乔治王岛菲尔德斯半岛火山岩岩石学特征及岩浆成因与演化

菲尔德斯半岛出露一套第三纪岛孤火山岩,包括高铝玄武岩、玄武安山岩、及少量安山岩与英安岩,从早到晚可划分为碧玉山段、玛瑙滩段、化石山段和岩块山段四个岩性段.它们属于同一钙碱性岩浆演化系列,其中高铝玄武岩是其它火山岩的母岩.高铝玄武岩的形成过程可分两个阶段:首先是上地幔楔经过20～25％的部分熔融生成原生橄榄拉斑玄武质岩浆,然后原生岩浆再经40％的矿物分离结晶作用(其中橄榄石占30％,单斜辉石占70％)而分异形成高铝玄武岩浆.

Seed yeast cultivation for salad oil manufacturing wastewater treatment

The mixture of five yeast strains obtained from soil could remove about 85% TOC of oil-rich wastewater in batch test.While the highest MLSS was obtained at an N:C of 1:5,the oil removal decreased with the increase of N:C during yeast sludge cultivation.Ammonium chloride was the best nitrogen source for yeast cultivation from the viewpoint of yeast growth and oil utilizxation.An ammonia concentration of over 1300 mg/L led to mass death of yeast at a pH of 5.The ammonia concentration should be controlled at a level of 1000 mg/L or lower.

Fulvic acid removal by nanoparticle TiO2 using a submerged membrane photocatalysis reactor

The degradation of fulvic acid（FA） by nanoparticle TiO2 in a submerged membrane photocatalysis（SMPC） reactor was studied. In this reactor, photocatalytic oxidation and membrane separation co-occured. The continuous air supplier provided O2 for the photocatalytical reaction and mixed the solution through an airflow controller. The particle TiO2 could automatically settle due to gravity without particle agglomeration so it could be easily separated by microfiltration（MF） membrane. It was efficient to maintain high flux of membranes. The effects of operational parameters on the photocatalytic oxidation rate of FA were investigated. Results indicated that photocatalyst at 0.5 g/L and airflow at 0.06 m^3/h were the optimum condition for the removal of fulvic acid, the removal efficiency was higher in acid media than that in alkaline media. The effects of different filtration duration on permeate flux rate of MF with P25 powder and with nanoparticle TiO2 were compared. Experimental results indicated that the permeate flux rate of MF was improved and the membrane fouling phenomenon was reduced with the addition of nanoparticle TiO2 catalyst compared with conventional P25 powder. Therefore, this submerged membrane photocatalysis reactor can faciliate potential application of photocatalytic oxidation process in drinking water treatment.     

常温酸性腐蚀对热障涂层性能的影响

采用酸性盐雾腐蚀试验对物理气相沉积法制备的热障涂层进行了常温腐蚀,研究了常温酸性盐雾腐蚀对热障涂层的微观形貌以及高温性能的影响.试验结果表明：常温酸性腐蚀使热障涂层表面变得粗糙不平,产生了较大的裂纹.经过150次高温循环氧化后,顶层氧化锆晶粒排列疏松,裂纹进一步扩展,中间层--粘结层氧化速度加快,生成了疏松的TGO层.TGO的体积膨胀效应使得陶瓷/粘结层界面结合力降低,缩短了涂层的使用寿命.
