The oil sewage disposed process is a complex disposal technique. The disposal process is more difficult for the change of PH Flux temperature of raw water and the other polluted quality. At present the disposed water by the system of oil of sewage is unstable and high cost. Now the method for the oil of sewage have physics chemistry physical chemistry and biology etc. In the every disposed method has its own specially, Basis of the oil sewage condition of power plant. The text use chemic method. Another word is method of Flocculation-deposition. Injecting Dosage into sewage. Making small suspends grain and the electrophorus colloid gather into bigger colloid and deposit. Separated it from water and purify the oil sewage. Make disposed oil water up to grade.

含油污水处理工艺是一个复杂的处理过程,在处理过程中由于受到原水浊度、PH值、配水流量、原水温度和其他水质污染等因素的影响,处理难度相当大,现时的含油污水处理系统普遍存在处理后的水质不稳定和处理成本高等问题,国内外含油污水处理采用的方法有物理法、化学法、物理化学法和生物法等,每种处理方法都有自己的特点,结合电厂含油污水的情况,本文主要采用化学法,具体来说是采用絮凝沉淀的方法,通过向废水中投加混凝剂,使细小的悬浮颗粒和带电胶体微粒聚集成较大颗粒而沉淀,使其与水分离,使含油污水得到净化,使处理后的废水各项指标达到排放标准。

Lanthanides belong to the sixth cycle of the periodic table Ⅲ B family, are all solid metal, they are La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, holmium, erbium, thulium, ytterbium, and lutetium were 15 kinds of metals and their periphery are two layers of electronic 5d16s2, while the peripheral third layer f orbital but never zero to 14, so the external electronic structure of 4f0-145d16s2, and therefore these elements in oxidation number are to 3, very close chemical properties, extraction, when it is difficult to separate them they are mostly multi-element mineral mix, more difficult to increase refining, and their atomic number of 57-71, one by one to increase the number of protons the nucleus, and thus extranuclear electron of gravity is also growing, so that atomic radius decreases with increasing atomic number Z, which makes lanthanides contraction, ionic radius is also reduced, which also makes Zr, Hf, Nb and Ta, Mo and W, the atom and ionic radius very close to each other they also determine a similar nature, resulting in difficult separation, also the tribe Ⅷ of the fifth cycle, ruthenium, rhodium, palladium, and the sixth cycle, osmium, iridium, platinum is very similar in nature, thus The six elements, said platinum group elements.

镧系元素属于周期表第六周期中ⅢB族,全部是固体金属,它们是镧、铈、镨、钕、钷、钐、铕、钆、铽、镝、钬、铒、铥、镱和镥共十五种金属元素,它们的外围两层的电子均是5d16s2,而外围第三层的f轨道电子却从零增加到14个,所以外围电子结构为4f0-145d16s2,而使这些元素氧化数均为+3,化学性质极为接近,提炼时很难分开,它们的矿石又大多是多种元素混在一起的,更增加提纯难度,它们的原子序数为57-71,核内质子数逐个增加,因而对核外电子引力也不断增强,使原子半径随原子序数Z增加而减小,这就使镧系元素收缩、离子半径也缩小,这也使得Zr和Hf,Nb和Ta、Mo和W等原子和离子半径都很接近、也决定了它们彼此性质类似,以致难以分离、也使第Ⅷ族中第五周期的钌、铑、钯和第六周期的锇、铱、铂在性质上极为相似,因而称这六个元素为铂系元素。

The results showed that the TiN andN films are polycrystalline phase. The properties and structure of TiN films are mainly determined by the N2 mass flow rate, and as the N2 mass flow rate increases, the structure of the TiN films transforms to f.c.c. type leading to better the properties of films. The presence of negative bias voltage can optimize the grain of TiN films, lower the defect proportion and denser the films, which improves the hardness of films. The TiN films conform to the free carrier absorption mechanism and there are many of free electrons with lower N content in TiN films. With the increase of N content, the quantity of free electrons and reflectivity of films decrease, and the plasma frequence shifts to the lower energy, which leads to the regular change of colors of films from silver, yellowy, golden to yellow-red, meanwhile the lightness of films decreases. The goldenN film consists of TiN and ZrN phase, but belongs to a sigle f.c.c. structure with (111) preferred orientation. The Zr-doping dosen't change the position of the valance band, conduction band and forbidden band ofN film, but leads to the presence of new energy levels, which is the reason thatN film remains golden. The transparent hard films with good corrosion resistance and high hardness have been prepared and the further reseachs showed that the grain size of those films is by far smaller than the wave length and the width of forbidden band of those films is very broad, is the reasons that those films are transparent.

研究表明:氮化钛和N 薄膜为多晶态,氮流量决定了氮化钛薄膜的结构和性能,增加氮流量能使氮化钛薄膜的结构向面心立方结构转变,从而得到性能良好的氮化钛薄膜;施加负偏压能优化氮化钛晶粒和减少薄膜中的缺陷,使膜层变得更致密,从而提高薄膜硬度;氮化钛主要遵循自由载流子光吸收,氮含量较少时薄膜中的自由电子数目较多,随着氮含量的增加,薄膜中的自由电子数目不断减少,反射率逐渐降低,等离子体频率向低能端移动,从而使薄膜颜色出现规律变化,由金属色银白色到淡黄、金黄再到红黄,并且薄膜亮度呈下降趋势;金黄色的N 薄膜中存在TiN 和ZrN 的分离相,但其为单一的面心立方结构并具有(111)面择优取向;相对于TiN 薄膜,Zr 掺杂后,并没有使薄膜的导带、价带和禁带发生变化,只是在TiN 禁带内增加了新能级,这也正是掺杂Zr 后,薄膜仍
