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.
