<P>PROBLEM TO BE SOLVED: To provide a membrane separation activated sludge processing apparatus and a membrane surface washing method of the membrane separation activated sludge processing apparatus which does not require complicated operation management, makes such highly efficient membrane surface washing as to hardly cause membrane surface blocking possible and does not accompany air diffusion of excessive air amount. <P>SOLUTION: The membrane separation activated sludge processing apparatus is characterized in that an immersion type membrane separation device is arranged in a reaction tank, an air diffuser is arranged on the lower side of the immersion type membrane separation device and a water jet device having a submerged pump disposed outside the range on the vertically lower side of the immersion type membrane separation device and on the lower part of the reactor tank as a power source, is disposed on the upper side or the lower side of the diffuser. <P>COPYRIGHT: (C)2012,JPO&INPIT |
