    Abstract: The invention relates to a photocatalytic treatment system for reducing the nitrogen content in livestock waste comprising the following steps: • separation of the gross solids from the sewage as is by filtration; • temperature control of the separated sewage at a preset temperature; • aeration with air flow; • contact of the aerated sewage for a preset time with a photoactive phase composed of a modified semiconductor; • exposure of the sewage to light radiation. The invention also relates to a photocatalytic treatment plant for reducing the nitrogen content in livestock waste comprising: • a reactor (1 ) provided with light radiation generating means (2) and photocatalyst means composed of a modified semiconductor, suitable to contain for a preset time the sewage to be treated, containing nitrogen in organic form, previously separated from the gross solids by means of filtration; • means (3, 4, 5) for the insufflation of air into the reactor; • heat exchanger means (6) connected to heat generating means (7); • discharge means (8, 9) of the nitrogen and of the gaseous compounds; • feed (10) and discharge (11) means of the sewage to be treated.
