Further, biological affine hydrophilic magnetic suspension filler contains the component of following parts by weight: 1 part of 90 parts of high density polyethylene(HDPE)s, 4 parts of gacs, 3 parts of Z 150PH, 4 parts of Z 250s, 2 parts of starch, 0.1 part of carbon black, 1.5 parts in paraffin, 1 part of chitin and aluminic acid lipoprotein coupling agent.
Gac is used to increase the filling surface roughness in the above-mentioned raw materials, increases surface-area; Z 250 is used to make the density of filler and water approaching, makes mikrobe accelerating growth simultaneously, thereby the effect of filler is greatly improved; Z 150PH is used to increase filler viscosity, improves its wetting ability; Starch is used to provide the nutrient of mikrobe early growth; Chitin is used to improve biological activity; The aluminic acid lipoprotein coupling agent is used to improve the flowability of raw material, simultaneously the each component of raw material is closely connected, and forms an integral body; Carbon black is used to increase the work-ing life of filler, and can improve the appearance luster of product.
Further, said biology is affine, and hydrophilic magnetic suspension filler is an open column shape, and its inner barrier partitions through " ten " font becomes four independently spaces.
The preparation method of this biology is affine hydrophilic magnetic suspension filler is following:
(1) with Z 250 and paraffin mixing;
(2) high density polyethylene(HDPE), gac, Z 150PH, carbon black, chitin and aluminic acid lipoprotein coupling agent being put into the mixer high speed stirs; The mixture that slowly adds Z 250 and paraffin; After treating that temperature is increased to 120 ℃; Stirring at low speed is cooled to 40 ℃, adds starch and stirs to room temperature;
(3) above-mentioned raw materials is dropped in the parallel double-screw extruder, melt extrude granulation;
(4) particle that will make drops in the screw extrusion press, extrusion molding.
As a kind of preferred, said grain diameter is 0.1～1cm.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) filler of the present invention has magnetic, helps stimulating microbic activity, after this filler is positioned over biological contact oxidation reactor, not only improves microbial reproduction and hangs film speed, and realized the application of magnetic effect technology in biological sewage treatment.It is 5～6 days that normal temperature is hung the film time down.Film upgrades fast, and particle diameter is about 100um～1mm; Improve mass transfer and oxygen transfer efficiency, suppressed the growth of a large amount of invalid assorted bacterium and anerobes, the high BOD5 volumetric loading of organic loading 6～12KgBOD5/ (m3d).
(2) wetting ability of filler of the present invention helps microorganic adhesion breeding metabolism, has reduced surplus sludge volume.
(3) suitable, the good hydrophilic property of filler proportion of the present invention, hanging the preceding proportion of film is 0.98～1.0g/cm
3, 1.01～1.10g/cm behind the extension film
3, hydrophilic angle α＜46 ° circulates under the aeration effect, and the utilization ratio of reaction efficiency and oxygen has effectively been improved at no dead angle.
(4) filler of the present invention has through-hole structure, and surface-area is big, and surface irregularity, has strong avidity with mikrobe, helps microorganism colonization, and mikrobe can reach 20～30g/l, and treatment effect is good, and no shorting region does not stop up, and does not reunite.
(5) raw material sources of the present invention are extensive, and manufacture craft is simple, and energy consumption is little, low preparation cost.
