A bio-film composite filler with the function of slowing down the aging and shedding of biofilm

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 pools, and more specifically relates to a biofilm-hanging composite filler with the function of slowing down the aging and shedding of biofilms. Background technique [0002] The biochemical tank system does not need primary settling tank, secondary settling tank and sludge return system, ideal static settling and good separation effect. It can be used in chemical industry, petroleum, electric power, steel, textile, printing and dyeing, transportation, storage, food brewing, fermentation, water treatment, seawater desalination, etc. [0003] The biofilm composite filler used in the biochemical pool is a biological carrier for the treatment of wastewater by biological contact oxidation and anaerobic fermentation. It mainly realizes the purification of sewage through biofilm. Biofilm is composed of highly dense aerobic bacteria, anaerobic bacteria The ecosystem composed of aerobic bacteria, facultative b...

AI Technical Summary

Problems solved by technology

[0004] In the process of thickening the anaerobic film of the biofilm: the increase of anaerobic metabolites leads to the destruction of the balance between the anaerobic film and the aerobic film; the continuous escape of gaseous products weakens the adhesion of the biofilm to the filler Ability; become an aging biofilm, its purification function is poor, and it is easy to fall off
