Extraction equipment processing waste water containing phenol extraction method is one of the physical and chemical wastewater treatment.
Using the extraction equipment as well as the extraction agent, through the extraction function make the purification of wastewater containing phenol method.
according to a solvent for the different materials have different solubility properties, soluble in some pollutant in the wastewater can be fully or partially separated.
To cic with does not dissolve in water or wastewater is difficult to dissolve in water solvent (
Extraction equipment, processing waste water containing phenol extraction method can make the dissolved some pollutant in the wastewater,
The interface between the two liquid phase extraction agent and waste water turn into extraction agent.
extraction manipulation according to the processing objects of state can be divided into solid -
Fluid extraction, liquid -
Extraction equipment processing waste water containing phenol extraction method belongs to the latter, its control process: 1) mix, even if the waste water and extracting agent maximize contact (2) separation, even if the separation of light and heavy liquid;
(3) the extractant regeneration, namely after the extraction, separation by extraction, extractant recycling and reuse.
extraction equipment processing waste water containing phenol extraction method in the selection of extraction agent should satisfy: (1) to extract the solubility of big, for small water solubility (2) and the proportion of extract, boiling point, there is enough difference is (3) with chemical stability, does not react with the extract
4. Easy to recycle and regeneration (5) the price is low, the source is enough.
This is often used in relatively high concentrations of phenol or containing aniline acetate, benzene, and other industrial wastewater treatment.
