Abstract

La presente invención se relaciona con un proceso químico en el que se emplea una concentración determinada de cloruro de sodio y cloruro de calcio, mezclado en concentraciones iguales y aplicado sobre las heces fecales o excretas, bien sea de origen animal o humano, para obtener un compost de residuos sólidos microbiológicamente inocuos, en donde el proceso se caracteriza porque permite el mejoramiento de suelos por medio del uso de una cantidad predeterminada de cloruro de sodio (NaCl) que permite aumentar los iones de sodio de las heces, junto con una cantidad predeterminada de cloruro de calcio (CaCl2) que permite hacer un agotamiento de la humedad o el agua presente en la materia prima, con lo cual se elimina la mayor cantidad de microorganismos presentes en las heces modificando el pH del medio y poder así provocar la lisis de la célula bacteriana. La presente invención también está dirigida a una composición química que es usada en el proceso químico previamente definido, en donde dicha composición se mezcla con la materia prima proveniente de las heces y permite obtener el producto tipo compost para el uso en suelos.The present invention relates to a chemical process in which a certain concentration of sodium chloride and calcium chloride is used, mixed in equal concentrations and applied to feces or excreta, either of animal or human origin, to obtain a compost of microbiologically safe solid waste, where the process is characterized in that it allows soil improvement through the use of a predetermined amount of sodium chloride (NaCl) that increases the sodium ions of feces, along with a predetermined amount of calcium chloride (CaCl2) that makes it possible to deplete the moisture or water present in the raw material, which eliminates the greatest amount of microorganisms present in the feces by modifying the pH of the medium and thus can cause lysis of the bacterial cell The present invention is also directed to a chemical composition that is used in the previously defined chemical process, wherein said composition is mixed with the feedstock raw material and allows the compost product to be obtained for use in soils.
