Fill it as a material. Then, 100 ml of culture solution for methane bacteria was added to each glass column, and the gas phase was replaced with Nt-C.
Oo (80:20)? % synthetic gas and methane fermentation was carried out at a temperature of 25° C. 7. Culture was continued for about 20 days to form a biofilm of methane on the P material. After that, the culture solution was extracted from the cock at the bottom of the column to remove microorganisms not attached to the ν material, and the ν material in the column was further washed with a methane bacteria medium. was added, and the gas phase was replaced with No, -CO, and mixed gas until the medium turned from red to yellow, and methane fermentation was performed at a temperature of 25°C. Continue methane fermentation for 30 days,
The amount of gas generated in each column was measured.

適なものである。The measurement results are shown in Figure 1, where a is a porous polymer material made by adding hydroxyl abatite to polyethylene, h is a ceramic bead, C is a surf shell, and d is a porous polymer material made of only polyethylene as the furnace material. This is the amount of gas generated by the column used. As you can see from this graph! I! The amount of gas generated when using the furnace material according to the example is considerably higher than when using other furnace materials, so the porous body made by adding a calcium phosphate-based substance to polyethylene is suitable for ceramic beads. The surface adhesion of methane bacteria is better than that of surf clams or surf shells, and that of porous bodies made only of polyethylene, which means that it is easier to form a biological pancreas on the surface, and the amount of gas generated during the initial stages rises quickly, thus making it easier to adhere to the surface. It is suitable as a furnace material.

いった効果がある。Effects of the F8 invention As described above, with the immobilized furnace material using a polyethylene porous body to which a calcium phosphate-based substance is added, the adhesion of microorganisms on one surface is absorbed, and the outflow of living organisms is reduced. Therefore, for example, the ability to purify organic wastewater is stabilized. Furthermore, since microorganisms adhere to the furnace material quickly, the period from startup to steady operation can be shortened. Since a polymer material is used, it is lightweight, easy to mold to obtain a desired shape, and low cost.
