<p><P>PROBLEM TO BE SOLVED: To provide an organic wastewater treatment method capable of reducing an installation space, or the like, in multistage biological treatment and capable of obtaining treated water of high quality. <P>SOLUTION: This organic wastewater treatment method is constituted so as to treat organic wastewater by microorganisms under an aerobic condition and includes a first biological treatment process for subjecting organic wastewater to aerobic biological treatment under a high load condition of 1 kgBOD (biological oxygen demand)/m<SP>3</SP>/day or above, a process for flocculating and separating treated water obtained by treating the organic wastewater in the first biological treatment process by flocculation treatment using a flocculant and a second biological treatment process for subjecting the treated water obtained in the flocculation and separation process to aerobic biological treatment under a load condition lower than the high load condition in the first biological treatment process. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
