Description
Technical field：
The present invention relates to bio-filter stuffing technical field, and in particular to a kind of tower biological filter 3 D elastic filler adds
Work modified plastic particles.
Background technology：
Tower biological filter is on the basis of biofilter, with reference to the packed tower mode in chemical industry, to have built straight
Footpath is with height than being 1:6-1:8, up to 8-24 meters of filter tank.Tower biological filter handles sewage also with aerobic microbiological
A kind of structures, are a kind of basic skills of biomembrance process processing sanitary sewage and organic industry sewage, at present in oil
Applied in terms of the sewage disposal of the industries such as work, coking, chemical fibre, papermaking, metallurgy.By in recent years practice have shown that, tower
Formula filter tank is preferable containing poison sewage effects such as cyanogen, phenol, nitrile, aldehyde to processing, and processing water outlet can meet the requirements.One it is because it has
Row advantage, is widely applied so having obtained comparing.
Filler is the important composition part of tower biological filter, and because tower body is high, if filtrate is very heavy, tower body must increase
Load-carrying members are reinforced, cost is not only added, and construction and installation are more complicated.For this problem, plastics are used at present
Type filler substitutes traditional coke, clinker, ceramics filling.
3 D elastic filler uses special wire drawing, strand system hair technique, anchors at corrosion resistant, high intensity by strand is interspersed
On axial cord, hard and soft appropriateness makes strand spatially evenly distributed radiation regimes.3 D elastic filler can be three-dimensional in effective coverage
Omnibearing even is unfolded, make gas and water, biomembrane obtain it is fully mixed ooze contact and exchange, biomembrane can not only equably implantation every
On a piece strand, good activity and space changeability are kept, and more and more big ratio surface can be obtained in the process of running
Product, and good metabolism can be carried out, it is that domestic other fillers at present are incomparable.Usually used 3 D elastic filler
Substantially all there is certain corrosion resistance, and specific surface area is big, but it is tight for wastewater treatment strand easily occur after for a period of time
The phenomenon deformed again, reduces its space changeability, so as to influence the treatment effect to waste water.
