Abstract
A vacuum-flocculation-solidification integrated apparatus for waste mud and a using method thereof are provided, and the apparatus includes an outer support truss, a vacuum barrel wall, a flocculation stirring device, and a rotary spraying solidification device. The using method of the apparatus includes: flattening a site and installing a support truss and a vacuum barrel wall; assembling a flocculation stirring device and then hoisting and installing to a top of the vacuum barrel wall; checking an air tightness; adding an APAM flocculant, starting the flocculation stirring device and a vacuum pump; starting an air compressor; and squeezing solidified soil from soil outlets. Beneficial effects of apparatus are that: multiple procedures of flocculation, vacuum drainage, solidification and discharging soil for the waste mud are continuously performed; a solidification agent is fully mixed with solidified soil through rotary spraying; and the apparatus is convenient to be disassembled, reassembled, and reused.
