<P>PROBLEM TO BE SOLVED: To provide a method and apparatus for treatment of biological wastewater, capable of stable filtration for a long period of time, by reducing clogging of membranes in a membrane separation sludge method. <P>SOLUTION: The biological wastewater treatment method includes a step of introducing the wastewater into a sludge, a step of obtaining a treated water by biologically treating the wastewater introduced into the sludge, and a step of performing solid-liquid separation using the membrane with respect to the sludge and the treated water, wherein the method further includes a step of adding a protein adsorbent to the wastewater or the sludge. The biological wastewater treatment apparatus includes a biological reactor for obtaining the treated water by retaining the sludge and biologically treating the wastewater introduced into the sludge, and the membrane for performing the solid-liquid separation with respect to the sludge and the treated water, wherein the biological reactor contains the protein adsorbent. <P>COPYRIGHT: (C)2013,JPO&INPIT |
