. Background technique [0002] Biological fluidized bed began to be used in sewage treatment in the 1970s. Materials such as sand, activated carbon, ceramsite, glass beads, porous balls, and porous polymers are used as the carrier of the biofilm. The biofilm is attached to the surface of the carrier. The waste water makes the carrier in the reactor in a fluidized state from bottom to top, increases the contact area between the biofilm and the pollutants in the bed per unit time, and is a structure for microbial adsorption and degradation or removal of pollutants. The definition of wastewater biological treatment is to use the life activities of microorganisms to absorb or absorb pollutants in wastewater as nutrients, transfer and transform poll...
