Abstract
This study developed a modular technological line for producing composite sorbents based on lignocellulosic raw materials intended to intensify the treatment of oil-contaminated wastewater from industrial enterprises. The physicochemical characteristics of wastewater from thermal power plants were investigated, and the technological parameters of mechanical separation, sorption, and desorption processes were substantiated. A comprehensive treatment scheme based on the sequential application of an oil trap and a sorption column was proposed, ensuring a high degree of petroleum product removal from the aquatic environment. It was established that the use of composite sorbents synthesized from local lignocellulosic raw materials makes it possible to reduce the residual concentration of petroleum products to the regulatory level of ≤ 2 mg/L. The developed modular technological line was shown to possess ecological efficiency, the possibility of sorbent regeneration, reduced operational costs, and strong prospects for industrial implementation in wastewater treatment systems.
