Abstract
The invention relates to a method for treating waste water containing phenol, in particular to a method for treating waste water containing phenol of a generator gas station. The technical procedures are as following: waste water containing phenol and generated and collected by a gas station is filtered, and suspension substances, tar oil and other impurities in the waste water are removed; the waste water is pumped into a water leg of the gas station by a pump, and the partial heat in the gas gasifying process is used for gasifying the waste water; vapor after the low boiling-point benzene and phenol substances in the waste water containing phenol are gasified enters the bottom of a gas generator, and high boiling-point benzene and phenol substances are not gasified and left in the water leg to be discharged to a tar oil pool to be sold with tar oil with the regular dirt discharge of the system. The method for processing the waste water containing phenol of the gas station is the organic combination of residual heat recovery, the circulation use of waste water and the treatment of sewage containing phenol, and effectively realizes the energy saving and the discharge reduction of the gas station.
