Method for treating wastewater from nitrogen group in the Murmansk region

The problem of mining enterprises wastewater treatment has not lost its relevance over the past decades. The paper presents the results of laboratory studies on the nitrogen group compounds removal from the wastewater of an Arctic iron ore enterprise using various sorbents: zeolite, sishtof, thermovermiculite. The prospects of using geochemical barriers made of zeolite and vermiculite for the enterprise wastewater treatment are shown. The possibility of using spent vermiculite enriched with nitrogen as a prolonged action fertilizer as part of remediation measures was proposed.
