摘　　要：针对山东某电厂的现场循环冷却水水质,采用静态阻垢试验、挂片腐蚀试验和动态模拟试验对复合阻垢缓蚀剂XD-1与XD-2在高浓缩倍数下的阻垢缓蚀性能进行了研究与评价。试验结果表明,配合加酸工艺,当循环冷却水浓缩倍数为3时,新型水质稳定剂XD-2与XD-1具有相当的阻垢缓蚀效果,而且XD-2加药量小,具有较高的经济性,可以降低火电厂水处理运行成本。According to the actual circulating cooling water quality of power plant, the performance of the XD-1 and XD-2 scale-corrosion inhibitors was studied by the method of static scale inhibition and corrosion tests with hanging sheet and dynamic simulation test. The results showed that the XD-2 scale-corrosion inhibitor had excellent performance of scale-corrosion prevention with the same effects as XD-1 when the concentration times was about 3.0 in circulating cooling water system. Furthermore, XD-2 possessed the advantages of less dosing quantity, cheaper price, and could lower the operating cost of thermal power plant.
