Description
Technical field：
The present invention relates to tower biological filter packing technique field, and in particular to a kind of tower biological filter builds and uses paper wasp
Nest filtrate.
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 is also with aerobic microbiological treatment sewage
A kind of structures, are a kind of basic skills of biomembrance process treatment sanitary sewage and organic industry sewage, at present in oil
The sewage disposal aspect of the industries such as work, coking, chemical fibre, papermaking, metallurgy is applied.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 treatment, processes out water energy and meets the requirements.Because it is with one
Row advantage, so obtained comparing be widely applied.
Filtrate 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 increased, and construction and installation are more complicated.For this problem, lightweight has been used at present
Filtrate substitutes traditional coke, slag, ceramic grain filter.
Paper honeycomb filtrate is one of light filter material conventional at present, and with larger surface area, even structure is conducive to sky
The distribution of gas, and proportion is lighter, unlikely increase tower body burden.Vertical honeycomb is conducive to the excretion of the biomembrane for peeling off,
And because honeycomb surface is rougher, biomembrane easily adheres to, and biomembrane can be quickly formed in cultivation stage.But sewage from upper and
During lower flowing, easily trigger gross distortion under souring, cause internal voids to block, so as to influence sewage treating efficiency.
The content of the invention：
The technical problems to be solved by the invention are to provide a kind of strong scour resistance, high treating effect and long service life
Tower biological filter build use paper honeycomb filtrate.
The technical problems to be solved by the invention are realized using following technical scheme：
