A Study on Salt Effect on Treatment of Oily Wastewater Using Microwave Radiation

Abstract:

The treatment of oily wastewater by microwave radiation is highly-efficient, low contaminative. In order to improve the effect of processing oily wastewater with microwave radiation, the influence of the ionic property, the ionic valency, the ionic concentration and microwave parameter are investigated by experiment. The results show that inorganic salt promotes demulsification under microwave radiation condition. The lower the ionic valency is, the better the deoiling effect is. The deoiling rate increases in a certain range with concentration of inorganic salt increasing, and it also has the optimum microwave parameters. When oily wastewater is disposed by microwave radiation after adding inorganic salt, the deoiling rate is up to 97.78%
