In this connection, with regard to the peculiarities of the elimination of spent technical liquids
and oils, located on Alexandra Land, it should be implemented a complex technology. To
implement this technology, it is expedient to highlight the most important stages.
The first stage of technology should include the identification of waste, based on express method
s and their subsequent transfer of two to three industrial sites. In this case, the main goal of the
actions is the formation of waste identified in its qualitative composition according to their
hazard degree. Since most available drums are in poor state, it should be possible to retrieve the
waste in a safe into drums or tanks.
The second stage should be aimed at carrying out the decontamination of emptied containers
(including - transformers and condensers), with further compaction and recycling.
emptied drums must be decontaminated before compaction.
Decontamination of drums from fuel and lubricant residual can be made either by the reagent, or
burning them up Fakel-1M-type installation. Decontamination of containers after removal of
PCB-containing technical liquids is a more complex process.
Based on the analysis of available technologies and methods for decontamination of condensers
and transformers, it is expedient to wash capacitive PCB-containing equipment with vapors of
methylene chloride up to a required level of safety.
According to the system adopted by the developer of technology "Petrohim-technology,
technological scheme includes:
collection of transformers and placing them in a special place;
preheating of each transformer, emptying it at the expense of gravity and the collection of
liquid PCB in a separate tank for disposal;
carrying out the cleaning cycle of the transformer using methylene chloride vapors;
disassembly of the transformer and sorting of components.
It was established that in course of cleaning methylene chloride vapors, metal parts inside the
transformer are cleaned to such an extent that they are not considered hazardous waste and can
be recycled without no difficults;
wooden details, cardboard and paper, which may still contain a residual amount of PCB, are sent
for incineration or simple burial, if the concentration of the remaining PCB complies with the
environmental requirements for disposal (PCB content less than 50 mg / kg).
All techno-economic and environmental parameters of the disposal of persistent organic
pollutants were confirmed on a laboratory installation using natural samples of PCB-containing
wastes.
Summarizing the above, some preliminary conclusions should be made.
First, with account for data available for the first phase of work the most appropriate technology
of elimination of waste liquids and oils is a complex of interrelated steps, including the stage of
identification and subsequent collection of liquid waste, decontamination of emptied containers
and the elimination itself of the collected spent oils and technical liquids.
Second, the most efficient decontamination of capacity equipment from PCB is that using
reagents. The technology using methylene chloride vapors is the most appropriate one. It is
