Development of the integrated model of ecologically safe utilization of phosphogypsum in environmental protection technologies

Abstract

This paper focused on the development of scientific and theoretical foundations for conducting research on the environmentally safe disposal of phosphogypsum in environmental protection technologies. The biochemical direction of technological solutions for the phosphogypsum treatment as a mineral raw material to stimulate the development of the necessary ecological trophic groups of microorganisms is developed. The methodological approach was formalized in the ecological-synergetic concept of phosphogypsum wastes using. At the same time, paper focused on the interconnection in related spheres of the use of mineral carriers based on phosphogypsum with the integration of individual technological solutions in the system of protection of aquatic ecosystems, atmospheric air and the processes of restoring contaminated soils. The biochemical conversion will be able to provide efficient purification of environmental components using phosphogypsum and products of its processing as supply medium in biotechnological environmental protection systems. In the process of phosphogypsum conversion, a mineral carrier is obtained for the immobilization of microorganisms in the technologies of aquatic ecosystems protection, biochemical gas purification from sulfur compounds, in remediation processes of contaminated soils. The scheme for the determination of ecologo-microbiological parameters was developed for estimation of the effectiveness of using phosphogypsum as a mineral substrate by different groups of microorganisms in environmental protection technologies.
