Centrifugal extraction machine processing waste water containing phenol sodium hydroxide effect on the rate of removing phenol
At home and abroad used in the recovery of waste water containing phenol phenol method of main steam method, adsorption method, but these methods can only be part of the recovery of phenol.
According to the characteristics of the waste heat temperature is higher, after porcelain ceramic industry in line with the purpose of saving energy, as soon as extraction solvent extraction using centrifugal extraction machine to process waste water containing phenol, in which sodium hydroxide reaction, then distilled the phenolics removal and recovery of waste water.
The method to deal with short process, simple operation, convenient, and can achieve a higher rate of removing phenol and recovery.
Here introduces centrifugal extraction machine processing waste water containing phenol sodium hydroxide on the rate of removing phenol.
centrifugal extraction machine processing waste water containing phenol sodium hydroxide on the influence of the rate of removing phenol: with the increase of dosage of sodium hydroxide, phenolic substances in waste water recovery rate increase, when joining the quality of the sodium hydroxide is about 0.
75 g, phenol recovery rate reached 90%, since the increase of sodium hydroxide dosage on the recovery ratio of phenol.
