Background
Alkaline wastewater (the main component is dibutyl phosphate sodium salt) generated in the process of preparing TBP tributyl phosphate is generally sold as industrial wastewater, and a plurality of effective components can be recovered after the wastewater is treated. When the alkaline waste water is recovered, a stirring tank is generally used, and the dibutyl phosphate and the brine are generated after a proper amount of hydrochloric acid is added into the alkaline waste water. The dibutyl phosphate floats on the brine due to the high specific gravity of the brine, and the dibutyl phosphate is separated from the brine, and then the separated dibutyl phosphate is converted into tributyl phosphate by heating for recovery. Because tributyl phosphate is expensive, if the yield of dibutyl phosphate in alkaline wastewater can be increased, more tributyl phosphate will be produced. The separation of dibutyl phosphate and brine is important, which can not be wasted, and can not be separated completely, thus causing the product phase to be reduced, and therefore, an industrial oil-water separation device needs to be developed.
