摘要: A system for treating waste water using a particulate body formed by covering and fixing nitrifying bacteria. In the system, the particulate body is inserted in a nitrifying vessel which including therein an air diffusion device for supplying oxygen to the nitrifying bacteria and a particulate body separation device for preventing the outflow of the particulate body. The nitrifying vessel and the particulate body contained therein are used as a nitrifying vessel unit and one or more such nitrifying vessel units are arranged within a treating tank. Waste water is circulated between the nitrifying vessel and the other portions of the treating tank than the nitrifying vessel by means of the air lift effect of the air diffused from the air diffusion device.
