Description
Technical field
The invention belongs to technical field of polymer materials, and in particular to a kind of filled out by the spherical suspending that porous polymer is assembled
Material.
Background technology
In terms of sewage disposal, the method being currently mainly used is biological membrane processing method, its utilize the anaerobism of microorganism with
Aerobic effect is decomposing different pollutant in sewage.In this processing procedure, the culture and domestication of microorganism are most important
One link, wherein microorganism carrier-biologic packing material then play critical effect.The effect of biologic packing material is abundant profit
Effective unit volume is used, is expanded specific surface area supply micropopulation as much as possible and is more stayed in place.
Carrier filler currently used for Sewage Biological Treatment has soft/semi soft packing, elastic filler, combined stuffing etc.,
There are some technical deficiencies in them, maximum of which shortcoming is that specific surface area is relatively small, proportion is larger and easily
It is sticked together.The specific surface area of wherein elastic filler is less, and requires water distribution uniform air distribution, therefore needs mounting bracket, using compared with
Trouble.This kind of filler is replaced by the big HDPE porous annular packing of specific surface area and polyurethane biochemistry cotton packing gradually in the market
Generation.As patent CN203602396U discloses a kind of HDPE porous annular packing, the packing specific area is about 600～800m2/
m3, after its biofilm, density can assume fluidized state in the case of aeration in water, but its surface area is still inadequate slightly larger than 1
Greatly.
Emerging polyurethane biochemistry cotton packing on recent years market, its specific surface area are larger, and after water suction, wet density is omited
More than 1, fluidized state can be assumed in the case of aeration in water.But because polyurethane biochemistry cotton packing typically contains Carbimide.
Ester monomer, and use after needing explosion reaming, there are some unsafe factors in the course of processing and final products.
Content of the invention
It is an object of the invention to provide one kind assembles spherical suspending filling material by porous polymer, can be used for fluid bed degraded
Chemical oxygen consumption (COC) (COD) and ammonia nitrogen (NH3- N) filler.
A kind of spherical suspending filling material assembled by porous polymer, it is 1 by volume by porous polymer and filler to be：1
Mixture is filled in the inner chamber of spherical suspending thing and constitutes, and its density is 0.92～0.98g/cm3；The porous polymer and fill out
The volume sum of material accounts for the 20-80% of the cavity volume of spherical suspending thing.
Further scheme, described filler is particle diameter in the haydite of 3～12mm, starch, volcanic rock or zeolite.
Further scheme, the interior empty round that the spherical suspending thing is formed by injection molding by polyethylene or polypropylene.
Further scheme, the porous polymer is porous polypropylene that particle diameter is 3～10mm, expanded polystyrene or many
Hole polyurethane.
The present invention is adjusted close to 1 in the density of porous polymer and filler, and is mounted in spherical suspending thing
In chamber, have treatment effeciency high for fluid bed, the advantages of easy to use.The hydroaropic substance such as pottery powder, starch in filler so that
Spherical suspending filling material has hydrophilic, easy to be filmed.
The spherical suspending filling material of the present invention had advantages below for fluid bed：
1st, the density of spherical suspending filling material of the invention is 0.92～0.98g/cm3So as to can be suspended in fluid bed.Separately
Outward, as the specific area of spherical suspending filling material is big, hydrophilic easy to be filmed, long service life.
2nd, by spherical suspending filling material be used for process water factory's breeding wastewater, due to available surface area big, hydrophilic affine, this
The mass transfer and carrier surface forming biofilm property of filler is improve, so as to improve the clearance of ammonia nitrogen and COD.
The present invention provides a kind of spherical suspending filling material density of assembling and is slightly less than 1, big with specific surface area, hydrophilic affine,
The features such as fluidized state is good.Which is used for fluid bed, biofilm cycle is short, long service life, is a kind of easy to use, efficient, green
The filler of environmental protection.
