Solution of Environmental Issues of Wastewater Treatment by Means of Design of Sorbent Based on Zeolite

Abstract

The results of the presented complex of studies made it possible to determine the main sorption properties of zeolite-containing raw materials of Transbaikal, which in its turn, determined the setting of the experiment to dtudy the regularities of sorption extraction of petroleum products and heavy metals ions from industrial sewage of railway transport enterprises. There were considered different options of natural zeolite’ modifications of Kholinsky deposit for the creation of sorbents possessing high sorption activity in relation to petroleum products and heavy metals ions. As modifiers are selected high-organo-silicon compounds – hexamethyl disilazane [(CH₃)₃Si]₂NH and tetraethoxysilane (С₂H₅O)₄Si, promoting hydrofobization of surface. Aside from that, as modifier be used sulfur polymer obtained from waste of ethylchlorhydrine production. This will solve simultaneously two problems: recycling of waste and wastewater treatment, which is beneficial from economic point of view.
