摘　　要：新疆百口泉联合站稀油污水系统存在回收水水质差、水中Fe^(2+)浓度高、出水不稳定、过滤器运行效果差等问题。针对污水系统存在的问题,将回收水进行预处理后再回掺至系统进水,对系统进水增加预氧化处理,同时将电解盐杀菌投加位置由过滤器后端调整至过滤器前端。工艺优化后现场应用结果表明,回收水经预处理后悬浮物、含油量控制在150 mg/L以下,系统进水水质稳定;系统进水经投加20 mg/L氧化剂处理,污水Fe^(2+)平均值由22 mg/L降至5 mg/L;电解盐杀菌投加位置调整后,解决了过滤器滤料板结和堵塞问题,同时消除了铁离子对过滤器出水水质的影响。系统优化后整体运行更平稳,注水水质可持续达标。There are some problems in the light oil-containing wastewater treatment system of Baikouquan united station,such as poor quality of recycled water,high concentration of Fe^(2+),unstable effluent,and poor operation efficiency of the filter.To tackle these problems,the recycled water is pretreated and then mixed into the system influent,which is also pre-oxidized.Additionally,the injection point of the electrolytic salt sterilization was moved from the outlet to the inlet of the filter.After process optimization,results indicate that the suspended solids and oil content of the recycled water could be controlled below 150 mg/L after pretreatment and system influent quality is stable.After adding 20 mg/L of oxidant to the system influent,the average value of Fe^(2+)could be reduced from 22 mg/L to 5 mg/L.The injection point relocation of the electrolytic salt sterilization solves the issues of filtering material hardening and plugging,and also eliminates the effect of Fe^(2+)on the quality of water from the outlet of filter.Due to system optimization,the overall wastewater treatment remains more stable and the water quality can meet the injection water standard continuously.
