Physical chemical treatment in industrial wastewater system
The method of treating or recycling industrial wastewater by using
extraction, adsorption, ion exchange, membrane separation
technology, gas stripping and the like may be referred to as
physical chemical method. Before industrial wastewater is treated
or recycled by physical and chemical methods, it is generally
necessary to pre-treat to remove impurities such as suspended
solids, oils, and harmful gases in the wastewater, or adjust the pH
of the wastewater to improve the recovery efficiency. Reduce
losses. The physical chemistry methods commonly used are as
follows.
1. Extraction ,method
The water-insoluble solvent is introduced into the sewage, so that
the solute in the sewage is dissolved in the solvent, and then the
solvent is separated by the difference in density between the
solvent and the water. The solute is distilled and recovered by
using the difference in boiling point between the solvent and the
solute, and the regenerated solvent can be recycled. Commonly used
extraction equipment includes a pulse sieve tray tower, a
centrifugal extractor, and the like.
2. Adsorption method
A method in which one or more substances in sewage are adsorbed on
a solid surface by a porous solid substance. A commonly used
adsorbent is activated carbon. The method can be used for adsorbing
toxic substances such as phenol, mercury, chromium, cyanogen, etc.
in sewage, and also has functions of color removal and
deodorization. The adsorption method is currently mostly used for
advanced treatment of sewage. Adsorption operations can be divided
into static and dynamic. Static adsorption, operation under
conditions where sewage does not flow. Dynamic adsorption is an
adsorption operation carried out under sewage flow conditions.
Dynamic adsorption operation is often used in sewage treatment.
Commonly used adsorption equipments include fixed bed, moving bed
and fluid bed.
3. Ion exchange method
The solid matter is used to remove certain substances in the
sewage, that is, the ion exchange of the ion exchanger is used to
replace the ionized substance in the sewage. With the development
of the production and use technology of ion exchange resins, in
recent years, in the recovery and treatment of toxic substances of
industrial sewage, due to good effect and convenient operation,
certain applications have been obtained.
The ion exchangers used in sewage treatment are two types of
inorganic ion exchangers and organic ion exchangers. The
selectivity of the resin must be considered when treating
wastewater by ion exchange. The ability of the resin to exchange
various ions is different. The size of the exchange capacity
depends primarily on the size of the affinity (also known as
selectivity) of the various ions for that resin. At present, the
ion exchange method is widely used to remove impurities in sewage,
such as copper, nickel, cadmium, zinc, mercury, gold, silver,
platinum, phosphoric acid, organic matter and radioactive
substances in the sewage.
