<p><P>PROBLEM TO BE SOLVED: To provide an apparatus for treating garbage water capable of reducing the propagation of a noise and a vibration to the ground floor layer part of a building by reducing the noise and the vibration accompanying aeration made inside a treatment tank installed on the underground floor layer part of the building such as collective housing. <P>SOLUTION: A diffuser pipe 4 radiates air supplied from a blower 6 through an air supply pipe 5 from the inner peripheral part of the diffuser pipe 4 to the inside of the treatment tank 2. This diffuser pipe 4 is a soft tubular body arranged on the bottom part in the treatment tank 2 and formed so as to flex freely, and includes a number of micropores communicating with the inner peripheral part over the whole outer peripheral face. Further, the diffuser pipe 4 is extended from one end side to the other end side of the bottom face 2a of the treatment tank 2 and a plurality of diffuser pipes are provided side by side in a direction orthogonal to the extending direction (depth direction in figure) roughly at an even interval. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
