An organic wastewater treatment apparatus includes (a) a treatment tank, (b) a plurality of membrane separation devices immersed in the treatment tank, where each membrane separation device is provided with a diffuser device and a permeated liquid extracting device, (c) a plurality of sludge characteristics measuring devices dispersedly disposed in the treatment tank, and (d) a controller. An operating method divides the treatment tank into a plurality of regions, and sets at least one of an amount of air diffusion and a flow rate of permeated liquid for each membrane separation device based on a measured value of the sludge characteristics measuring device disposed in the corresponding region. The controller sets at least one of the amount of air diffusion and the flow rate of permeated liquid based on the measured value of the sludge characteristics measuring device in a vicinity of which the membrane separation device is disposed.
