<p><P>PROBLEM TO BE SOLVED: To provide a device for concentrating sludge that can eliminate the settling property of sludge by water spraying, etc., to separate and remove anaerobic bubbles entangled with the sludge, and prevents a decrease in the concentration and separation performance in a sludge concentrating tank and an associated increase in an amount of concentrated sludge. <P>SOLUTION: The device for concentrating sludge includes: a sludge concentrating tank 1 for separating sludge into a concentrated sludge and a concentrated and separated liquid; a sludge delivery pipe 2 for delivering sludge to the sludge concentrating tank 1; an water injector 3 provided inside the sludge delivery pipe 2, and for jetting water to the sludge delivered through the delivery pipe; a sprinkler 4 provided outside the sludge delivery pipe 2, and for spraying water to the sludge delivered through the delivery pipe; and a water feeder 5 provided inside the sludge concentrating tank 1, and for feeding water to a water surface of the tank. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
