Liquidation of Oil and Petroleum Products Spills Based on Use of NA and CA-Differences of Zeolite

Abstract

The article discusses the use of ecologically and economically practical proved methods of neutralizing the soil ecosystems in Yakutia after emergency oil spills. Experimental studies have been made to develop a new biosorbent based on a natural sorbent. The natural zeolite Na and CA-differences from the Khonguruu deposit (The Republic of Sakha (Yakutia), Russia) is used as a base for obtaining the biosorbent. The necessary typification of zeolite deposits revealed at the stage of exploration, in order to determine the field of practical application of raw materials in the preparation of the field for industrial development. The types of raw materials according to the cationic composition difference are identified: clinoptilolite-heulandite and heulandite. A brief description of the material composition and averaged physico-chemical characteristics of various types of zeolite raw material is given. We present the results of the experimental application of hydrocarbon oxidizing microorganisms (HOM) immobilized on zeolite (clinoptilolite- heulandite series) from the Khonguruu deposit in oil-contaminated soils. It has been established that the obtained biomineral compositions provide a significant activation of petroleum hydrocarbons (HC) biodegradation in the soil. In general, the technology of using zeolite raw materials for cleaning up oil spills from different types of permafrost soils provides a significant ecological and economic effect, thus contributing to the reduction of the time for rehabilitation of disturbed lands and the improvement of the environment in the disturbed territory.
