METHOD OF EXTRACTION AND TREATMENT OF MUD Russian patent published in 1995 - IPC

FIELD: extraction and processing of bottom mud. SUBSTANCE: additional reservoirs are formed in mud layer symmetrically one in the other. Water and mud layers of different viscosity are pumped out in succession into the respective reservoirs with outlet connections. The bottom of the internal reservoir is covered with a layer of ecologically pure material and filled with pure water. The cycle is repeated for subsequent reservoirs, then all internal reservoirs are extracted, and sets of additional reservoirs arranged symmetrically one in the other are installed. The process of selective extraction of mud and covering of the bottom of the additional reservoirs with a layer ecologically pure material and water is repeated. The technical facilities of mud extraction comprise a floating facility, internal reservoir of a small dimension, internal reservoir of a larger dimension, reservoir of a still larger dimension, which can be placed one in the other, facility for pumping-out of water, mud, facility for filling the worked out space, reservoir for accumulation of the first mud layer, second one, etc. EFFECT: facilitated procedure. 1 dwg
