| 摘要 |
<p>The present invention relates to a drum concentrator and, more specifically, a drum sludge concentrator which enables a raw sludge solution stored in a sludge storing container to flow in a drum and the drum to be rotated, thereby concentrating the sludge and collecting residual solution after dehydration wherein the drum sludge concentrator comprises a drum which is made by folding a flat plate whose thickness is 0.5-1.5 t in a round shape and has a plurality of permeable holes whose diameter is 0.5-1.5Ø, thereby dehydrating concentrated sludge while rotating; a washing device which sprays a washing solution to the permeable hole on the drum from the outside; and a discharging screw which is installed in the drum to discharge the concentrated sludge.</p> |
