预氧化强化混凝沉淀-超滤处理微污染水
Enhanced coagulation-ultrafiltration by pre-oxidation for micro-polluted water treatment
摘要
Abstract
Effects of pre-oxidation on coagulation-ultrafiltration for micro-polluted water treatment were studied with respect to effluent water quality and membrane fouling. Oxidants, namely KMnO4, O3 as well as their combination were tested, respectively. Based on analyzing the three-dimensional fluorescence spectroscopy of organic matter in effluent water and filter resistance of PVDF membrane, the underlying mechanisms of the enhanced performance were discussed. The results showed that the combination of KMnO4 with O3 could significantly improve the organic matter removal by coagulation using polyaluminum chloride, especially for the humic substance. As a result, the water quality of the ultrafiltration permeate was improved, and the membrane fouling caused by the absorption of humic substance in membrane pores was consequently reduced.关键词
