<p>PURPOSE:To treat waste water rapidly by forming the main body of an immobilizing carrier with a porous body having two-dimensional or three-dimensional through-pores and reducing the diameter of the through-pores successively from the upper layer to the lower layer. CONSTITUTION:Filaments 3 having from 0.1 to several mm diameter is formed into a porous body 1 having two-dimensional or three-dimensional through-pores 2 and an immobilizing carrier main body A of specified size is formed with the porous body 1. The diameter of the through-pores are successively reduced from the upper layer to the lower layer. By using this microbe-immobilizing carrier for a waste water treating apparatus, the clogging of a filter bed by hardly decomposable suspended matter contained in waste water is prevented, opportunities of the contact with microbes are increased, fermentation is efficiently carried out and waste water is rapidly treated.</p> |
