Porous honeycomb spongy biological bed and installation method thereof

Abstract

The invention discloses a porous honeycomb spongy biological bed and an installation method thereof. A spongy material for the biological bed is made into a cuboid or cube block; a horizontal plane is provided with a plurality of vertical sewage holes; a large quantity of small holes are formed in a space where the sewage holes are not formed in the spongy block; sludge for growing bacteria and accommodating bacterial communities is filled into the small holes; the biological bed can be used for making polyurethane sponge, cement, pottery clay or fire rock; strengthened aggregate can be added into the polyurethane sponge; a plurality of cube blocks are piled into a large cube; the sewage holes on upper and lower cuboid or cubes are communicated over against each other; and a steel rib, a rope or a pipe is used for connecting a plurality of cuboids or cubes into a biological bed string which can be tightly fixed in a sewage pool in a multipoint suspension way. The spongy material and a porous honeycomb structure are most suitable for the adhesion and growth of sludge containing bacteria; after sewage treatment is performed, a specific surface is not decreased greatly; and a regularly hexagonal porous honeycomb structure is adopted, so that a specific surface area between bacteria and sewage is largest, a utilization ratio is highest, and sewage flow property is high. The porous honeycomb spongy biological bed is applied to a sewage treatment system.

Description

[0001] (1) Technical field: the present invention is a kind of biological filler for sewage treatment system. It belongs to the category of sewage treatment (C02F). (two) background technology: [0002] The principle of sewage biological purification in the sewage treatment system is to put bacteria and biological flora in the sewage to swallow the organic matter and pollutants in the sewage, so as to purify the sewage. At present, the sewage biological purification treatment methods include activated sludge method and biological packing method. The activated sludge method is in a circulating sewage system, using the bacteria growing in its own sludge to swallow the organic matter in the sewage, and the circulating water provides oxygen. The bacteria are aerobic bacteria, and this method must provide circulating water. The biological filler method is to put a special biological filler in the sewage as a carrier to provide a growth place for the bacteria flowing through the se...

AI Technical Summary

Problems solved by technology

[0004] The porous honeycomb sponge-like biological bed provided by the present invention is to solve the problem that the existing biological fillers used in the sewage treatment system have small specific surface, less bacteria load or greatly reduced specific surface after operation, and it is difficult to meet the needs of sewage treatment.
