It is to hold attached microbial that the master of filler in biofilm reactor plays effect, that carrying of microorganism growth stopped, for microorganism provides the stable environment of perching and breeding, its abundant internal surface, for microorganism provides surface and the internal space of adhering to, makes reactor keep as far as possible more microbial biomass.In general packing specific area is larger, and the microbial biomass adhering to is more, and the organic loading that can bear is also relatively high.Filler is the place that in reactor, microbial film contacts with waste water, and current are had to enforceable turbulent fluctuation effect, and current can be redistributed, and changes its flow direction, thereby it is more even to make current foretell distribution in reactor cross-section.Meanwhile, current mix in the inner cross flow that forms of filler, for contacting of waste water and organism created good hydraulics.And filler has repetition cutting action to the bubble in aerobic reactor, the dissolved oxygen concentration in water is improved, thereby the mass-transfer filler of having strengthened between microorganism, organism and dissolved oxygen three have certain crown_interception to the suspended substance in water.Owing to there being filler to exist in reactor, the concentration of suspended substance in water outlet is greatly reduced, filler is by the factors such as the interception of suspended substance in sewage, precipitation, inertia, diffusion, water power are realized to the crown_interception of suspended substance.
Filler shape has honeycomb tubulose, pencil, corrugated, circular radial, peltate, netted, tubular, rule granular and irregular granular etc., and the material of effect substantially all adopts glass reinforced plastic, polyvinyl chloride, polypropylene, vinylon etc. except particulate filler.Particulate filler is to occur the earliest but the present filler of still continuing to use; material is inorganic haydite or quartz sand; fibrous nodules filler etc., the ability that the principal feature of this class filler is surface irregularity, be easy to settled organism, hold back suspended contaminant is strong, shortcoming be resistance large, be easy to stop up.Irregular protruded packing is conventional Ha Kaideng and polyhedron empty ball etc., and useful ceramics, graphite silicon carbide, plastics or metal are made, simple in structure, cheap, but fluid distribution is uneven.Material cellular or corrugated plate shape filler is generally glass reinforced plastic or plastic pipe chute filler (polyethylene, polystyrene, polypropylene etc.), its main advantage be simple in structure, porosity is high, light weight but intensity is high, good, the old and feeble biology of antiseptic property is easy to come off etc., shortcoming is that the biological growth at filling surface is wayward with the balance that comes off, and is difficult to obtain the flow velocity of homogeneous in filler.
The filler of domestic main employing is at present plastics or frp honeycomb filler, three-dimensional wavy filler, soft cellulose filler, semi soft packing, plastics or frp honeycomb filler, smooth surface, microbial film adheres to rate variance, easily aging and often easily produce in actual use filler and stop up.Flow-shape in soft-filler is undesirable, easily by microbial film cat knot together, produces balling phenomenon, and its effective surface area is greatly reduced, and then produces anaerobism phenomenon in the inside of balling, affects treatment effect.
Chinese patent literature CN101696053A discloses a kind of < < three-dimensional natural fiber spherical biofilm packing > >, this filler comprises wood frame and bamboo matter biofilm packing monomer, described bamboo matter biofilm packing monomer is the hollow ball shape of bamboo chip braiding, layer series is fixed in wood frame, and bamboo matter biofilm packing monomer leaves space between any two.This packing specific area is large, should not stop up, and adopts natural material, cheap, corrosion-resistant.CN201713381U discloses < < biofilm process suspended carrier ball > > for sewage disposal, this floating stuffing ball is one-time formed whole spheroid, it is with the molectron in fan-shaped cavity, specific surface area is large, and treatment effect is better.But these two kinds of fillers are because filling ball spherome surface is smooth, and centre of sphere segment space is little, is unfavorable for biomembranous formation, be mainly that microbial film can not get upgrading in time, limited the diffusion of water pollutant to spheroid inside, affect biological treatment effect.
