Preparation of catalytic ozonation membrane and analysis of humic acid removal mechanism
摘要
Abstract
To further improve the effectiveness of membrane process and reduce membrane fouling, catalytic membranes were prepared with the phase transfer method in order to realize microfiltration coupling and catalytic ozonation for micro-polluted water treatment. The sol-gel method was used to prepare TiO2,and nano-sized particles at different heat treatment temperatures were added into the casting solution. The characteristics of catalytic membranes were investigated with X-ray diffraction (XRD),scanning electron microscopy(SEM),water flux,porosity,and contact angle. The membranes catalytic efficiency and membrane separation processes were also investigated. Rutile TiO2 (namely PVDF/ TiO2-600) membrane achieved above 70% and 65% removal rate of humic acid (HA) and total organic carbon (TOC),respectively. The novel catalytic membrane exhibited good catalytic ozonation activity and anti-fouling property for HA removal,which demonstrated that catalytic ozonation membrane an emerging technique for water treatment.关键词
