Abstract
PURPOSE: To economically and simply treat sludge by a method in which a framework is installed on the bottom under water, where sludge deposits, while a flocculant is added to the sludge inside the framework to flocculate the sludge, and then the sludge so treated is compacted and covered with soil.
CONSTITUTION: A framework 1 is installed on the bottom 2 under water, where sludge 3 deposits, and then an anionic high molecular flocculant is added to the sludge 3A inside the framework 1 with stirring to flocculate the sludge 3A. After the flocs are settled, water inside the framework 1 is drawn out by a pump, the sludge solids are compacted by weights or air pressure to reduce their volume greatly, and then soil and sand are covered on the sludge so compacted on the bottom to confine it.
