| 摘 要： | 为解决石英砂过滤器处理聚驱污水过程中出现的滤料板结、反冲洗憋压、滤料流失问题,通过对石英砂过滤器进行了改造,利用搅拌装置破碎滤饼层,经现场测试,搅拌式石英砂过滤器反冲洗压力由原来的0.27~0.46Mpa降低到0.12~0.16 Mpa,滤料流失得以解决。在来水含油和悬浮固体平均41 mg/L和21 mg/L,总滤后水质含油达到5.8 mg/L以下,出水悬浮固体3.2 mg/L。油和悬浮固体去除率分别提高85%和86%。

| Abstract: | In this paper,quartz sand filter was innovated for solution of such problems as filter media hardening,backwashing pressure and filter media loss during polymer-flooding wastewater treatment by utilization of such kind of filter.Agitation device was used to break the cake layer into pieces.After on-site testing,the backwashing pressure of the agitated quartz sand filter was reduced from 0.27～0.46 Mpa originally to 0.12～0.16 Mpa and therefore filter media loss was controlled.The contents of oil and SS in the influent were averagely 41 mg/L and 21 mg/L respectively.After filtration,the content of oil got below 5.8mg/L and that of SS in the effluent was 3.2mg/L.The removal efficiency of oil and SS were increased by 85％ and 86％ accordingly. |
