METHOD OF SEWAGE WATER PURIFICATION FROM OIL PRODUCTS AND DEVICE FOR ITS IMPLEMENTATION

FIELD: chemistry. ^ SUBSTANCE: sewage water to be purified is supplied to cathode electric floatator chamber and is processed with hydrogen bubbles, float sludge is removed and gaseous hydrogen is extracted from it, purified from dispersed contaminations water is supplied to anode electric floatator chamber by recycling and saturated with oxygen bubbles. Then both flows are mixed, purified by filtering water in granular catalytic material, from additionally purified water gaseous oxygen is extracted, extracted gaseous hydrogen and oxygen are supplied separately to hydrogen and oxygen chambers of fuel electrochemical current source, whose electric energy is used for carrying our electric floatation. Device contains electric floatator with electric power source and system of float sludge collection. Electric floatator contains cathode and anode chambers, separated with permeable for current membrane, two systems of electrodes, consisting of anode and cathode, first system of electrodes being connected to constant current power source, second - to fuel electrochemical current source, cathode chamber is separated into sections with vertical partitions, adjoining with its upper part to foam-collecting device, outlet of anode and cathode chambers is joined with one cavity. ^ EFFECT: increase of degree of water purification from dissolved organic substances. ^ 9 cl, 1 dwg, 1 tbl
