The invention belongs to the technical field of
nitrobenzene class
wastewater treatment and in particular relates to a process method for advanced oxidation and degradation of
nitrobenzene class
wastewater. The invention solves the problem that the prior method for degrading
nitrobenzene class
wastewater has long time consumption and high cost. The method comprises that: wastewater and
ozone undergo full haptoreaction in gas-liquid
mass transfer equipment; after the haptoreaction, the wastewater enters a
coupling reactor consisting of an ultrasonic
wave field and an
electrolysis field; and nitrobenzene class substances in the wastewater are degraded under the synergistic action of ultrasonic wave and micro-
electrolysis. The device comprises the gas-liquid
mass transfer equipment; a gas inlet of the gas-liquid
mass transfer equipment is connected with an
ozone generator; a liquid inlet of the gas-liquid
mass transfer equipment is connected with a nitrobenzene class wastewater
pool; a liquid outlet of the gas-liquid
mass transfer equipment is connected with the wastewater
coupling reactor; and the bottom of the wastewater
coupling reactor is provided with an ultrasonic wave generator. The process method has the following advantages: the process method has simple process flow and convenient operation, farthest reduces treatment cost and can be applied to various organic industrial wastewater such as
phenol-containing wastewater,
detonator wastewater, dye wastewater, wastewater in a
petrochemical enterprise, detergent wastewater and the like.
