Abstract
- Membrane coupling with electrochemical processes has proven to be an effective way for wastewater treatment. However, it still suffering from high energy consumption and low operational stability. Three different forms nanosheet-MoO<subscript>3</subscript> were prepared by hydrothermal synthesis method via adjusting various additives to ammonium heptamolibdate. MoO<subscript>3</subscript> loaded porous Ti membranes was employed as anode to constitute fixed-bed electrocatalytic reactor (FBER) for synthetic dye wastewater treatment to overcome the drawback of three different forms. The electrochemical properties of MoO<subscript>3</subscript>/Ti membranes were investigated, results showed that the MoO<subscript>3</subscript>/Ti membranes with hexadecyltrimethylammonium bromide (CTAB) additive exhibited the best electrochemical performance. Meanwhile, three MoO<subscript>3</subscript>/Ti membranes were used to constitute FBER for 100 mg l<superscript>−1</superscript> MO wastewater treatment, the MO and COD removal rate of MoO<subscript>3</subscript>/Ti without additive, MoO<subscript>3</subscript>/Ti with CrCl<subscript>3</subscript> additive and MoO<subscript>3</subscript>/Ti with CTAB additive were 78.6% and 65.3%, 83.2% and 72.9%, 90.3% and 81.6%, respectively. Furthermore, the energy consumption of MoO<subscript>3</subscript>/Ti with CTAB additive was only 0.76 kWh·kg<superscript>−1</superscript>·COD. After 3 repeated stabilities experiment of 12 h MO wastewater treatment, the removal rate of MO and COD remained above 97.2% and 88.6%. In sum, the FBER exhibits a great potential in the dye wastewater treatment with high efficiency and excellent stability. [ABSTRACT FROM AUTHOR]
