Therefore, the preservation of industrial sites and storage sites containing sovtol and other
PCB-containing liquids must be carried out chemical and mechanical methods that worked
well in the Far North.
The chemical method is based on the transformation of toxic hydrocarbons into non-toxic
compound or the curing of toxic substances in the form of a gel or solid. Drug use "Ekonaft
(oxides of mineral sorbents) with a high sorption capacity for chemical decontamination and
neutralization of toxic neftemasloothodov will allow them to adsorb uniformly to give a dry,
persistent storage powdery substance consisting of tiny granules, which are microparticles
neftemasloothodov enclosed in calcareous shell capsules, regularly spaced in the mass of the
product. Method is recommended for cleaning contaminated soil on the ground only for
technical purposes.
In the mechanical methods used to collect oil in the liquid (unbound form) is produced by the
"mud" pump (sludge tank), allowing to collect any oil viscosity and mechanical impurities
(eg, soil). It is recommended to use domestic vacuum-type setting - «VAU-1», «VAU -2»
with a load capacity of 200-300 liters. If you can not collect toxic oil from the ground using a
"collecting plants" must use the method of fixation (immobilization), a toxic agent
(vitrification, cementation, melting the ground, encapsulation).
Grouting should be considered as part of technology-specific methods of decontamination and
disposal of soil with a relatively low PCB content. In particular, it is actually possible to build
on contaminated soil using cement building materials with biocidal properties.
