Abstract: A kind of throat algorithm of spherical particle porous media has been established. Based on the particle size characteristics of suspended substances in the oil-bearing wastewater in oilfields,the algorithm has been used, so as to figure out appropriate particle size and mass percentage of the quartz sand particle filter,adjust the average throat of quartz sand particle filter artificially,and enhance the intercept jam effect of quartz sand particle filter on suspended substances. As a result,the removing rate of suspended substances treated by the oil field wastewater treat-ment process is increased from 62.33% to 94.50%,and the removing contribution rate of suspended substances in the secondary filtration step is increased from 10.86% to 41.20%.

摘要： 建立了一种球状颗粒多孔介质喉道算法。结合油田污水中悬浮物粒径特征，通过该算法筛选出合适的石英砂颗粒滤料粒径及占比，并人为调控石英砂颗粒滤料的平均喉道，以增强石英砂颗粒滤料对悬浮物的拦截卡堵功效，使油田污水处理工艺对悬浮物的去除率由62.33%提升到94.50%，二次过滤环节的悬浮物去除贡献率由10.86%提升至41.20%。
