It was founded that the winding turbulence promoter could effectively increase the membrane permeate flux and reduce membrane fouling. The mechanism of intensifying the filtration process was elucidated. On the other hand, the influences of backflushing on flux were examined and the operational conditions were optimized. To investigate the mechanism of membrane fouling and cleaning method, oilfield produced water, a complex system, was selected as a research object. Contaminant on membrane surface and cross section were analyzed by the scanning electron microscopy and EDX.
在膜污染和清洗方法研究中,针对油田采出水这一复杂体系,采用扫描电子显微镜和能谱分析研究膜表面和断面污染物的形态和成分;采用电渗法和电泳法测定膜材料和废水之间的电位变化关系,认为硫和硅等在膜面发生特征吸附,导致膜污染加重,并随着污染物的累积,导致渗透通量持续下降;采用膜面预处理减弱特征吸附,可有效抑制膜污染的形成;采用酸、表面活性剂、碱并配以合适的脉冲清洗,有效恢复膜的渗透通量。

The combination of shadow moiré method and Fourier transform was adoptedin the experiment, then the measurements of complex object or shape break wereachieved and also can get bigger extension, higher precision, harder influence ofenvironment, more possible of dynamic measurement. As to error of unwrapped phaseimage, a new method of error revising was described, the processing of sound was notin the course of unwrapping, but after unwrapping, the error was corrected by amending gray-image using the adjacent areas, the experiment operations were convenient and thedata operations were not needed. The results of three objects proved the method wasapplicable.
这种实验方法采用了数字影栅云纹技术与傅里叶变换基本原理的结合,实现了对于复杂面形和面形突变物体的测量,测量范围较大,精度较高,不易受到环境影响,可推广到动态测量;并针对该方法得出的解包裹后的相位灰度分布图像中出现噪声的情况,提出一种新的相位误差处理方法,即在解包裹时不用处理噪声点,而是在解完包裹后对物体相位灰度图进行灰度拟合,将噪声区域用邻近的非噪声点的灰度进行拟合,这样不仅有效地消除噪声点的误差或错误,而且操作方便、灵活,不需要进行计算。
