Redirection drainage type sewage treatment combined filler

Abstract

The invention discloses a redirection drainage type sewage treatment combined filler, which belongs to the field of combined fillers, and is characterized in that an air inflation and suction processis circularly carried out in a hollow soft sleeve, and a pair of arc plates is attracted by a magnetic ball to rotate clockwise and anticlockwise, so that the orientation of a water flow channel formed by the pair of arc plates is continuously changed; therefore, the flow direction of water flowing through a biofilm culturing disc is changed, water flow impact in all directions is caused to the biofilm, falling of the aged biofilm is promoted, meanwhile, the falling aged biofilm can flow out of the biofilm culturing disc rapidly, blockage is not prone to being formed in the biofilm culturing disc, and in combination with the driving effect of the arc plate on the rotating rope, a hydroformylation vinylon filament bundle is stirred by a rotating rope, an internal gap of the hydroformylationvinylon filament bundle is changed, the flow of sewage in the hydroformylation vinylon filament bundle is promoted, the aged biological membrane is further enabled to quickly flow out from the insideof the biofilm culturing disc, and a combined filler which is not easy to block and can be continuously and efficiently degraded is provided for sewage treatment.

Description

technical field [0001] The invention relates to the field of combined packing, and more specifically relates to a redirection drainage type combined packing for sewage treatment. Background technique [0002] The filler in the water treatment process usually provides a surface material (or filter material, carrier) for the growth and fixation of the biofilm. Filler is the technical core of biofilm water treatment process. It is the transfer medium of microbial biomass, microbial species, microbial activity and substances required for microbial metabolism in the biological pool. Filler is related to microbial habitat, growth and reproduction. Fillers have a significant impact on the performance characteristics and process development of biofilm processes. Therefore, the quality of the filler directly affects the efficiency of the biofilm water treatment process.

Problems solved by technology

[0005] However, when the existing sewage treatment composite filler is used, with the continuous thickening of the biofilm, the shedding rate of the formed aging biofilm is relatively slow, and generally only depends on its weak adhesion ability and the fluidity of the sewage to shed. It affects the production of new biofilm and gradually weakens the degradation ability of the filler, which affects the efficiency of sewage purification.
