| Abstract: | Wastewater from acrylic fibre production with two step process contains a lot of low polymers, acrylonitrile and sodium thiocyanate etc. and CODCr of the wastewater is high. The processes including micro-electrolysis, biomembrane filtration and biomembrane contact oxidation were employed to treat the water. The data of the treated water were as follows: CODCr< 750 mg/L, acrylonitrile < 5 mg/L,sodium thiocyanate < 35 mg/L, pH=6～9. The treated water meets the requirements of further treatment. |
