Abstract

In this study, a desalination procedure has been developed in penicillin G-processing wastewater biological treatment. The procedure is focused on removal of part of organics and the majority of sodium sulfate to decrease the difficulties in subsequent biological treatment. The effects of activated carbon, sodium hydroxide on the process have been carefully measured to enhance the COD removal rate. Based on solubility of sodium sulfate in a methanol-water system and the practical research, antisolvent crystallization process was applied to recover sodium sulfate with an optimal solvent volume ratio. Yield and purity of the refined crystals have finally reached 78.28 wt % and 97.56 %, respectively.
