Multi-phase flow dynamic membrane microbial carrier filler

Abstract

The invention discloses multi-phase flow dynamic membrane microbial carrier filler and belongs to the technical field of environmental protection and water treatment. The carrier filler with high-density polyethylene as a main material and calcium carbonate and starch as auxiliary materials adopts a thin-wall tubular structure, wherein reinforcing ribs forming 90-degree angles mutually and a plurality of inner rib plates are arranged in the thin-wall tubular structure, and spiral grooves are formed in the outer wall of the thin-wall tubular structure. The carrier filler solves the problem of incapability of positive rolling fluidization under the actions of hydraulic power, stirring, aeration and the like of conventional biological filler and makes up the defects of poor attaching force due to the smooth surface, poor hydrophobicity, small specific surface area and the like of the conventional filler. The filler with uniform small holes in the outer wall is in a suspended state in water and can vertically roll in a tank under the action of external force to have a sufficient contact reaction with the water; the carrier filler has a rough surface and is suitable for microbial membrane hanging; the filler has high flexibility, is suitable for a high-strength fluidization reaction and is made of a hydrophilic material, and the membrane hanging time is greatly shortened.

Description

technical field [0001] The invention relates to a multiphase flow dynamic film microbial carrier filler, which belongs to the technical fields of environmental protection and water treatment. technical background [0002] At present, in the water treatment process, biological carrier fillers are widely used. Most of the fillers have low strength, soft materials, smooth surfaces, and float in water. The formed microbial film cannot fully contact with water, even under the action of external force. Under normal circumstances, it cannot form an all-round "fluidization" state, that is, it cannot completely react with the water in the pool, which means that a lot of filler is actually added, but the effect is not very obvious. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a multiphase flow dynamic membrane microbial carrier filler, which should adopt a thin-walled tubular shape with uniform small holes ...

Problems solved by technology

[0002] At present, in the water treatment process, biological carrier fillers are widely used. Most of the fillers have low strength, soft materials, smooth surfaces, and float in water. The formed microbial film cannot fully contact with water, even under the action of external force. In this case, it cannot form a full range of "fluidization" state, that is, it cannot completely react with the water in the pool, which means that a lot of fillers are actually added, but the effect is not very obvious.
