of different surfactants on the removal efficiency of heavy metals in sewage sludge treated by a method combining bio-acidification with Fenton oxidation. Four surfactants were adopted such as anionic...-oxidizing bacteria in bio-acidification phase were enriched and cultured from fresh activated sludge obtained from a wastewater treatment plant. It is shown that different surfactants exhibited distinct......
Effect of Y2O3 on microstructure and oxidation of γ-Ni+γ ′-Ni3Al coatings transformed from electrodeposited Ni-Al films at 1 000 ℃ ZHOU Yue-bo(周月波), ZHANG Hai-jun(张海军), WANG Zhen-ting(王振廷... compared with the electrodeposited Y2O3-free γ+γ ′ coatings. The oxidation at 1 000 ℃ shows that the addition of Y2O3 significantly improves the oxidation resistance of the electrodeposited γ+γ ′coatings......
