MATHEMATICAL DESCRIPTION OF THE PROCESS OF SORPTION TREATMENT OF WASTE WATER OF CHEMICAL PRODUCTIONS

The article presents the results of experimental studies and a mathematical description of the process of sorption treatment of wastewater from phosphorus production and oil refining from mineral impurities and petroleum products.Experimental studies of sorption treatment of waste water from petroleum products and mineral components were carried out on a laboratory installation with program control of the flow rate of the test liquid 1-4 l/min, in the temperature range of 20-700 C. To develop a mathematical model, we used graphical dependences of experimental and theoretical data that reflect deviations in the degree of recovery of hydrocarbons from wastewater during adsorption. The calculated Fisher criterion is less than the found table value, which characterizes the adequacy of the obtained dependencies.

The analysis of three-dimensional graphic data of wastewater treatment of phosphorus production from the content of impurities P₂O₅, CaO and Al₂O₃ showed that the maximum value of the degree of purification of more than 60% is achieved at a pH of 4.4-4.6.

The obtained data of experimental studies of sorption treatment of oil refining wastewater from oil product impurities are most effectively carried out at a temperature of 40 °C and the flow rate of the test liquid is 2.5-3 l/min, which provides a recovery rate of up to 99.5%.
