hydroxides and hydroxy.
When exposed to the resulting solution of excess alkali heavy metals, the core group moving in
the sediment and can be separated from the solution by filtration.
From a solution of an amphoteric metal hydroxo group selection in the form of their hydroxide
precipitate is due to the introduction of sulfuric acid followed by filtration.
On physical vapor deposition method of waste [73-76], containing heavy metals by the selection
of metal ions on the surface of the sorbent. As a sorbent can be used various compounds that
meet the objectives of the operations (biosorbent from native or inactivated biomass composite
sorbents based on strongly acidic cation exchanger KU-2-8, and iron hydroxide (III),
kompleksooborazuyuschie sorbents modified material based on iron-manganese nodules,
humates ammonium, sodium or potassium, etc.).
Agents (sorbents) are introduced into the container with liquid waste and mixed to increase the
efficiency of extraction of heavy metals.
After sorption of heavy metals from solution by exudation on nutch-filter, followed by its
peretarivaniem in special containers.
Precipitation received during the implementation of the chemical or physical methods, and
containing the insoluble forms of metals, can be temporarily stored and subsequently sent for
further processing .
10.2. Options for the implementation of technological solutions
The above basic technological solutions allow us to implement various methods of
disposal of waste containing heavy metals. In Figure 10.2.1 shows the block diagram of the
complex technology of waste treatment and processing equipment, containing heavy metals.
