Abstract

[Object] Provided is a method for performing efficient biological treatment in two-stage biological treatment of organic wastewater after reducing tank volume and reducing the capacity and size of an overall wastewater treatment facility. [Solution] A biological treatment apparatus provided with: a feed water adjustment and first biological treatment tank (11) to which organic wastewater is supplied as feed water and which adjusts a water amount and performs aerobic biological treatment in a one-pass mode; and a second biological treatment tank (3, 12) that performs aerobic biological treatment of the first biological treated water. The biological treatment apparatus is operated such that an instantaneous hydraulic retention time (HRT) of the feed water adjustment and first biological treatment tank (11) at the time of feed water inflow is from 2 to 8 hours and a water level is equal to or higher than 40% of a water level at the time of full water. A function of a first biological treatment tank (2) is provided to the feed water adjustment tank (1), whereby the first biological treatment tank (2) is omitted and the volume of the overall wastewater treatment facility is reduced.
