Hyvlyud A. The extermination of pollutants of wastewater dairy industries by sorption methods

The thesis is dedicated to providing environmental safety of groundwater contamination by wastewater treatment of dairy industries by sorption methods. Sorption technology is proposed as a method of wastewater treatment of dairy industries, based on the use of Sokyrnytsky's deposits of natural zeolite. The dissertation's researches are based on dairy wastewater systems, existing modern methods of treatment and basic methods of sorption as the most economically and environmentally beneficial method of wastewater treatment. Methods of physical and chemical analysis of the structure of natural zeolite before and after adsorption, frame structure, porosity and pore size, the presence in the structure of the zeolite carbon radicals after adsorption were investigated. At first time the static activity on natural zeolite of а - oxypropionic acid was studied. The static activity on natural zeolite of protein (albumin) and phosphate compounds was experimentally investigated. At first time the sorption of phosphorus compounds with different degree of substitution and hydrogen adsorption isotherms was obtained. For all cases pH value was definded and was shown that during sorption the value increases. The research sorption of kinetics а - oxypropionic acid and protein revealed two areas of process: external and internal diffusion. Experimentally the dynamics of the process of wastewater treatment fixed bed of natural zeolite was studied. A technological scheme of wastewater treatment of dairy industries was offered.
