The utility model compared with prior art has the following advantages:
(1) filler center rigid macromolecule skeleton has higher physical strength, even packing height is high again, filler also is difficult for being compacted; Flexible all around bio-carrier porous medium has very strong flexible ductility, can make between filler and the filler and filler and bio-trickling wall between sufficient contact that keep, reduce to fill voidage.
(2) in filler rigid macromolecule skeleton, added nutritive substance, between filler biofilm and gas pollutant degradative phase, microporosity by filler macromolecular scaffold inside discharges and diffuses to the skeleton surface slowly, the microorganism that is attached absorbs, replenish nutrition with the balance microorganism, participate in microbial metabolism, promote the degraded of biomembranous formation and gas pollutant, effectively avoid problems such as bad and biofilm cycle of the microbial nutrition that causes less than the filler center owing to nutritive medium spray is long.
(3) added porous slowly-releasing controlled substance such as diatomite or gac in filler rigid macromolecule skeleton, these materials provide good passage for the slow release of nutritive ingredient, have promoted the growth metabolism of microorganism at filling surface.Simultaneously, the roughness and the specific surface area of filling surface have been increased, for microorganism provides more apposition growth point, improved the biofilm amount on biofilm speed and the unit surface, and can improve microorganism active greatly, improved the defective of the smooth not easy to be filmed of original polymer surface, thereby improved the removal efficient of bio-trickling filter foul gas.
(4) slowly-releasing of nutritive substance in the filler rigid macromolecule skeleton, rigid macromolecule skeleton inside and surperficial pre-existent pore are further strengthened, specific surface area and porosity have been increased, and promoted microorganism adhere to biofilm and growth metabolism, improve microorganism active greatly, thereby improved the processing efficiency of foul gas.
(5) because the slow releasing function of nutritive substance in the filler rigid macromolecule skeleton, make the apposition growth and the activity thereof of packing microbial reduced greatly by the influence of the feed rate of bio-trickling filter recirculating nutrient solution, avoided owing to adding the slow or active situation about descending of the not enough bio-trickling filter microorganism colonization that causes of nutritive substance.
(6) raw material sources that the utility model adopted are extensive, and manufacturing procedure is convenient and simple, and production cost is low and effective.
