PROCESS METHOD OF LIQUID WASTE OF THE OIL MILLS BY USE OF OZONE (O3) AND IRON SULPHATE (FeSO4).

摘要

For the solution of the problem of polluting of liquid waste from oil mills physical-chemical methods and oxidizing processes have been used until today. The application of the proposed technology is based on the transfer of ozone to the liquid waste of the oil mills in combination with the flocculant action of minimum quantity of iron sulphate. Through it mainly full detoxification of the waste is achieved with simultaneous reduction of the pollution loads of 95 per cent. On the acid environment andin the presence of the organic sub-layer and of a small quantity of iron sulphate the ozone is decomposed as follows: O3 + H2O + Fe - O2 + Fe + OH + OH The roots of hydroxyl are particularly active and they affect very quickly and non selectively the organic compounds creating organic roots. The produced oxygen reacts with these, so, the degradation of the organic material is achieved. These have as a result:1) the production of water suitable for fertirrigation2) the detoxified waste to be used in biological processes of composting with a final product a soil ameliorant of excellent quality.
