Abstract
The present invention relates to a stereogauze microbial carrier packing. It possesses gauze formed from alternative ribs which are uniformly distributed at its sides. Said invented packing possesses the advantages of planar gauze packing with uniform pore distribution, and its effective specific surface area is greatly raised as compared with planar gauze packing, so that it can prevent film adhesion to result in blockage, and can ensure uniform air distribution and water distribution, especially said packing possesses stronger multiple cutting action for air bubble, and its oxygen utilization ratio exceeds other packing in oxygen utilization ratio, and its effect is approaching to that of microporous aerator.
Description
The present invention relates to be used in the sewage biochemical processing process carrier that the set microorganism carries out oxidizing reaction.
The organic polluting water biochemical treatment needs to arrange in the oxidizing reaction pond and grows the microorganism carrier filler.Filler has rigid, soft, semi soft packing three classes by its proterties branch.Hard filler is eliminated substantially because of problems such as little, the easy obstruction of specific surface area, installation and transportation difficulties.Soft-filler mainly constitutes with fiber yarn, mounting block, advantage such as have that specific surface area is big, easy to be filmed, installation and transportation are convenient, but because fiber yarn is too soft, easily balling causes stopping up, and its effective ratio area is reduced rapidly.The existing certain rigidity of semi soft packing is difficult for balling to keep shape, and advantages such as specific surface is big, easy to be filmed, installation and transportation convenience are arranged again.Typical semi soft packing has plain net shape filler (as Fig. 1), elastic solid filler (as Fig. 2) etc.Generally speaking, except that the gauze packing of plane, fiber yarn of other filler (containing elastic solid filler) or converted top all are the radial radiation shape and distribute, close outer thin, the uneven drawback of void distribution in more or less existing.The centre portions of filler is because the silk bar is too intensive like this, though initial specific surface is bigger, biofilm also is easy to, but the easy conglomeration of microbial film, balling or knot post, effective ratio area reduces rapidly, and water distribution, cloth air exhaustion are inhomogeneous, result in blockage, the inner anoxic of cenobium influences decontamination effect improving simultaneously.Though plane gauze packing porous nickel, if pursue bigger specific surface area, pore design certainly will be got less, thereby the company's of generation film phenomenon and influence the homogeneity of gas distribution; If design areola bigger, though be difficult for the company's of generation film phenomenon, specific surface area is with restricted.
The present invention is intended to provide the stereo-net-shape microbial carrier filler of the big and porous nickel of a kind of effective ratio area, and is even to guarantee gas distribution, water distribution, prevents that microbial film from stopping up.
Stereo-net-shape microbial carrier filler of the present invention has the net of the porous nickel that staggered rib constitutes, at uniform many studs in side of net.
Stud is distributed in a side of net or is distributed in the both sides of net.
Stud can be upright muscle, also can be bent stud.
Solid netted filler of the present invention not only has netted stuffing hole crack, conventional plane density advantage of uniform, and because uniform many studs in side of net have the specific surface area more much bigger than plane gauze packing.Cause microbial film to stop up for fear of the company's of generation film phenomenon, solid netted filler gets the pore design of net comparatively sparse; But because the side of net has many studs, it is more than sufficient to remedy the specific surface area that loses because hole amplifies.Therefore its over-all properties is rather good.Especially this filler has stronger multiple cutting action to bubble, and coefficient of oxygen utilization surpasses other filler, and effect is close with micro-hole aerator.
Through simultaneous test: contact-oxidation pool is divided into three lattice, shooting property 3-D filler, plane gauze packing and filler of the present invention respectively, three lattice parallel runnings, flooding quantity is identical, and water quality is identical, and gas-water ratio is identical, boring aeration.Test-results is as follows:
One, sanitary sewage disposal (accompanying drawing 17)
Water inlet BOD
5About 150-200mg/l, oxidation pond total residence time 3 hours, water-gas ratio 1: 5.Experimental result shows, the stereo-net-shape microbial carrier filler film forming is even, after the biofilm, the rib chap of filler, the cylinder bar that the formation diameter is 3～5 centimetres, there is not latch up phenomenon, therefore the distribute water and air ability is strengthened, and dissolved oxygen improves, the biomembrane activity height, microbe population is many, and decontamination effect improving also just is better than other two kinds of fillers.
Two, little source of pollution water treatment (accompanying drawing 18)
About 3～the 5mg/1 of influent ammonia nitrogen, oxidation pond total residence time 1 hour, gas-water ratio 1: 1.Experimental result as can be seen, even under 1: 1 gas-water ratio, elastic solid filler does not have latch up phenomenon yet, but filler of the present invention does not still have latch up phenomenon, and its decontamination effect improving still is higher than other filler.

Embodiment is just like Fig. 3-9
Many staggered rib constitutes net 1, and the pore shape of net can be rectangle, circle, trilateral or Polygons, as Fig. 3-8.Each interstitial surface area is with 20-200mm
2For good.Uniform many studs 2 of one side of net 1, stud 2 is upright muscle.Porose 3 on the net 1, be convenient to a plurality of fillers serial connections are user mode shown in Figure 14 with rope.
Embodiment two is as Figure 10
Stud 2 is longer, makes it to swing inter-adhesive for preventing the water impact stud, has the stay 4 that is parallel to net 1 to support each stud 2, to keep the spacing of each stud 2.All the other are identical with embodiment one.
Embodiment three is as Figure 11
Uniform many studs 2 in the both sides of net 1, all the other are identical with embodiment one.
Embodiment four is as Figure 12
Stud 2 is the bent stud of meander-like.All the other are identical with embodiment one.
Embodiment five is as Figure 13
The uniform a plurality of upright muscle 2 of one side of net 1, the uniform bent stud 2 of opposite side.All the other are identical with embodiment one.Certainly the both sides of net 1 also can uniform a plurality of bent studs 2.
