| 中文摘要 | 使用扫描电镜(SEM)、X荧光光谱分析(XRF)、X射线衍射分析(XRD)以及X光电子能谱(XPS)对给水管网中铸铁管和镀锌钢管上的管内壁腐蚀管垢进行微观形态、化学组成、晶体结构和化合物构成等物理化学特征分析.发现管垢外部平滑而致密,内部为多孔结构.铁是管垢最重要的化学组成,管垢基本上是含铁的化合物.外层管垢可能的化学组成是-αFeOOH、γ-FeOOH、-αFe2O3、-γFe2O3、FeCl3等三价铁化合物,而内层管垢则为Fe3O4、FeCl2、FeCO3等二价铁及二价铁与三价铁共同存在的化合物.管垢的特征取决于管网水力条件、水质条件和管材本身特性.; Scanning electron microscopy,X-ray fluorescence spectroscopy,X-ray diffraction and X-ray photoelectron spectroscopy were used to analyze the microstructure,chemical composition,crystalline structure and compound constitute of the corrosion scale from cast iron pipe and galvanized steel pipe in drinking water distribution systems.The outer of the corrosion scale was compact,while the inner was porous.Iron was the primary chemical element of the corrosion scale,and the composition of the scale was iron compounds.The outer scale were ferric compounds such as α-FeOOH,γ-FeOOH,α-Fe_2O_3,γ-Fe_2O_3,FeCl_3,while the inner were ferrous compounds such as Fe_3O_4,FeCl_2,FeCO_3.The characteristics of the corrosion scale was lying on hydraulic conditions and water quality in distribution systems,and the characteristics of iron pipe materials.; 国家自然科学基金项目(50578081); 国家高技术研究发展计划(863)项目(2002AA601140) |
