<p>PROBLEM TO BE SOLVED: To efficiently, continuously and rapidly treat sludge by a method wherein fermentation treatment is advanced by mixing the sludge and bacteria in a sludge treating apparatus, and vapor with deodorizing effect is taken out by the fermentation heat and while deodorization of the sludge with the vapor is performed, the sludge is sucked into a plurality of sludge-treating apparatuses where treatment is not advanced yet. SOLUTION: When material to be treated reaches a sludge suction site, at first, an open/close control cock 22 fitted on a sludge suction pipe 20 is opened, and then, an open/close control cock 42 for controlling inflow of a deodorizing vapor is opened. Then, the vapor with deodorizing effect generated from a urine-treating apparatus where fermentation treatment has been advanced is taken out and the sludge is sucked by means of a suction hose 4 using a suction pump and is sent into an advanced treating apparatus. In this instance, a deodorizing vapor is ejected from a deodorizing vapor ejecting hole fitted in the neighborhood of a suction hole of the sludge to suppress heavy odor of the sludge. On the other hand, the odor evacuated from a vent hole 48 can also be suppressed with the deodorizing vapor.</p> |
