<p>PURPOSE:To form a binder for biological membranes having an extremely high effect of holding microorganisms by constituting the surface of a sheet, film or molding of a synthetic resin having tackiness. CONSTITUTION:The surface of the sheet, film or molding is constituted of the synthetic resin having the tackiness (e.g., ethylene/vinyl acetate copolymer, polyisobutyrene, polyurethane resin). The binder for the biological membranes constituted of such synthetic resin adheres to the microorganisms with strong power when the microorganisms stick to the surface thereof. Said binder sticks the biological membranes extremely securely without stripping the same with such physical power as water flow or foam. The effect of a sewage treatment is thus improved.</p> |
