Abstract：

Porous lead zirconate titanate (PZT) ceramic membranes were fabricated with starch as pore-forming agent. Effects of starch content on microstructure and piezoelectric performance of membranes were studied. The results show that the porosity and pure water permeability of the ceramic membrane increase with the increasing of the pore-forming agent, while the mechanical strength and piezoelectric properties are gradually decreased. When 2.5% pore-forming agent is added, the water permeability of ceramic membrane is 2250 L·m-2·h-1·MPa -1, the pore size is about 500 nm, and the resonance amplitude signal is 42 mV. The optimized PZT membrane was applied in oil-in-water emulsion wastewater purification to test its self-cleaning performance. With in-situ ultrasound, the stationary permeability of PZT membrane was 55% of its initial value while this value was 37% as opposed to without. This demonstrated the self-cleaning performance of the ultrasound generated by PZT membrane.
