Method.
Background technology
In biomembrance process, the filler place inhabited of being rely as microorganism is one of key technology of wastewater treatment, its
Performance directly affects treatment effect and investment cost.Since the 1970s, researcher just using improve filler as
Breach, constantly promote the development of biomembrance process.At present, domestic conventional filler is honeycomb filler, soft-filler, semi-soft filled out
Material and the fixed filler such as floating stuffing, but often to run into blocking, conglomeration, gas distribution water distribution in use uneven etc. for these fillers
Problem, it have impact on biological treatment effect.And above-mentioned filler is both needed to be arranged on auxiliary stand, cause filler installation, replacing etc. all
It is more inconvenient, make construction investment and the relative raising of operational and administrative expenses.The exploitation of floating stuffing is current both at home and abroad for filling out above
The deficiency of material, the new research trends triggered by organism fluidization bed process.This filler proportion close to water, without
Fixed support, Quan can be suspended in water in pond with aeration agitation, simultaneously pond is even fluidizing, and energy consumption is relatively low, is before one kind has development very much
The filler on way.Filler product in the market has a lot, but in actual applications there is it is certain the problem of, such as specific surface area
Small, hydrophilicity is poor, and biofilm and startup cycle are long, biomembrane is easy to fall off etc..Many companies try hard to from the improvement in structure and answered
Hydridization improves the specific surface area of filler, improves treatment effect, subject matter is that filling-material structure is more complicated, and cost is higher, and raw
