Description

Direction-changing drainage type sewage treatment combined filler

Technical Field

The invention relates to the field of combined fillers, in particular to a direction-changing drainage type sewage treatment combined filler.

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.

However, when the existing sewage treatment combined filler is used, along with the continuous thickening of the biological membrane, the formed aged biological membrane has a slow falling rate, and generally falls off only by the weak adhesion capability and the sewage fluidity, which influences the generation of a new biological membrane, also gradually weakens the degradation capability of the filler, and influences the sewage purification efficiency.

The combined redirecting and drainage type sewage treatment filler according to claim 1, wherein: the film hanging rack comprises a lower hollow hanging rack (13) and an upper hollow hanging rack (14), the outer end of the upper hollow hanging rack (14) is fixedly connected with a plurality of inner connecting pipes (16) which are uniformly distributed, the end part of the upper hollow hanging rack (14) is fixedly connected with an air inlet hose (15), and the air inlet hose (15), the inner connecting pipes (16) and the upper hollow hanging rack (14) are communicated.

9. The combined redirecting and drainage type sewage treatment filler according to claim 8, wherein: one end of the hollow soft sleeve (1) is fixedly connected with an external connecting pipe (17) communicated with the inside of the hollow soft sleeve (1), the inner end of the external connecting pipe (17) is in threaded connection with the outer end of the internal connecting pipe (16), the other end of the hollow soft sleeve (1) is fixedly connected with a hanging rope, and the hanging rope is tied to the outer end of the lower hollow hanging rack (13).

10. The combined redirecting and draining filler for sewage treatment as claimed in any one of claims 1 to 9, wherein: the using method comprises the following steps:

s1, sequentially mounting a plurality of hollow soft sleeves (1) on a film hanging frame, and then hanging films in bacterial liquid;

s2, installing the film hanging rack and the film hanging hollow soft sleeve (1) in a sewage treatment tank, and enabling the lower hollow hanging rack (13) to be located at the bottom of the tank;

s3, introducing sewage into the treatment tank, wherein the sewage flows through the combined filler and is subjected to oxidative degradation by the combined filler, and the thickness of the biofilm on the film hanging disc (2) is continuously increased;

s4, the air inlet hose (15) is circularly inflated and aspirated, the arc board (3) is urged to rotate back and forth outside the membrane hanging disc (2), the flow direction of sewage on the membrane hanging disc (2) is continuously changed, and meanwhile, the hydroformylation vinylon tows (22) are driven by the rotating rope (11), so that the falling of the aged biomembrane is promoted together.
