| titleOfInvention | A method for treating an organic substance |
| abstract | Biomass can be treated chemically in the form of excrement from domestic animals, sludge, waste water loaded with organic matter or the like, in order to separate the fertilizing substances N, P and K and to obtain a fraction d water whose characteristics allow its discharge directly into the ambient environment. To this end, the fresh biomass is treated mechanically and / or chemically, for example by simple precipitation and enzymatic decomposition of the fibrous content, or by extracting gases from the excrement. Chemical reagents are added to the previously treated biomass to cause precipitation of the phosphorus and nitrogen present therein. Reactive agents and nitrogen and phosphorus compounds are reacted to form new compounds capable of precipitating. Any urea content is precipitated together with that of nitrogen and phosphorus. The precipitation of potassium is also caused at the same time as that of nitrogen and phosphorus and before the separation of the biomass into liquid and fertilizing fractions. Said chemical reactive agents include metal ions and organic and inorganic acids. |
