Abstract

PURPOSE:To enable an efficient bulk treatment of an original waste water by attaching an air waste-water supply pipe, an air/treated-water discharge pipe and an air charge/ discharge pipe to a closed vessel inside which packed beds consisting of packing particles and a space including a collecting part for wash-concentrated waste water. CONSTITUTION:Packed beds 21 and 22 consisting of packing particles and a space A including a collecting part for wash-concentrated waste water is arranged inside a closed vessel 11. An air/waste-water supply pipe 1 which is led to the bottom part of the packed bed, an air/treated-water discharge pipe 2 which is led to the surface of the packed bed and an air charge/discharge pipe which is led to the space A are also attached to the vessel 11. That is to say, the packed beds are used efficiently in an ideal condition as a whole, because the original waste water can be allowed to flow first through a coarse particle bed and then through a fine particle bed. And a treatment duration becomes longer, because the captured amount of microbes and SS become larger. Further, a stable operation is possible, because the packing particles do not move in case that bubbles due to the original waste water or microbe treatments stick to the packing particles.
