<p>PURPOSE:To make it possible to deodorize an odorous gas generated in anaerobic treatment stably and with high efficiency by providing a simple device and operating it. CONSTITUTION:Untreated water, water in the process of anaerobic treatment or anaerobic treated water 11 is conducted to a deodorizing tank 5, so that the water is mixed with microbes in the tank, then an odorous gas 14 generated in the anaerobic treatment is bleeded into the deodorizing tank 5 with air for aerobic treatment, in a method for anaerobic treatment of organic drained water. The water conducted into the deodorizing tank 5 is allowed to run in a single pass so that its held time in the deodorizing tank 5 lasts for more than one day.</p> |
