ABSTRACT:
The present invention relates to the elimination by biological means of organic waste matter of household or industrial origin or petroleum waste matter. According to the invention the needs in carbon, nitrogen, phosphorus and trace elements of specific aerobic micro-organisms of the waste material to be eliminated and the optimum pH are determined experimentally, the content of each of these nutritive elements in the waste material to be eliminated is analysed, the said waste matter is placed in suspension in water and at least nitrogen and phosphorus contents and the pH of the suspension are controlled by adding elements which contain them so that said contents and pH agree with those necessary to the specific micro-organisms of the said waste matter, and the suspension is aerated. The element added to control the nitrogen and phosphorus contents is mainly constituted by vinasses, of which the nitrogen content is controlled with ammonium nitrate, the phosphorus level with dicalcium phosphate and the carbon level with calcium carbonate. The waste matters to be eliminated are mainly cellulose waste matters and petroleum residues.
