Abstract

Purification of wastewater from petroleum products is an urgent problem for the Tyumen province as an oil and gas region. The use of natural materials is actively studied in the technologies of sorption cleaning which is the main method for oil pollution removal. One of these new technologies is the wastewater treatment method with the use of probiotic agents. The purpose of this research is to study the effect of probiotics on the degree of dissolved petroleum products extraction from aqueous solutions by phytosorbent (pine sawdust). The photometric method of liquid analysis was used as a standard method of research. As a result of the sorption process study, it was found that the concentration of petroleum products decreased faster and to a minimum value (by 48.68%) when filtering samples through a layer of sawdust soaked in a probiotic solution, which is 2 times more effective than pure sawdust. The sorbent used is environmentally friendly.

Highlights

The most significant natural resources of the Tyumen region are oil and timber
The results of the study of thesorption purificationof an aqueous solution in a static mode are presented in Table 1, which shows that the most pronounced effect is given by a complex sorbent consisting of sawdust impregnated with a probiotic solution
Based on the results of the study of the process of the PipPlusWATER probiotic agent influence on the efficiency of sorption purification, the following conclusions can be drawn: 1. The combined use of pine sawdust with a probiotic increases oil absorption by 2,014 times compared to the use of pure sawdust

Summary

Introduction

The most significant natural resources of the Tyumen region are oil and timber. The oil and gas industry is one of the most important segments of the regional economy and the main source of pollution. The fuel industry accounts for 86.4% of the regional industrial output. 200300 million tons of oil and gas condensate and more than 500-600 billion meters of natural gas are produced annually [1]. The fuel industry is the main source of environmental pollution with its oil and petroleum products. The timber industry is one of the promising sectors of the Tyumen region’s economy. The value of the manufactured products exceeds 4.96 billion rubles according to the data of the timber industry complex enterprises (Tyumen region). The timber industry has been found to be inefficient in waste management: only 15% of total wood residues resulting from processing are recycled [2]
