Description

Wire drawing is gathered formula combined packing for sewage treatment

Technical Field

The invention relates to the field of combined fillers, in particular to a combined filler for wiredrawing and gathering sewage treatment.

Background

The filler for water treatment process is usually the surface material (or filter material, carrier) for providing attachment growth and fixation for the biological membrane. The filler is the technical core of the water treatment process by the biomembrane method, is a transfer medium for the microbial biomass, the microbial species, the microbial activity and substances required in the microbial metabolism process in the biological pond, and is related to the inhabitation, growth and reproduction of the microbes. Fillers have a significant impact on the performance characteristics of the biofilm process and process development. Therefore, the quality of the filler directly influences the efficiency of the water treatment process by the biofilm method.

The process of updating and falling off the biological membrane comprises the following steps: along with the decomposition of organic matters, the thickness of the biological membrane is continuously increased, the inner deep part which can not be penetrated by oxygen-containing gas is converted into an anaerobic state, anaerobic metabolites are increased, the balance between the anaerobic membrane and the aerobic membrane is damaged, gaseous products are continuously escaped, the adhesion capacity of the biological membrane on the filler is weakened, the biological membrane becomes an aged biological membrane, the purification function of the aged biological membrane is poor, the biological membrane is easy to fall off, and after the biological membrane falls off, a new biological membrane can grow again to continuously purify sewage.

The sewage treatment filler has various types: the composite filler comprises soft fiber fillers (PE center rope + hydroformylation vinylon filament bouquet), semi-soft fillers (PE center rope + PE ring sheet), composite fiber fillers (PE center rope + PE ring sheet + hydroformylation vinylon filament bouquet), elastic three-dimensional fillers (PE center rope + PP elastic filament), suspension fillers (PE spherical shell + hydroformylation vinylon filament bouquet or PP wide flat filament band), obliquely-suspended porous suspension fillers (PP), plum blossom rings (PP), fiber ball fillers (polyester fiber), honeycomb oblique/straight tube fillers (PP or PVC) and the like.

In current sewage treatment packs, some are big because of the clearance that the filler set up, are difficult for carrying on the biofilm formation when using, and the biological adhesion volume is low, and some packs are for improving biological adhesion volume, and it is intensive to distribute between the filler, and the clearance is little, but the flow resistance that produces when using is great, and the rate of droing of the ageing biomembrane that the degradation formed is slower, forms the jam in the biomembrane is inside, has influenced the contact of sewage with the biomembrane, causes the degradation performance decline of filler.
