SYSTEM AND METHOD FOR TREATMENT OF SPENT CAUSTIC WASTEWATER

摘要

The present disclosure relates to a process for treating and regenerating a spent caustic solution at ambient temperatures and pressure which includes oxidizing spent caustic wastewater with a hydrogen-peroxide/ozone mixture, supported by a board rang irradiation of the spent caustic wastewater by ultrasound. A range of wastewater treatment techniques may also be included to reach a desired effluent quality level.

主权项

1. A system for treating spent caustic wastewater comprising:
a treatment system including:
a hydrogen peroxide apparatus for mixing hydrogen peroxide with the spent caustic wastewater;an oxygen treatment apparatus for mixing ozone with the spent caustic wastewater;a pH adjustment apparatus for mixing acid with the spent caustic wastewater;an agitator for providing a mechanical catalyst to an output of the oxygen treatment apparatus; an ultrasound apparatus to assist in accelerating chemical reactions between the spent caustic wastewater and the ozone; wherein the combination of hydrogen peroxide, ozone and spent caustic wastewater and the mechanical catalyst produce a treated wastewater.
