One of the most common types of ecotoxicants is oil products - unidentified group of oil hydrocarbons and products of its processing. In this regard, the development of technology for obtaining new highly efficient and inexpensive sorbents for wastewater treatment from oil products (including industrial waste) is an urgent problem. In this paper, the technology of wastewater treatment includes the use of composite sorbents based on tails-waste of Uchalinsky (UW) and Buribaevsky (BW) mining and processing plants (MPP), mica quartzite (MQ) of the Baymak field and montmorillonite clay (MC) and sodium humates (SH) obtained from waste of Tulgan brown coal. Using these sorbents, we investigated the efficiency of these sorbents in model wastewater treatment contaminated with oil from the Vozeyskoye oilfield of LLC Usinsk Neftegaz and real wastewater of “Bashneft” Ufa Oil Company. It is shown that the efficiency of treatment and the rate of adsorption of model wastewater containing oil products (8-50 mg/dm3) increases in a number of sorbents MQ < BAU < BW (UW) + MC < BW (UW) + MC+SH (BAU is a comparison sorbent - activated carbon) and reaches a maximum for MPP coated with SH. For real wastewater containing oil products of Ufa refinery (3-625 mg/l) adsorption activity increases in the number of MQ < MQ + MC < BW + MC < UW + MC. Thus, the most effective sorbents for real and model wastewater containing oil and oil products are sorbents based on waste from Uchalinsky MPP in the composition of MH (degree of purification 96.1 %), as well as sorbent: waste UW (BW) + MC modified SH (98.1 and 98.2 %, respectively).
