PURIFICATION OF WASTEWATER OF CO-PRODUCTION OF STYRENE AND PROPYLENE OXIDE

In a number of industrial samples highly concentrated waste production of propylene oxide and styrene (COD=74-206 g/l), acting at JSC "Nizhnekamskneftekhim" test the effectiveness of different methods of deleting emulsion aromatic hydrocarbons and waste treatment from impurities to replace yagnijoja disposal on the local water purification by subsequent oxidation process residual impurities. It is shown that only steam distillation provides necessary for bioremediation level COD distillate - > 50000 mg/L. the Volume of VAT residue does not exceed 10% of the original waste volume.
