The patent application is related to the development of the treatment of the wastewaters from urban or hospital treatment plants with high risk of antibiotic contamination and implicitly with high risk of generating antibiotic resistance genes. The invention consists in the use of natural or synthetic zeolites or more complex mixtures additionally containing absorbent components such as activated carbon, mesoporous silica or active components such as photocatalytic active nanoparticles: TiO2 or ZnO for the degradation of the adsorbed antibiotics. The proposed technology assumes that in the final stage of the treatment, the resulting water is additionally passed through a basin loaded with the aforementioned adsorbent system and thus the antibiotics are adsorbed/degraded without being discharged into the nature. In this way, the microorganisms in the emissary are not exposed to antibiotics, at a sub-therapeutic level enough to induce the development of resistance. Given the alarming level of resistance of microorganisms to antibiotics, this technology is especially necessary in the case of treatment plants of antibiotic factories (and not only), hospitals (and especially infectious plants), livestock farms, etc.
