Embodiment 1

[0030] See Figure 1-5 , A biofilm composite packing that slows down the aging and shedding function of biofilms, comprising an outer ring 10, the outer ring 10 is connected to the outside of the aldehyde fiber 12, the inner ring 10 is provided with an inner ring 11, an outer ring 10 and an inner ring The surface of 11 is covered with an anti-wear layer. The anti-wear layer makes the outer ring 10 and the inner ring 11 more wear-resistant in the biochemical pool, and makes the biofilm composite packing that slows down the aging and shedding of the biofilm more durable. The outer ring 10 and the inner ring 11 A plurality of connecting rods 6 are connected between the rings 11, and the plurality of connecting rods 6 are evenly arranged between the outer ring 10 and the inner ring 11, and the plurality of connecting rods 6 penetrate the inner ring 11 and are located at the inner center of the inner ring 11. Convergence, plastic branches 13 are connected between the two connecting ...

Abstract

The invention discloses a biofilm colonization composed stuffing with a function of retarding biological membrane aging and shedding. The biofilm colonization composed stuffing with the function of retarding biological membrane aging and shedding belongs to the field of biochemical pools, and comprises an outer ring, wherein hydroformylation fiber is connected to the outer side of the outer ring; an inner ring is arranged on the inner side of the outer ring; a plurality of connecting rods are connected between the outer ring and the inner ring, are uniformly distributed between the outer ring and inner ring, penetrate through the inner ring and are intersected in the central position of the inner side of the inner ring; a plastic branch is connected between each two adjacent connecting rods; a plurality of fixing pipes are inserted in the end parts, located on the inner side of the inner ring, of the connecting rods in a penetrating way; biological membrane control net mechanisms are paved on both sides of the inner ring; each biological membrane control net mechanism comprises a support net, an oxygen permeation net and a separation cavity. According to the biofilm colonization composed stuffing, a thickening process of an anaerobic membrane of a biofilm can be controlled, the aging of the biofilm is retarded, and the biofilm is not easy for shedding.

Description

Technical field [0001] The invention relates to the field of biochemical tanks, and more specifically, to a biological film-coated composite filler with the function of slowing down the aging and shedding of biological film. Background technique [0002] The biochemical tank system does not need primary sedimentation tank, secondary sedimentation tank and sludge return system, ideal static sedimentation and good separation effect. It can be used in chemical, petroleum, electric power, steel, textile, printing and dyeing, transportation, storage, food brewing, fermentation, water treatment, seawater desalination, etc. [0003] The biofilm composite packing used in the biochemical tank is a biological carrier for the treatment of wastewater by the biological contact oxidation method and anaerobic fermentation method. It is mainly used to purify the sewage through the biofilm. The biofilm is composed of highly dense aerobic bacteria and anaerobic bacteria. An ecosystem composed of ae...
