Description
Technical field
The present invention relates to a kind of efficient hydrophilic biologic packing material for sewage disposal and device, belong to sewage disposal and water
Body recovery technique field.
Background technology
Biomembrance process is that the microorganism (i.e. biomembrane) in filler surface carries out organic sewage process using apposition growth
Method.The life that biomembrane is made up of the aerobic bacteria of highly dense, anaerobe, amphimicrobe, funguses, protozoacide and algae etc.
State system.Filler is biomembranous carrier, and its effect is the surface providing attached growth of microorganisms.Needed for growth of microorganism its
In the case of his condition is suitable, the contact that effective biomembrane is more and microorganism is with pollutant of growth in unit volume filler
Area is bigger, then wastewater treatment efficiency is better, and the performance of therefore filler determines the effect of sewage disposal.
Excellent filler should have good hydrophilic, larger specific surface area and rough surface, shape and porosity
Properly, high mechanical strength, good hydraulics and biologically inert is good, lighter weight the features such as.Common filler can be divided into no
Machine filler and organic polymer filler.Inorganic filler is such as：Haydite, granule/Powdered Activated Carbon etc. due to hydrophilic and rough surface, because
This biofilm is good.But because these filler proportions are larger, can deposit buildup, therefore hydraulics are very poor, be unfavorable for microorganism with
The contact of organic pollution and degraded.Contrary organic polymer filler (material mostly is polyethylene, polypropylene and polyester) is easy to
Fix or suspend in water, there are good hydraulics, but these materials are hydrophobicity, and smooth surface, it is accordingly difficult to
Attached, the particularly primary biomembranous attachment of biomembranous extension.Conventional organic filler is divided into bulk, tubulose, threadiness by shape
Deng three major types.The overwhelming majority using there being support bracket fastened installation form, fix by filler position in water；Also have using no fixing
The form that frame, filler freely suspend in water, filler position in water is not fixed.In existing bio membrane process, filler
Using there is problems with：
(1) filler is hydrophobicity it is difficult to biofilm；
(2) biomembrane adhesion amount is little, poor processing effect；
(3) degraded of the growth to microorganism and pollutant does not have facilitation.
Content of the invention
The invention discloses a kind of efficient hydrophilic biologic packing material for sewage disposal and device, can be used for biomembrance process
Process sewage and water remediation, it has, and hydrophilic is strong, specific surface area is big, biofilm speed is fast, biofilm amount is high and difficult for drop-off,
Improve microbial activity, easy for installation the advantages of.
The technical solution used in the present invention is as follows：
A kind of efficient hydrophilic biologic packing material for sewage disposal, including filler it is characterised in that in described filler
Surface cure modified activated carbon, is impregnated with trace metal catalysts in described modified activated carbon.
Described filler is elastic filler.
Described elastic filler is polypropylene filaments, and diameter is in 0.3-0.7mm.
Described trace metal catalysts are to promote one of minor metallic element Fe or Co or Ni of growth of microorganism.
A kind of efficient hydrophilic bio-packing apparatus for sewage disposal, including framework, fixing axle, cellosilk, described
Fixing axle be fixed on described framework, it is in hairbrush shape that described cellosilk is from top to bottom fixed in described fixing axle,
The cured modified activated carbon of described filament surface, is impregnated with trace metal catalysts in described modified activated carbon.
Described framework is in cubic shaped, and is correspondingly provided with the crossbeam of fixing described fixing axle at top and bottom,
Described crossbeam is parallel to a line of described framework；Described fixing axle is parallel, be vertically arranged and be uniformly fixed in described framework,
Described fixing axle two ends are fixed on described crossbeam.
Described framework is made up of rustless steel or plastic material.
Described trace metal catalysts are to promote one of minor metallic element Fe or Co or Ni of growth of microorganism.
Described cellosilk is polypropylene filaments, and diameter is in 0.3-0.7mm.
The rope-like constructed that described fixing shaft material is made for polyethylene from high pressure process, during described cellosilk with fixing axle is
The heart, layered and parallel be wrapped in this fixing axle, overall is in hairbrush shape；Described modified activated carbon is uniformly fixed on using binding agent
On cellosilk, and guarantee that the active site of activated carbon is not wrapped up by binding agent.
Beneficial effect：
The activated carbon coating on filler surface enhances hydrophilic, and most of microorganism has good hydrophilic in itself, fills out
Material surface can form hydrogen bond structure with microorganism；The activated carbon surface free energy of filler is less than the surface of hydrophobic filler simultaneously
Free energy, the microorganism in water is easier access to the growth of hydrophilic filler surface adsorption.In addition, the activated carbon of solidification improves and fills out
The specific surface area of material and roughness, improve filler to the capturing ability of microorganism it is easy to microorganism colonization and biomembrane jail
Soundness is high.Therefore, larger specific surface area, higher surface roughness can make biomembranous formation speed accelerate.Rough surface
Than smooth surface, there is thicker laminar boundary layer, being provided that good Static Water mechanical environment thus avoiding flow shear pair
The adverse effect that attached microbial increases, also makes the pollutant in sewage gather in filler near surface simultaneously, enhances micro- life
Mass transfer between thing and pollutant, improves contaminant degradation response speed.
Additionally, filler surface secures the trace metal catalysts needed for growth of microorganism by activated carbon infusion process, urge
Change efficiency high, selectivity are strong, stability is strong, have further speeded up the degraded of microbe.
New and effective hydrophilic biologic packing material hydrophilic is strong, specific surface area is big for this, curing catalysts in filler, biofilm are fast,
Not easy to knot groups, can increase substantially micro organism quantity in biochemistry pool, strengthen capacity of resisting impact load, improve the removal effect of pollutant
Rate, anti-hydraulic blow, and convenient to install and maintain.

Embodiment 3
The preparation method of the present invention：
First, traditionally pp material is put into injection machine, heating polypropylene fusing, is drawn wire by mould,
Make cellosilk 5 after cold water cooling, diameter is chopped into 10cm specification in 0.5mm, then length.
Fixing axle 4 material is polyethylene from high pressure process, makes rope-like constructed.By cellosilk 5 centered on fixing axle 4, layering is flat
Row is wrapped in fixing axle 4, and overall is in hairbrush shape.
Traditionally activated carbon is put into the liquid that the weight percent concentration containing metallic catalyst Fe is 5-10%
Middle dipping, metallic catalyst is gradually adsorbed in activated carbon surface, after dipping balance, activated carbon granule is isolated from liquid
Come, then activated carbon is dried, roasting, activation etc., you can prepared modified activated carbon 6.
Modified activated carbon 6 is uniformly fixed on cellosilk 5 with binding agent, on cellosilk 5, modified activated carbon density is
0.35g/cm3, through test, using mesh number, activated carbon density on the granular active carbon guarantee filler of 10-24 mesh is high, simultaneously
Do not wrapped up by binding agent, and also ensure that the active site of modified activated carbon 6 is not wrapped up by binding agent, binding agent selects PVC2021
Binding agent+oxolane, makes the biologic packing material 7 of the present invention.
Then fixing axle 4 is fixed on framework up and down on corresponding crossbeam by framework 2 material selection rustless steel or plastics.
Following table is the performance comparison data with ordinary elasticity filler for the biologic packing material of the embodiment of the present invention 3 preparation, further
Effect of the present invention is described.
Prior art ordinary elasticity filler develops on the basis of soft-filler and semi soft packing and forms, and it has concurrently
