摘　　要：本文采用传热实时监测方法,以一定频率28 kHz的超声波对冷却水进行处理,考察了超声作用下水质硬度、水温变化对处理效果的影响。结果表明,超声波具有比较明显的阻垢作用,在低硬度下有较高的阻垢率,并使过程的传热系数显著提高,同时超声波能够抑制硬度水中Ca^(2+)的析出。The paper studied 28 kHz ultrasonic anti-fouling performance by cooling water treatment under the different temperature and hardness through fouling resistance dynamic monitoring method.The experimental results showed that ultrasonic water treatment has obvious antifouling effect.The ultrasonic anti-fouling device has the better anti-fouling effect and can greatly increase the heat transfer coefficients at low water hardness.The ultrasonic anti-fouling device can also reduce Ca^（2＋）separate out from hard water.
