<p><P>PROBLEM TO BE SOLVED: To provide an anaerobic treatment method which prevents no good contact of sludge with a substrate to effectively put the whole of a sludge bed to practical use at the time of treatment, and thus enables a stable treatment even if COD load is high, and an anaerobic treatment apparatus adapted to this treatment method. <P>SOLUTION: In a method for anaerobically treating organic wastewater or waste in an ascending flow anaerobic sludge bed treatment apparatus having gas, liquid, solid-liquid separation parts in a multistage fashion, the gas, liquid, solid-liquid separation parts which are set to an angle of 35°or less with respect to the side wall of the apparatus main body are attached within a range of 50% of the upper part of the apparatus, and raw water to be treated is supplied directly or after diluted so that the passing speed of inflow water becomes 1-5 m/h. The gas, liquid, and solid-liquid separations parts are preferably formed by baffle plates each of which has an occupying area becoming 1/2 or more the cross section of the apparatus. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
