11.4 Conclusions and recommendations.
Summarizing all the above on the technological project of preservation of objects
containing sovtol and other PCB-containing liquids should draw some conclusions and
recommendations.
Firstly, taking into account the available experimental data on the performance of work, the
most appropriate technology, the elimination of waste liquids and oils, containing PCB, is a
set of interrelated stages, including the steps of: identifying, collecting liquid waste container
and neutralize the liberated stage of immediate elimination (recycling) collected spent oils and
technical liquids.
Second, the neutralization capacity equipment from the PCB, most effectively by way of
neutralizing reagent.
As this method is most appropriate implementation technology with the use of methylene
chloride vapor. Neutralization of the drums and other equipment from residual PCB useful to
carry out reagent method, and spent activated carbon from the site clean exhaust gases
disposed in the installation of high-temperature oxidation.
Thirdly, wood and other combustible waste must be sorted. Waste with high concentrations of
especially dangerous pollutants such as PCB, are due for elimination in high temperature
plants. The remaining unusable wood waste, grind and useful as a fuel or combustible
material to burn a simple to install high-temperature combustion (incinerator) or to install
"Fakel - 1M. Likewise it is recommended to deal with other combustible solid waste,
including rubber and plastic products, paper and cardboard, paper and remnants of clothing
and uniforms, etc. Exceptions should be made of polyvinyl chloride products, which are
burning in the vast majority (not equipped with special systems flue gas) incinerators is
unacceptable. This kind of waste must be burned in the installation of high-temperature
incineration.
Fourthly, it was found that the basic technology of neutralization of hazardous organic
pollutants such as PCB is high temperature oxidation (combustion) with afterburner systems
and neutralization of waste gases.
The process of destroying hazardous wastes is most advisable to implement technologybased,
providing for the use as a node in the thermal cracking of a rotary furnace and a plasma
afterburner, as well as 3-stage flue gas cleaning systems on the basis of complex treatment
technologies and automatic control.
Fifth, the preservation of elements of buildings, brick and wood, chemical control in the past
for safety and are not intended to restore and use for its intended purpose, is not provided -
these objects should be destroyed. Concrete and brick secondary materials should grind up to
the size and gravel used for road bank filling in their accomplishment, as the rubble is in the
manufacture of light weight concrete coatings storage, recreation, other sites etc.
Sixthly, the soil in field work on o.Alexandra Island is a mixture of various size fragments,
mostly of basaltic origin, sand and very small amounts of organic residues. Therefore, oil
pollution is not included in the structure of the soil, but remains in the form of spots and
inclusions in various mineral residues.
