摘　　要：随着全球工业化和城市化的加速发展,水资源的持续供应和水质的综合管理已成为重大挑战。电厂循环冷却水排水水耗巨大,出于全厂零排放的需要,不少电厂开展了循环冷却水排水脱盐等措施以提高浓缩倍率,实现循环水回用,但现有处理技术存在能耗高、系统复杂、存在二次污染等问题。为此,试验研究了电化学耦合中试试验装置在循环水处理中的应用,分析了其在除垢、防腐和废水资源化方面的效果。试验结果表明:该试验装备在去除水中硬度和碱度方面表现出显著效果,并有效降低了水体的电导率和氯离子含量,在电压为3.2 V和电流为240 A的条件下,硬度去除率最高,去除率分别为5.15%和55.77%;在电流为250A和电压为3.2V的条件下,碱度去除率最高,去除率分别为36.96%和91.41%;电化学耦合技术相较于传统加药法和常规水处理技术,有明显的经济优势。电化学耦合技术是一种高效、环保、经济的循环水处理方案,具有广阔的应用前景。With the rapid global industrialization and urbanization,ensuring continuous water supply and comprehensive water quality management has become a major challenge.Power plant cooling water consumption is significant,and to achieve zero discharge,many plants have adopted desalination measures to increase concentration ratios and enable water reuse.However,existing treatment technologies face high energy consumption,system complexity,and secondary pollution issues.To solve these problems,the application of electrochemical coupling pilot-scale equipment in cooling water treatment is experimentally studied,and the effects of electrochemical coupling pilot-scale equipment on scale removal,corrosion prevention and wastewater resource utilization are analyzed.The results show that,the equipment removes hardness and alkalinity significantly,and reduces conductivity and chloride ion content efficiently.Under conditions with voltage of 3.2 V and current of 240 A,the hardness removal rate reached the highest(5.15%and 55.77%,respectively),and under conditions with current of 250 A and voltage of 3.2 V,the alkalinity removal rate reached the highest(36.96%and 91.41%,respectively).The electrochemical coupling technology offers clear economic advantages compared with the conventional methods,providing an efficient,eco-friendly,and cost-effective solution for cooling water treatment with broad application prospects.
