摘　　要：目的评价某火力发电厂脱硫改造工程的职业病危害程度，提出防护对策和建议。方法选择与该项目相似的工程进行类比调查，采用检查表法、类比法，进行定性、定量分析评价。结果类比现场，在正常生产下，重铬酸盐、一氧化碳、一氧化氮、二氧化氮、二氧化硫、三氧化硫、氯化氢、石灰石粉尘、石膏粉尘和高温均符合要求，噪声LEX,8h舢结果除1#综合楼巡检岗为87-3dB（a）超标外，其余LEX,8h值在71．2-80．5dB（A）之间。结论该项目属于职业病危害严重的建设项目。企业应按照报告书建议对职业病危害因素防护措施进行完善。[Objective] To evaluate the harmful degree of occupational hazards in the desulfurization renovation project of a thermal power plant, and put forward protection countermeasures and suggestions. [Methods] The similar project was selected for analogy investigation. The check list method and analogy method were applied for qualitative and quantitative analysis. [Results] At the scene of the analogy, dichromate, carbon monoxide and nitric oxide, nitrogen dioxide, sulfur dioxide, sulfur trioxide, hydrogen chloride,limestone dust,gypsum dust and heat were in line with the requirements, for noise LEX,8h, except for 87.3 dB （A） at inspection post of 1# comprehensive building, the rest were between 71.2-80.5 dB（A）. [Conclusion] This project belongs to the construction project with serious occupational hazards. This enterprise should improve protection measures against occupational hazards in accordance with the recommendations of the report.
