Abstract: The currenttreatment of circulating cooling water is limited to descaling with little scale inhibition，which israrely reported. This study proposed a new technology of electrochemical treatment of circulating cooling water by using simulating the treatment of circulating water by a high frequency electric field in electrolytic system. Optimal operational conditions were obtained by adjusting electrochemical parameters，and the mechanism of the process was analyzed. Based on the experimental data，the device was applied on a pilot scale at a facility. The results confirmed the optimal experimental conditions，with the current of 16 A，voltage of 5 V，plate spacing of 75 mm，and flow of 1000m3/h. The result suggested that this process had excellent scale inhibition convenience and efficiency.

摘要： 目前冷却循环水的处理方式主要局限在除垢方面且除垢效果有限，在阻垢方面少有报道。为了解决这一问题，本文提出了一种电化学法处理冷却循环水的新技术。采用自制电解系统对模拟循环水进行高频电场处理，通过调整电化学参数得到了最佳工艺条件，并深入分析了工艺机理。在实验研究基础上本装置在某企业进行了中试，进一步验证及完善了工艺条件。得出当电流为16 A、电压为5 V、极板间距为75 mm、流量为1000 m3/h时处理效果最佳。研究结果表明：该工艺具有极佳的阻垢效果；可使老化水垢松软便于剥离去除，表现出很好的除垢效果；可有效改变沉积物的晶型；方便高效，绿色环保。
