PROBLEM TO BE SOLVED: To provide a treatment method for organic polluted water and an apparatus therefor capable of cleaning treatment for the high-concentration organic polluted water, as it is, containing a solid organic matter such as sewage water without producing sludge. SOLUTION: The decomposition treatment method in a cleaning area for the organic matter in the sewage water or waste water from a food factory comprises a decomposition process for a dissolved organic matter in the water to be treated chiefly by aerobic bacteria in an aerobic treatment area of the cleaning area, a decomposition process for a solid organic matter in the water to be treated chiefly by anaerobic bacteria in an anaerobic treatment area of the cleaning area, and a decomposition process for the organic matter chiefly by Tsukisei (gas-permeable) bacteria in a transition area which the water to be treated passes through and is formed at the border between the aerobic treatment area and the anaerobic treatment area. A plurality of the treatment units each of which comprises the three types of the decomposition processes mentioned above are carried out repeatedly, and, moreover, the first treatment and the last treatment in the cleaning area are both the aerobic treatment processes.
