摘　　要：双氧水碱性钝化工艺已被列入国家有关行业标准,但实际清洗效果不甚理想。针对通常应用中出现的缺点,对常规的双氧水碱性钝化工艺进行了改进修改,并细化了常规的双氧水碱性钝化工艺控制参数。该技术已成功应用在华北地区某电厂,目视检查效果完全达到了亚硝酸钠钝化的水平。Alkaline peroxide passivation technology was placed into related national standards for industries. But the actual cleaning result is not satisfactory. The conventional alkaline peroxide passivation technology is improved based on the defects found in practical application. The control parameters for conventional technology were modified and elaborated. The application in a power plant in North China is successful. The visual check result reached the same level as using sulphate.
