placed in the same room at the industrial site, not larger than 6X6 meters [70].<br />

Formed after the recycling of concentrated sludge containing heavy metals may be sent for<br />

further processing at specialized enterprises.<br />

The equipment for the elimination of organic liquid wastes are encouraged to use the installation<br />

of high-temperature oxidation, as described in detail in section 4 of this report (MIN and MNO).<br />

The composition of the flow of the elimination of liquid mineral waste includes technological<br />

equipment used for the treatment of industrial effluents from heavy metal ions. This equipment is<br />

offered to use galvanokoagulyator to host training retreat [71].<br />

In galvanocoagulator as the anode can be used by waste metal - steel shavings, sawdust,<br />

cutting. As the cathode is used coke breeze mass 4-10 times less than the anode material. Value<br />

of feed material is 4:1.<br />

When cleaning galvanokoagulyatsionnoy formed ferromagnetic slurry containing crystalline<br />

ferrite heavy and non-ferrous metals: CuO * Fe2O3, ZnO * Fe2O3, NiO * Fe2O3, FeO *<br />

Cr2O3. The compounds according to available estimates and have biotesting IV class of danger,<br />

do not dissolve in solutions of acids and alkalis. In addition, they can be used as a flux in the<br />

manufacture of ceramics and additives in a red brick, in irresponsible casting. In addition, the<br />

sediment has hydrophobic properties, can therefore be used as the underlying insulating layer on<br />

landfills.<br />

Node preparation of waste is a stop-control apparatus with capacitive equipment and is designed<br />

to generate the required pH, which provides full use ferropulpy for the formation of iron<br />

extractable heavy metals.<br />

Realization of this production equipment will eliminate the need for gas cleaning system, as gas<br />

bubble in the process galvanokoagulyatsii happens.<br />

In the process stream destroy any liquid waste (emergency treatment of waste) by precipitation<br />

of heavy metal ions through the formation of insoluble forms, or adsorption on the surface of the<br />

chemical (biological) absorber.<br />

In this case, since the flow is implemented as a first step to reduce the negative effects of heavy<br />

metals on the environment, the used process equipment includes a set of simple technical<br />

means:<br />

tank for storage of reagents or sorbents;<br />

dosing of reagents (sorbents) in a container of liquid waste;<br />

mobile mixing device;<br />

capacity for peretarivaniya waste from leaking tanks;<br />

nozzle for extracting waste from leaking tanks;<br />

nutsch filter and vacuum pump;<br />

container for temporary storage of sediment.<br />

Technological process reduces the deposition of heavy metals from the waste chemical (injection<br />

of reagents) or physical (the introduction of the sorbent) method.<br />

In chemical deposition method from the waste [72], containing heavy metals by the selection of<br />

the stoichiometric amount of precipitating hydroxides followed by dissolving the filtered<br />

sediment in excess of the precipitant.<br />

Thus, under the influence of the stoichiometric amount of lime, heavy metals, main group (Ni,<br />

Co, Cu, Cd, Fe) and an amphoteric group (Zn, Pb, Sn, Cr, Mo, etc.) go to precipitate as<br />

FINAL REPORT for Contract No. CS-NPA-Arctic-13/2009 of December 01, 2009 within the framework of pilot project Development<br />

of Technology of clean up of the area of Decommissioned Sites of The Russian Federation Ministry of Defense in the Arctic by the<br />

Example of Alexanra Island of Franz Josef Land Archipelago from Hazardous Waste<br />
