METHOD TO STORE RUN-OFF OF INDUSTRIAL PLANTS WITH VARIOUS FILTRATION PROPERTIES Russian patent published in 2009 - IPC B09B1/00 E02B7/06 

FIELD: environment protection.

SUBSTANCE: invention relates to environment protection, in particular to the method to store run-off of industrial plants with various filtration properties. The method involves stratified aggradation, periodical construction of dikes from run-off with high filtration coefficient all around newly aggrading run-off. Slurry of hydraulic fill is prepared directly on a dump, the dump is sluiced by section with dividing embankment, flood dikes are constructed from run-off with high filtration coefficient by aggrading on one lot, additionally the size of constructed dikes is bigger that is necessary for construction of flood dikes, the dump is sluiced by mixture of run-off with high and low coefficient of filtration on the other lot and dividing embankments are raised. The dump is sluiced and flood dikes are constructed by turn as the lots are filled with mixture, till the dump is raised to required altitude.

EFFECT: method allows decreasing square of sludge depository, as well as storing tails having various filtration properties and appearing during enrichment.
