FIELD: water treatment. SUBSTANCE: simultaneously are carried out: bringing water containing dissolved organics into contact with semiconductor photocatalyst, ultraviolet irradiation, and separation of cleaned water from photocatalyst by filtering liquid through porous membrane. The latter is of dynamic or ceramic type of semiconductor material. Process is intensified by active oxidants: oxygen, hydrogen peroxide, or ozone. Gas oxidants can be supplied through gas-permeable waterproof membrane. EFFECT: enabled rapid and complete removal of dissolved organics, including toxic and hard-degradable chlorinated substances. 9 cl, 1 tbl |
