| titleOfInvention | Hollow fiber membrane, hollow fiber membrane module, waste water treatment device and waste water treatment method |
| abstract | An object of the present invention is to provide a hollow fiber membrane, a hollow fiber membrane module, a waste water treatment apparatus, and a waste water treatment method in which a microbial layer is easily formed. SOLUTION: A hollow fiber membrane 1 for waste water treatment in which a microbial layer 6 derived from microorganisms or fungi in waste water is formed on the outer surface during waste water treatment, and is measured under the following measurement conditions. A hollow fiber membrane 1, wherein the surface zeta potential of the hollow fiber membrane 1 is -8 mV or higher. (Measurement condition) Using a particle dispersion (pH=6 at 25° C.) obtained by diluting polystyrene latex with a solid content concentration of 0.25% by mass and an average particle size of 500 nm by 150 times with a 10 mM sodium chloride aqueous solution, a plurality of the hollow fiber membranes were plated. The surface zeta potential of the hollow fiber membrane is calculated from the zeta potential measurement results of the polystyrene latex by electrophoresis while the samples are laid side by side on the sample mounting surface of the measurement cell without any gaps, and are in close contact. .
