摘　　要：泄漏工艺物料对循环水系统运行危害巨大。通过实验室模拟现场泄漏物料条件研究了泄漏物料对循环水水质及微生物繁殖的影响,制定了包括泄漏物料检测,腐蚀、结垢和微生物控制的循环水处理方案。30个月的连续运行结果表明:碳钢监测试管的平均腐蚀速率为0.0186 mm a,黏附速率为7.85 mg(cm^(2)·月),异养菌总数为4.85×10^(4)个mL,平均生物黏泥量为1.01 mL m^(3),循环水处理效果可满足生产装置安全稳定运行的要求。The leaking process materials do great harm to the operation of circulating cooling water.The influence of leakage materials on the quality of the circulating cooling water and the reproduction of microorganisms was studied by simulating the condition of leakage material in the laboratory.The scheme of circulating cooling water treatment including leakage material detection,corrosion,scaling and microbial control was established.The results of continuous operation in a refinery for 30 months showed that the average corrosion rate for carbon steel test tube was 0.0186 mm a,the average adhesion rate was 7.85 mg(cm^(2)·month),the average total number of heterotrophic bacteria was 4.85×10^(4) mL-1,and the average quantity of the slime was 1.01 mL m^(3).The effect of circulating water treatment meets the requirements of safe and stable operation of the production plant.
