Study On The Treatment Of The Oily Wastewater From Refinery Factory By Microwave Radiation And Electro-Floatation

The feasibility and processing conditions on the treatment of the oily wastewater from the refinery factory by microwave radiation and electro-floatation process were investigated in this paper. The optimnm operation parameters in the process of microwave radiation were suggested, such as the amount of the flocculant, microwave power and the time of microwave radiation. The optimnm operation parameters in the process of electro-flotation were also suggested, such as plate electrode material, plate electrode connecting, pH, the current intensity and flocculant addition. The experimental results showed that it brought about a striking effect and had the merits of simple equipments and processing, low cost, low pollution or without secondary pollution when microwave radiation and electro-flotation was used respectively to treat the oily wastewater from the refinery factory.
