Layered sedimentation-type artificial zoogloea and preparation method thereof

Abstract

The invention discloses a layered sedimentation-type artificial zoogloea and a preparation method thereof, and belongs to the technical field of wastewater treatment. The layered sedimentation-type artificial zoogloea comprises a first zoogloea attachment frame and a second zoogloea attachment frame; a vertical-shaft upright rod is arranged in the first zoogloea attachment frame; and the second zoogloea attachment frame sleeves the lower end of the vertical-shaft upright rod. The first zoogloea attachment frame and the second zoogloea attachment frame are both rotationally connected with the vertical-shaft upright rod, so that the zoogloea can be distributed in different sewage layers, the zoogloea can conveniently exert a treatment effect on impurities in the different sewage layers, andthe oxygen generation rate is increased. Meanwhile, influence of fine foam generated by filamentous bacteria is reduced by the self structure, so that a large amount of bubbles can be condensed and converged to form larger foam, then the foam can be easily broken, accumulation of the foam in the zoogloea can be reduced, oxygen obtained after the reaction of the zoogloea is promoted to diffuse outwards, and thus treatment efficiency of the zoogloea on the sewage is improved.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, and more specifically relates to a layered sedimentation type artificial bacteria micelle and a preparation method thereof. Background technique [0002] Bacterial micelles are fine particles composed of bacteria and colloidal substances secreted by them. They are the main body of activated sludge. The properties of sludge adsorption, oxidation and decomposition, and coagulation and sedimentation are all related to bacterial micelles. Bacteria, because they are embedded in colloid, are not easy to be swallowed by protozoa, which is conducive to sedimentation. The shapes of the bacteria micelles are spherical, mushroom-shaped, oval, branched, pendant and irregular. All bacteria micelles are found in the activated sludge. The typical one is the genus Kinetoglia, which has two Species: Dendritic Kinetoglia and pendulous (hanging) filamentous Kinetoglia. [0003] Bacterial micelles ar...

Problems solved by technology

[0006] Although the above-mentioned technical solution proposes microbial micelles suitable for the treatment of high-concentration organic wastewater that meet the discharge requirements, when the microbial micelles are used in the sewage treatment process, after the staff put the microbial micelles into the sewage, Due to the complexity of the internal components of the sewage, after a period of standing, the sewage is prone to stratification with the composition of the components, and the microbial micelles with the same content are easy to float in the same concentration layer in the stratification of the sewage. In the sewage, the sewage treatment effect is reduced, and the original sewage treatment effect cannot be exerted. At the same time, the bacterial micelles partially grow to produce filamentous bacteria during the growth process, and the slight shaking of the filamentous bacteria in the sewage will produce fine foam. A large amount of foam accumulates near the bacteria micelles, blocking the diffusion of oxygen after the bacteria micelles react to the outside, reducing the efficiency of bacteria micelles for sewage treatment
