BIOPREPARATION FOR PURIFYING WATER FROM HYDROCARBON CONTAMINANTS

摘要

The invention relates to agents for removing organic contaminants from environmental media and is intended, in particular, for the biological purification of water contaminated with petroleum and petroleum products. The biopreparation for purifying water from hydrocarbon contaminants, comprising a porous carrier of biologically active microorganisms and containing the glass-like metaphosphates KPO 3 , Mg(PO 3 ) 2 , Ca(PO 3 ) 2 , as well as Al 2 O 3 and hydrocarbon-decomposing microorganisms, additionally contains TiO 2 and inorganic nitrogen-containing compounds in the following component ratio (wt%): KPO 3 - 20-40; Mg(PO 3 ) 2 - 5-10; Ca(PO 3 ) 2 - 30-50; Al 2 O 3 - 5-10; TiO 2 - 1-5; KNO 3 - 1-3; NH 4 H 2 PO 4 - the remainder. The result is an increase in the effectiveness of the biopreparation in purifying water from hydrocarbon contaminants and an increase in the active life of the biopreparation.
