Embodiment
Present invention is illustrated below in conjunction with embodiment.
The problem of in order to solve common biological biofilm time length, few biofilm amount and short filler service life, spy is directed to
How the raw material for making biologic packing material are improving the sides such as the service life of the biofilm speed of microorganism on filler and raising filler
Face expands research.
The present invention provides a kind of composite biological filler, includes the component of following mass ratio：
In the biological treatment process of sewage, the indispensable element that some metal ions grow as microorganism, bred, to micro-
Biological culture is most important.The application has found by specific research, when some metal ions are in appropriate concentration range, can
Accelerate the synthesis of cell, promote the process of biochemical reaction.
(1) calcium, as the composition cost for constituting microbial cell, is the indispensable nutrient of microorganism growth institute.Calcium
Salt participates in eucaryotic cell structure composition, and relevant with ability transfer, cell permeability regulatory function, and microorganism is larger to its demand.
(2) iron is cytochromes ferroprotoporphyrin and iron content redox element, is the basis of electron transmission again.Iron is that leaf is green
The necessary condition that element is formed, because the enzyme and iron-protoporphyrin of iron content play catalytic action in the biosynthesis of chlorophyll；While iron
Or the energy substance of some iron bacteria growths, therefore iron deficiency can make some metabolic activities in body reduce or lose, or make
Some iron bacteria growths cannot get energy, so that the growth of body is affected or stopped.
(3) magnesium is photosynthetic pigments --- the component of chlorophyll or bacteriochlorophyll for synthesizing photosynthetic microorganism, therefore
There is its important function in luminous energy conversion；Meanwhile, magnesium constitutes the active component of some enzymes；Other magnesium is some in microbial cell
Played an important role in the eucaryotic cell structure such as stabilization of ribosomes, cell membrane.Microorganism is different, they to magnesium the need for measure also not
Together.If lacking magnesium in environment, microorganism growth cannot get enough magnesium, and the stability of ribosomes and cell membrane can be caused to drop
It is low, and influence the normal growth of body.
(4) copper is a kind of metal activation agent, is the constituent of polyphenol oxidase, lactase and ascorbic acid oxidase.
Micro copper ion can as microorganism trace nutrient, this has key effect to constituting all kinds of special enzymes.
(5) cobalt is a kind of metal activation agent, is the constituent of vitamin B12, therefore makees with B12 all to contain in the enzyme of coenzyme
There is cobalt；Cobalt also take part in the symbiotic azotification of microorganism.
(6) nickel is the component of urase, hydrogenase, and can stimulate inorganization as the blue or green bacterium of algae, bead and methanogen etc
The growth of energy autotrophic bacterium, especially methanogen, nickel grows to it special significance.
The composite biological filler of the present invention, the environment of microbial growth is adapted to by creating, to improve microorganism
The speed of growth and treatment effeciency.
Present invention also offers a kind of preparation method of composite biological filler, comprise the following steps：
(1) mill：Metallic compound is milled into powder, particle diameter is less than 80 nanometers；Metallic compound includes calcium sulfate, dichloro
Change nickel, cobaltous sulfate, copper sulphate, iron chloride, magnesium sulfate；The consumption of each metallic compound is according to preset ratio determination and prepares, such as
Fruit uses the metallic compound containing the crystallization water, then each metallic compound aequum is calculated and counted according to the quality after dehydration
Calculate, and according to each metallic compound crystalline solid powder of PP consumption preparation respective quality.
(2) it is surface-treated：After being surface-treated using titanate coupling agent to metallic compound, titanate coupling agent
Consumption is the 1~4% of metallic compound content (mass fraction)；In this step, titanate coupling agent can respectively with each metal
Mixing is surface-treated compound in proportion respectively, after can also each metallic compound be mixed, according to metallic compound
Gross mass addition titanate coupling agent is surface-treated, it should be noted that should be ensured that titanate coupling agent is completely covered
Each metallic compound surface, to improve dispersiveness of each metallic compound in PP to greatest extent；Ensure that titanate esters are even simultaneously
Connection agent will not cause each metallic compound adhesion agglomerating, be uniformly dispersed in the base.
(3) it is uniformly dispersed：Metallic compound after surface treatment is mixed and disperseed with the polypropylene of molten condition
Uniformly, composite biological filler raw material is dried to obtain after cooling.For example, metallic compound and molten condition after surface treatment
After polypropylene is mixed and is uniformly dispersed, mixture is put into plasticizing on the twin screw extruder and extruded, extrudate is through water-carrying groove
After cooling, then process air-dry apparatus is tentatively dried up.Composite biological filler raw material is dried to obtain, can be direct if shape is suitable
Used as the filler in sewage disposal process, further across moulding mode is heated can also obtain needs as raw material
Profile.
In the present embodiment, the preset quality ratio of each component is as follows：
In addition, at present there are some shortcomings in major part biologic packing material：Surface is smooth, surface can be on low, strand without appointing
What moist group, surface hydrophobicity；The disadvantages mentioned above of filler causes biofilm speed slow.In this regard, by being carried out to filler material
It is modified, so as to change the surface roughness of filler and the content of surface polar groups, and then improve its biofilm speed and biofilm amount.
In another preferred embodiment of the present invention, also include on the basis of above-described embodiment, after step (3) as follows
Step：
(4) granulate：The composite biological filler raw material tentatively dried up cuts off by pelleter and granulates and dry；
(5) injection molded：Filler profile needed for granular composite biological filler raw material is molded by with injection machine, or
Filler fibre silk needed for being pulled into PP wire drawing machinees；
(6) chemical surface treatment：The filler of injection molded or the filament pulled into are subjected to chemical surface treatment, to change
The degree of roughness on filler surface and the content of surface polar groups, so as to improve the hydrophily of fiber surface；
(7) combine：The filler of different profiles is combined into preset shape, composite combinations thereof biologic packing material is formed, used
Biofilm production is carried out in sewage treatment project.
In another preferred embodiment of the present invention, on the basis of above-described embodiment, metallic compound is containing the crystallization water
Metallic compound drying and dewatering obtained by.Because the metallic compound containing the crystallization water is more easily obtained, therefore the present embodiment
The preparation method of composite biological filler can use the following raw material：
A. polypropylene (PP)；
B. calcium sulphate dihydrate (CaSO4·2H2O, 163 DEG C lose six crystallizations water)；
C. six it is hydrated Nickel Chloride (NiCl2·6H2O, 103 DEG C lose six crystallizations water)；
D. Cobalt monosulfate heptahydrate (CoSO4·7H2O, 420 DEG C lose seven crystallizations water)；
E. Salzburg vitriol (CuSO4·5H2O, is commonly called as blue stone, lapis divinus or blue vitriol, and four molecular crystalline water are lost at 190 DEG C
It is changed into CuSO4·H2O, 258 DEG C become anhydrous salt)；
F. ferric chloride hexahydrate (FeCl3·6H2O)；
G. bitter salt (MgSO4·7H2O, loses 6 crystallizations water at 150 DEG C, generate kieserite；200 DEG C lose
