DEVICE FOR PURIFICATION OF DRAINAGE WATERS FROM SOLID HOUSEHOLD WASTES GROUND Russian patent published in 2011 - IPC C02F9/00 

FIELD: technological processes.

SUBSTANCE: invention is intended for utilisation of organic wastes on places of their immediate formation or collection. Device for purification of drainage waters from solid household wastes ground contains separating tank and system of reservoirs and filters. Separating tank is made in form of elongated hollow of trapezoidal form, adjacent to one of dump pile slopes, with installation in it of pump which supplies drainage waters into electrolyser-activator, whose output is connected with reservoir, in which installed is pump, pumping polluted sediment into filter-press, where separation of liquid and solid phases of sewage takes place. Liquid is directed into sand filter, sediment is removed into ground pile. Sand filter is connected with cartridge filter, connected with reservoir, whose output is connected with installation of membrane purification of drainage waters, which in its turn is connected with adsorber, from which discharge of purified waters on ground soil is performed. Washing waters from sand filter are supplied into ground pile, concentrate from installation of membrane purification of drainage waters is also supplied onto ground.

EFFECT: increased productivity of neotralisation and utilisation of organic wastes.
