(57) Abstract The large quantity it was melted and/or in the consistent processing method of purifying industrial draining and city draining which include the organic matter of suspension state, in order to mineral to convert most of the organic matter, draining it is the method inside the wet smothering reactor (10) of processing at least under existing of one oxidation gas gas phase (13) and by mainly forming the solubility residual organic matter and the liquid phase (12) which includes the solid phase of the mineral of suspension state. The liquid phase which it occurs with the reactor is separated the liquid hard, the solid phase is separated, that the solid phase (26) which is separated part is recycled at least inside the wet smothering reactor. In addition, the catalyst and/or the acidification medicine in order to acidify the solid phase of the part which was recycled may be added as other execution example of this method. Furthermore, equipment operating and the half it may operate continually continually.
