摘　　要：延长油田某联合站污水处理系统上午处于停运状态,而下午高负荷运转,导致污水处理系统间歇运行,处理难度大,效果差。通过技术改造,采用适应抗冲击力强的污水处理工艺,解决了间歇性污水处理效果差的问题,出水达到含油量≤3 mg/L、悬浮物≤2 mg/L、粒径中值≤2μm的注水水质标准,同时污水处理费用由5.6元/m^3降至5.2元/m^3。The sewage treatment system of a joint station in Yanchang oilfield was out of service in the morning,while it was under high load in the afternoon,which led to intermittent operation of the sewage treatment system.Through technical transformation,sewage treatment process with strong impact resistance was adopted to solve the problem of poor treatment effect due to intermittent influx.The effluent could meet the injection quality standard including oil content less than 3 mg/L,suspended matter content less than 2 mg/L,median particle size less than 2μm.Meanwhile,the sewage treatment cost was reduced from 5.6 yuan/m^3 to 5.2 yuan/m^3.
