【摘要】 在采用电化学方法处理含聚合物的污水时，借助形态原位识别技术对处理聚合物污水的动态过程中气泡及油珠变化进行分析，结合絮体分形理论观察油珠与气泡的特点，并利用分形维数判断处理时间对两者的影响，观察气泡和油珠变化对除油效果的影响。结果表明：气泡分时形态变化小，分形维数保持在2.06左右；油珠分时形态变化较显著，且随着时间的增长油珠粒径变大，分形维数在1.80～1.97范围内，两者形态和分形维数具有较好的相关性。电化学处理期间，油珠和气泡会黏附在一起，并伴随着时间的延长，油珠会在气泡影响下逐渐聚集，这会提升油珠上浮分离速度，油珠平均当量圆直径会变大。在保持较高的输出电流、较短的动态停留时间或者较低的输出电流、较长的停留时间时能够促进除污。更多还原

【Abstract】 When the wastewater containing polymer was treated by electrochemical method, the change of bubbles and oil droplets in the dynamic process of polymer wastewater treatment was analyzed by means of morphological in-situ identification technology, and the characteristics of oil droplets and bubbles were observed by combining with floc fractal theory, and the influence of treatment time on them was judged by fractal dimension, and the influence of bubbles and oil droplets on oil removal effect was observed. The results showed that the time-sharing morphological changes of bubbles were small, and the fractal dimension remained at about 2.06. The shape of the oil bead changed significantly in time-sharing, and the particle size of the oil bead increased with time, and the fractal dimension ranged from 1.80 to 1.97, and there was a good correlation between the shape and fractal dimension of the oil bead. During electrochemical treatment, oil beads and air bubbles stuck together, and with the extension of time, oil beads will gradually gathered under the influence of air bubbles, which increased the floating separation speed of oil beads, and the average equivalent circle diameter of oil beads became larger when air bubbles appeared. Keeping high output current, short dynamic residence time or low output current and long residence time could promote decontamination.更多还原
