Problems solved by technology

[0007] Aiming at the problems existing in the prior art, the object of the present invention is to provide a three-state driven off-mode suspended filler for sewage treatment, which is dispersed and distributed in the sewage through the three-state mixing ball group, and driven by the water flow to the inner wall of the inner reticulated shell. Realize multi-directional collision, so that the double-capsule breaking hammer expands outward and rotates and tilts inside the membrane-attached silk layer, penetrates into the inside of the membrane-attached silk layer, destroys the integrity of the biofilm inside the membrane-attached silk layer, and ruptures the biofilm , through the destruction of the biofilm, on the one hand, the sewage can enter the interior of the film-attached silk layer more quickly, improve the fluidity of the sewage in the biofilm, make the sewage fully contact with the biofilm, and improve the degradation efficiency; on the other hand, It can effectively destroy the adhesion strength of the biofilm on the membrane-attached silk layer, so that the broken aged biofilm can fall off the membrane-attached silk layer more quickly and smoothly, thereby greatly reducing the plugging of the filler and further improving the filler's performance. Degradation efficiency

Embodiment

[0040] see figure 1 and figure 2 , a kind of three-state induced off-mode suspension filler for sewage treatment, comprising an outer reticulated shell 1, an inner reticulated shell 2 is arranged on the inner side of the outer reticulated shell 1, and a pair of mutually parallel reticulated shells are fixedly connected between the outer reticulated shell 1 and the inner reticulated shell 2 And with respect to the chain piece 3 symmetrical to the center of the outer reticulated shell 1, an annular water channel is opened on the outer reticulated shell 1, and the annular water channel is located between a pair of connected plates 3, and a three-state mixing ball group 4 is placed on the inner side of the inner reticulated shell 2, The three-state mixing ball group 4 is formed by mixing floating balls, suspension balls and sinking balls at a ratio of 1:1:1. The outer reticulated shell 1 and the inner reticulated shell 2 are filled with a film-attached silk layer 5, and the inner...

Abstract

The invention discloses a three-state actuated demoulding type suspended filler for sewage treatment, and belongs to the field of fillers for sewage treatment. Three-state mixed ball groups are dispersedly distributed in sewage and are driven by water flow to realize multi-directional collision with the inner wall of an inner reticulated shell, so that a double-bag membrane breaking hammer is outwards expanded and rotationally inclined in a membrane attaching wire layer, and penetrates into membrane-attached filament layer to destroy integrity of biological membrane in membrane-attached filament layer, the biological membrane is broken; by destroying the biological membrane, on one hand, the sewage can enter the membrane-attached filament layer more quickly, the flowability of the sewage in the membrane-attached filament layer is improved, the sewage is in full contact with the biological membrane, and the degradation efficiency is improved by destroying the biological membrane, and onthe other hand, the adhesion strength of the biological membrane on the membrane-attached filament layer can be effectively destroyed, so that the crushed aged biological membrane can fall off from the membrane-attached filament layer more quickly and smoothly, thereby greatly reducing the blockage of the filler and further improving the degradation efficiency of the filler.

Description

technical field [0001] The invention relates to the field of fillers for sewage treatment, and more specifically relates to a three-state driven off-mode suspension filler for sewage treatment. Background technique [0002] The biofilm method is a sewage treatment method that uses biofilm to stabilize and clarify wastewater under sufficient oxygen supply conditions. The filler in the water treatment process usually provides the surface material (or filter material, carrier) for the growth and fixation of the biofilm. The biofilm can be divided into anaerobic layer, aerobic layer, attached water layer, mobile water layer. 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. [0003] Renewal and shedding process of biofilm: With the decomposit...
