Air from the source of atmospheric air is passed by the source of ultraviolet light while simultaneously being exposed to magnetic flux from the magnet, thereby creating a plurality of multivalent oxygen ion allotropes. The apparatus delivers the atmospheric air containing multivalent oxygen ion allotropes to the livestock waste, thereby reducing odor. A method for deodorizing livestock waste, has the steps of: pumping waste from a holding tank; exposing atmospheric air to ultraviolet light and magnetic flux, thereby creating a plurality of multivalent oxygen ion allotropes; exposing the waste to the air containing the plurality of multivalent oxygen ion allotropes; and returning the waste to the holding tank. ## Claims ### Claim 1 Apparatus for deodorization of livestock waste, comprising: (a) a tank containing livestock waste to be deodorized; (b) a source of atmospheric air; (c) a source of ultraviolet light; and (d) a magnet; (e) wherein air from the source of atmospheric air is passed by the source of ultraviolet light while simultaneously being exposed to magnetic flux from the magnet, thereby creating a plurality of multivalent oxygen ion aflotropes; and (f) apparatus for delivering the atmospheric air containing multivalent oxygen ion allotropes to the livestock waste, thereby reducing odor, wherein the apparatus for delivering the atmospheric air to the livestock waste in the tank further comprises a venturi; (g) further comprising a pump removing waste from the tank, passing the waste through the venturi, and piping to return the waste to the tank. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the waste flowing though the venturi creates a vacuum, pulling atmospheric air past the source of ultraviolet light and the magnet. ### Claim 3 (depends on 1) The apparatus of claim 1, further comprising a control system. ### Claim 4 (depends on 3) The apparatus of claim 3, further comprising a float valve in the tank sensing the level of waste in the tank and signaling the waste level to the control system. ### Claim 5 (depends on 4) The apparatus of claim 4, wherein the control system controls the source of ultraviolet light, based on the signal from the float valve. ### Claim 6 (depends on 4) The apparatus of claim 4, wherein the source of ultraviolet light is an ultraviolet lamp, and wherein the control system makes and breaks connections between a ballast box and the ultraviolet lamp. ### Claim 7 (depends on 4) The apparatus of claim 4, further comprising a pump removing waste from the tank, passing the waste through the venturi, and piping to return the waste to the tank, wherein the control system controls the pump. ### Claim 8 (depends on 1) The apparatus of claim 1, further comprising an air filter between the source of atmospheric air and the source of ultraviolet light. ### Claim 9 (depends on 1) The apparatus of claim 1, further comprising a check valve between the source of atmospheric air and the tank. ### Claim 10 (depends on 4) The apparatus of claim 4, further comprising at least two electrodes acting upon the waste to remove dissolved impurities. ### Claim 11 (depends on 10) The apparatus of claim 10, wherein the electrodes pass direct current through the waste and wherein the polarity of the electrodes is periodically reversed. ### Claim 12 (depends on 10) The apparatus of claim 10, wherein the dissolved impurities consist essentially of metal ions and carbamates. ### Claim 13 (depends on 10) The apparatus of claim 10, further comprising the step of exposing the waste to direct current from at least two electrodes, wherein the polarity of the electrodes is periodically reversed, thereby removing impurities from the waste. ### Claim 14 Apparatus for deodorization of livestock waste, comprising: (a) a tank containing livestock waste to be deodorized; (b) a source of atmospheric air; (c) a source of ultraviolet light; and (d) a magnet; (e) wherein air from the source of atmospheric air is passed by the source of ultraviolet light while simultaneously being exposed to magnetic flux from the magnet, thereby creating a plurality of multivalent oxygen ion allotropes; and (f) apparatus for delivering the atmospheric air containing multivalent oxygen ion allotropes to the livestock waste, thereby reducing odor, (g) futher comprising a control system. ### Claim 15 (depends on 14) The apparatus of claim 14, wherein the control system controls the source of ultraviolet light, based on the signal from the float valve. ### Claim 16 (depends on 15) The apparatus of claim 15, wherein the source of ultraviolet light is an ultraviolet lamp, and wherein the control system makes and breaks connections between a ballast box and the ultraviolet lamp. ### Claim 17 Apparatus for deodorization of livestock waste, comprising: (a) a tank containing livestock waste to be deodorized; (b) a source of atmospheric air; (c) a source of ultraviolet light; and (d) a magnet; (e) wherein air from the source of atmospheric air is passed by the source of ultraviolet light while simultaneously being exposed to magnetic flux from the magnet, thereby creating a plurality of multivalent oxygen ion allotropes; and (f) apparatus for delivering the atmospheric air containing multivalent oxygen ion allotropes to the livestock waste, thereby reducing odor, (g) further comprising an air filter between the source of atmospheric air and the source of ultraviolet light. ### Claim 18 Apparatus for deodorization of livestock waste, comprising: (a) a tank containing livestock waste to be deodorized; (b) a source of atmospheric air; (c) a source of ultraviolet light; and (d) a magnet; (e) wherein air from the source of atmospheric air is passed by the source of ultraviolet light while simultaneously being exposed to magnetic flux from the magnet, thereby creating a plurality of multivalent oxygen ion allotropes;
