摘　　要：文章分析了炼油厂再生水的水质特点,通过筛选评价得到了一种可控制再生水回用于循环冷却水的缓蚀阻垢和杀菌方案,在浓缩倍数为4.0时,系统平均腐蚀率为0.052 mm/a,循环水异养菌总数1×104个/mL,生物粘泥量1.9 mL/m3,污垢热阻值2.06×10-4 m2·k/W,均低于国家标准。This paper analyzed the water quality characteristics of refinery reclaimed water and obtained a scale ＆ corrosion inhibition and bacteria inhibition project for reclaimed water reuse as industrial circulating water. When the concentrating time reached 4.0, the water treatment technology can control the average corrosion rate less than 0.052mm/a, the heterotrophic bacteria total number less than 1 × 10^4 PCS/mL, slime content less than 1.9 mL/m^3, fouling resistance lower than 2.06×10^-4 m^2-k/W, were all below the national standard..
