Potential Pollution Reduction Process of Animal Waste Through the Use of Industrial Waste

摘要

The present invention belongs to the technological sector of waste and waste treatment and refers more specifically to a process of reducing the levels of contaminants of this type of waste, especially the copper, zinc, nitrogen, phosphorus and potassium ions present in liquid waste. swine or other aqueous slurry or solutions, being environmentally friendly, low cost and easy to perform, since it makes use of an industrial waste produced in the extraction of the amethyst stone known as metabasalt. Due to the adsorption properties of the metabasalt particles, this input is capable of adsorbing the free ions of copper (cu2 +), zinc (zn2 +), nitrogen (n), phosphorus (p) and potassium (k) contained in liquid waste. especially pigs. In this way, the time required for the destination of the liquid pig slurry, either for the disposal of the liquid fraction of the slurry or the reuse of the solid fraction of it in crops, is avoided, wasting time and, mainly, significantly reducing the environmental impacts caused by the incorrect disposal of this type of waste in its liquid fraction. Finally, the present invention discloses an environmentally friendly process of reusing the easy-to-perform and inexpensive amethyst stone exploration waste (metabasalto) available from large industries to small farmers.
