’nan 250116, China) Abstract: Micron cell porous Al with high strength was fabricated by the vacuum-pressure sintering-dissolution processing. The preparation processing, strength and filtration..., the micron cell porous Al possesses a good filtration property and a higher specific compression collapsing strength. Key words: porous Al; micron cell; strength......
through a combined coagulation-membrane bioreactor (MBR) processes. The index on wastewater’s chemical oxygen demand (CODCr), biological oxygen demand (BOD), color, turbidity and so on was measured...) concentration are almost zero. It’s shown that it’s feasible to use MBR to treat the dyeing and printing wastewater. Key words: dyeing and printing wastewater; coagulation; membrane bioreactor (MBR......
