Popis:	Keywords: SBRmethod, Wastewater from production of PolyTHF, extraction method Abstract: The wastewater from the production of polytetrahydrofuran (PolyTHF) was treated with union between of the extraction method and SBR method. The results showed that at 25°C, phase ratio of 1:1 and equilibrium time of 40min, using chloroform as extraction agent, CODCr removal rate could reach as high as 75%. After the treatment of wastewater was treated by SBR method, which meet the national level of discharging standard, CODCr removal could reach at 100mg/L.
