电化学处理系统在电厂循环冷却水上的试验研究
Experimental Study of Electrochemical Treatment System on Circulating Cooling Water in Power Plant
摘要: 本文研究了电化学处理系统在电厂循环冷却水中的应用效果。通过对比试验发现，电化学装置运行能够有效降低循环水的硬度和化学需氧量(COD)，具有良好的杀菌灭藻效果，适度降低氯离子含量，并提升循环水的浓缩倍率，从而显著节约水资源。研究还表明，电化学处理装置能够降低循环水的总碱度并提高溶液体系的电导率，在保证水质符合要求的情况下进一步提高浓缩倍率，达到了节水的目的。电极在稳定运行12小时后效率开始下降。此外，电化学处理装置的使用减少了循环水系统中杀菌剂、阻垢剂和缓蚀剂的用量，有效降低了系统运行的药剂成本。
Abstract: This study investigated the application effects of electrochemical treatment systems in the recirculating cooling water of power plants. Comparative experiments revealed that the operation of electrochemical devices can effectively reduce the hardness and chemical oxygen demand (COD) of the circulating water, exhibit good bactericidal and algicidal effects, moderately decrease chloride ion content, and increase the concentration ratio of the circulating water, thereby significantly conserving water resources. The research also showed that electrochemical treatment devices can lower the total alkalinity of the circulating water and enhance the conductivity of the solution system, further increasing the concentration ratio while ensuring that the water quality meets requirements, thereby achieving the purpose of water conservation. The efficiency of the electrodes begins to decline after stable operation for 12 hours. Additionally, the use of electrochemical treatment devices reduces the dosage of bactericides, scale inhibitors, and corrosion inhibitors in the circulating water system, effectively lowering the reagent costs of system operation.
