The main patterns of purification of oily waters using sorption materials based on vegetable and man–made raw materials (sunflower husk, rice husk, polystyrene foam and rice husk) have been established, determining the possibility of effective use of their carbonates in the processes of water purification from petroleum products. It has been established that materials based on carbonates of sunflower husks and rice husks are characterized by the process of absorption of oil and petroleum products by the entire volume. As a result of the conducted research, an optimal carbon-polystyrene sorbent was obtained (21 % rice husk, 79 % expanded polystyrene), which has a high oil capacity in terms of the amount of oil collected at 0 о C. A technological system for local wastewater treatment of petrochemical industries using sorption materials obtained during thermochemical disposal of waste of plant origin has been developed.
