【 摘 要 】

We justified the need to purify wastewater, coming from industrial enterprises, from aromatic compounds using sorption technologies. The objects and methods of our research are described in this paper. In the process of studying adsorption mechanisms of aromatic compounds on bentonites of various modifications in static and dynamic conditions, the basic characteristics of adsorption processes were established. Bentonite, modified by carbon nanotubes after thermal treatment, proved to be the most effective with respect to organic compounds. Three most effective compositions of multicomponent adsorption filter for wastewater treatment from nitro and amino compounds are described. We developed the technological design of a local water treatment plant designed for purifying the wastewater, coming from industrial plants, from aromatic compounds. Multicomponent adsorption filters for wastewater treatment have been developed and patented.
