<p>PURPOSE:To enhance treatment efficiency, by connecting reaction towers, each of which is packed with a granular high-molecular substance wherein the volume per one granule is 130mm<3> or less and matter having a volume larger than that of said substance in a mixed state, in series. CONSTITUTION:Reaction towers 1, 2, 3, each of which is packed with a packing material prepared by mixing a granular high-molecular substance having bacteria useful for the treatment of org. waste water included therein and matter having a volume larger than that of said substance, are connected in series. Branched pipes 4a, 4b, 4c of a supply pipe 4 of org. waste water are respectively connected to the bottom parts of the reaction towers 1, 2, 3 and, by adequately opening and closing the opening and closing valves 5, 6, 7 mounted to the branched pipes 4a, 4b, 4c, waste water is flowed by a pump 8.</p> |
