<p><P>PROBLEM TO BE SOLVED: To provide a solid/liquid separation apparatus capable of keeping excellent separation rate for a long period while facilitating maintenance, and an organic wastewater treatment apparatus capable of increasing treatment efficiency while facilitating maintenance. <P>SOLUTION: The solid/liquid separation apparatus is used for filtering liquid containing activated sludge used for biological treatment of organic wastewater, and has a filter medium filtering the liquid. A lot of through-holes allowing passing of particles of diameters of at least 10μm are formed in the filter medium so as to be able to pass the liquid, and the filter medium is formed to collect particles of larger than 10μm and smaller than 500μm in diameters. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
