Embodiment five
The inventive concept of the microbe carrier based on providing in the various embodiments described above, the utility model can also provide a kind of microbe stuffing carrier 5, (packing density in figure in filling carrier is less than the density of water as shown in figure 13, after being placed in water, filler is floating state, if packing density is greater than the density of water, filler piles up the bottom of carrier), this filling carrier comprises the described microbe carrier 52 in filler 51 and above-mentioned arbitrary embodiment, wherein, filler 51 is single filler or is mixed fillers, such as but not limited to adopting porous charcoal biologic packing material, one or more in high absorption ceramic packing or modified polyurethane foam filler etc., this filler 51 is filled in the cavity pocket of outer cover of carrier 52, in order to prevent filler 51, in carrier 52, scurry out, need to guarantee that the size of filler 51 is greater than the size in aperture on shell.In this filling carrier, the packing fraction of filler 51 is 30%-70%, be preferably 30%-50%, or be preferably 40%-60%, or be preferably 50%-70%, it can be according to different water quality and treatment process, select the filling ratio of different fillers 51, in Aerobic Pond, anaerobic pond or anoxic pond, add, to obtain corresponding processing power.
Especially, above-mentioned filler 51 has micropore, in this micropore, can form anaerobic environment, and suitable growth anerobe and double oxygen bacterium, can produce denitrification, realizes denitrogenation; The outside surface of filler 51 and carrier 51 can form aerobic environment, suitable growth aerobic bacteria, can remove organism, have nitrification and denitrification process in whole treating processes simultaneously, therefore filling carrier of the present utility model is applicable to multiple types, the existence of multifarious microorganism.
For character and the purposes of the filler described in clear and definite the utility model 51 more clearly, now take porous charcoal biologic packing material, high absorption ceramic packing and modified polyurethane foam filler and analyze as example, refer to following table:
The opening sack-like structure of the intensive porous that wherein, porous carbon biologic packing material has and bioactive ingredients are the bases of effectively removing COD and ammonia nitrogen, phosphorus, SS, turbidity, colourity and peculiar smell etc.Opening sack-like structure makes porous charcoal biologic packing material internal void structure flourishing, surface-area is large, and porosity is high, makes filler have strong adsorptivity, can improve the interception probability of suspended solids, its pollution substance of holding back also can be further used as the nutrition source of microorganism growth.Simultaneously, this structure is except making carrier surface provide aerobic microbiological bacterium perches, inside is more suitable for double oxygen bacterium and anerobe existence, form the stable ecosystem and food chain, be applicable to predominant bacteria and microorganism existence various, volume, the organism in waste water and total nitrogen removal are had to certain promoter action.For strengthening biological effect, also can in filler, add and increase bioactive ingredients, it can improve the wetting ability of filler, and porous charcoal biologic packing material has abundant carbon, as the extraordinary bacterium such as carbon biological bacteria are easy to biofilm and growth in filler, and make the active biomass that filler retention is higher.
High absorption ceramic packing, refer to according to the pore size of required height absorption ceramic packing, select the inorganic particulate ceramic base material of certain particle diameter to be uniformly mixed with appropriate organic binder bond, compression molding, drying, high temperature 1000-1300 ℃ sintering forms, forms the ceramic body filler of the opening sack-like structure with physics and chemistry good stability, careful porous, in this height absorption ceramic packing, has duct and the hole differing in size.In duct and hole, there is ion, this ion can with specific ion generation ion-exchange in water, as fluorion in water, or as the heavy metal ion of arsonium ion in water etc.; It can also with ammonia nitrogen, nitre nitrogen generation ion-exchange, make it to be concentrated in high absorption stupalith.This height absorption ceramic packing is due to the many micropores in surface, the surface irregularity that surface-area is large, material itself has and strongly hydrophilic, can make it be suitable for microorganic adhesion, form high-activity biological film, simultaneously can effectively catching suspended solids, suitable existence nitrifier and denitrifying bacteria in this height absorption ceramic packing hole not of uniform size, it can further remove ammonia nitrogen, the nitric nitrogen being enriched in material.The ion distributing in material hole has electric charge, thereby forms electric field around at ion, makes this height absorption ceramic packing have London force and electrostatic forcing, has strengthened its adsorptivity.
In addition, density, character and the filling mixture ratio of due to the utility model, inserting the filler 51 in carrier are different, can cause whole filling carrier density to change, therefore, the use-pattern of the filling carrier in the utility model also can be carried out different selections, as: can be suspended in water and use, can hang use, or fixedly use, etc.
It should be noted that, carrier 51 in microbe stuffing carrier in the utility model, owing to wherein having added dividing plate, can bring following benefit: (1) dividing plate is separated a plurality of fillers more uniformly and is laid in each cavity in spheroid, significantly moving of filler can be limited, and the space between filler can be increased, thus total specific surface area of increase carrier filler, microbial film quantity and concentration that filling surface adheres to are greatly increased, and then make the corresponding significantly lifting of water treatment efficiency; (2) can to prevent that filler local excessive from piling up the space cause narrow and small for dividing plate, the microbial film coming off blocks the situations such as the circulation of current and air-flow and occurs, therefore being provided with of dividing plate is beneficial to current and air-flow traverses to filling carrier inside, the perturbation action of air-flow and current can improve the contact probability of air-flow, microorganism and pollutent, improve coefficient of oxygen utilization, improve biochemical reaction efficiency, also can impel the aging microbial film on filling carrier to peel off decrement by flow shear, swing effect and air agitation effect, thereby back-purge system need not be set; (3) in being provided with the hollow casing of dividing plate, be equipped with in ceramic packing situation, dividing plate also plays certain prop carrier and fills out the effect of weight in water.
In a word, in actually operating, according to the difference of water quality, adjust the quantity of the internal cavities of carrier in above embodiment.That is, filling carrier is arranged to different structures.In conjunction with example, if need to there is a large amount of anerobes and/or double oxygen bacterium in water, now, can in carrier, add the second less porous plate, make the accumulation of filler comparatively dense, now, in water, environment is mainly anaerobic environment, is therefore applicable to the existence of anerobe and double oxygen bacterium; In like manner, if need to grow in water a large amount of aerobic bacterias in actually operating, need in carrier, increase the quantity of dividing plate, filler is separated fully, be beneficial to the gentle stream of current and enter into filling carrier inside, form aerobic environment, to reach, be applicable to a large amount of aerobic bacteria existence.
It should be noted that and the foregoing is only preferred embodiment of the present utility model, not thereby limit scope of patent protection of the present utility model, the utility model can also carry out equivalent improvement to the structure of above-mentioned various component.Therefore the equivalent structure that all utilizations specification sheets of the present utility model and diagramatic content are done changes, or directly or indirectly apply to other correlative technology fields and be all in like manner all included in the scope that the utility model is contained.
