Ecological evaluation of effluents from meat enterprises shows that processing of agricultural production is accompanied by consumption of large amount of water which is saturated with organic substances and a number of biogenic elements (phosphorus and nitrogen compounds) during its industrial utilization. Effectiveness of natural sorbents klynoptylolit use for removing of such pollutants as ammonium and phosphate ions and protein fractions was theoretically substantiated and proved. Adsorptive capacity of sorbent concerning above mentioned pollutants during investigation of one-component system sorption was established; and influence of contamination of drains on equilibrium and speed of adsorptions during research of two- and three-component model systems was determined. Equation of isotherms of adsorption for one-, two- and three-component systems, based on the law of Henry, was proposed. Equilibrium values of adsorptive capacity of sorbent were investigated and kinetic curves were built, which made it possible to establish necessary time for removing of pollutants from drains. A mathematical model of pore-diffusion sorption is presented and diffusion coefficients: D*NH4+= 2.84×10-11 m2/s, D*P2O5= 2.92×10-10 m2/s, and D*alb. = 6.54×10-13 m2/s, are determined. The efficiency of worked out sorbent application as fertilizer was experimentally proved.
