Embodiment Construction

[0014] Hereinafter, the structure and operation of the present invention will be described with reference to the accompanying drawings.

[0015] Figure 2A is a partial sectional view of a fluidized biofilm carrier according to the present invention, Figure 2B is its front view, Figure 2C is its top view.

[0016] The fluidized biofilm carrier according to the present invention includes a sponge-like microorganism attachment material 100 on which microorganisms attach and multiply, a specific gravity adjustment material 102 for adjusting specific gravity, and a spherical container 104 made of synthetic resin. The spherical container 104 is formed by hot-melting the two net-shaped hemispherical parts of the container, through which water flow and air bubbles can infiltrate smoothly and evenly from the outside.

[0017] The fluidized biofilm carrier of the present invention is produced by the following method.

[0018] First, the spongy microorganism attachment material 100...

Abstract

The invention relates to a fluidized biomembrane carrier and preparation method thereof, wherein the fluidized biomembrane carrier is positioned in aeration basin of waste water processing plant based on connection oxidation process. The fluidized biomembrane carrier includes: microorganism adhesive material on which microorganism attaches and reproduces, specific gravity regulation material for regulating specific gravity and spherical container prepared form synthetic resin. Water flow and gas bubble infiltrate from the outer of the spherical container formed by mesh structure. The spherical container is formed by hot melting upper and lower half-spherical cases into contact with each other.

Description

field of invention [0001] The invention relates to a fluidized biofilm carrier and a manufacturing method thereof. The fluidized biofilm carrier is installed in an aeration tank of a wastewater treatment plant based on a contact oxidation process. More specifically, the present invention relates to a fluidized biofilm carrier which is non-detachable at its coupling portion and easily assembled, and a manufacturing method thereof. The above-mentioned fluidized biofilm carrier is formed by molding a sponge-like synthetic resin, ceramic or activated carbon model in a reticulated shell, or providing a special material with microorganisms firmly attached to it, and then making the container's upper, The joint between the lower two hemispheric parts is prepared. Background technique [0002] The biofilm carrier is used in a contact oxidation process in which organic pollutants contained in wastewater are decomposed by the growth and reproduction of microorganisms attached to the ...
