<p><P>PROBLEM TO BE SOLVED: To prevent a decrease in decomposition efficiency of sludge accompanying operation continuance in an ultrasonic wave type sludge solubilization processor. <P>SOLUTION: The sludge solubilization processor 11 includes a solubilization tank 25 which sewage containing sludge flows in from an inflow port 26 and also flows out from an outflow port 27. In the solubilization tank 25, a transducer 39 generating an ultrasonic wave is arranged. A washing nozzle 42 is arranged so as to turn a discharge port 39a towards the transducer 39. After a water discharge valve 29 is opened to discharge sewage in the solubilization tank 25, washing water is supplied to a washing nozzle 31 to be ejected to the transducer 39. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
