Abstract

Sorption is currently a promising method for purifying wastewater from organic and inorganic substances. The authors have developed a technology for obtaining a granular composite sorbent (GCS), on the basis of large-tonnage production waste - tobacco dust. However, as a result of sorption purification of highly concentrated wastewater from food industry enterprises, a significant amount of waste sorbent is formed, the regeneration of which is economically inexpedient. This article presents the laboratory studies’ results, on the basis of which methods of GCS disposal were developed, exhausted its sorption resource for the new products’ manufacturing in construction industry.

In recent years, the problems associated with the water basin pollution have become aggravated
One of the industries characterized by the formation of highly concentrated waste water (WW) are the tobacco industry enterprises that are a part of food industry for which the method of sorption additional purification of substandard waters is the most economically justified and effective [3,4,5]

Summary

Introduction

The problems associated with the water basin pollution have become aggravated. After using GCS sorption-filtering material for WW post-treatment enterprises of the tobacco industry in the Russian Federation from pollution, the concentration of which is many times higher than the permissible values even after electrochemical treatment (see Table 1), it is proposed not to regenerate it due to the economic inexpediency of this process due to the need to use a significant amount of water, but to recommend directions by the alternative methods GCS waste disposal as: a porous addition to the clay mass in the ceramic products manufacture [10,11,12] and one of the components of dry building mixtures for flooring [13,14,15]. Permissible concentrations, in accordance with the Administration Decree of Volgograd No 3229 from 24.10.2011
