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 />
