中文摘要 针对我国目前应用的回转窑焚烧法、热解法、高温蒸汽灭菌法、化学消毒法、微波消毒法这5种医疗废物处置技术进行了分析和比较，并通过层次分析法对这5种方法进行了定量评估和筛选，在此基础上，对最优和次优备选方案排序权重进行了灵敏度分析.结果表明，回转窑焚烧法和热解法是目前我国医疗废物处置应用最广泛的技术；但层次分析法评估结果表明，高温蒸汽灭菌法用于医疗废物处置时在社会、环境、技术和经济4个因素方面综合效益与其他4种方法相比最优，化学消毒法次之；灵敏度分析表明，导致备选方案排序变化的准则层各因素变化点分别为社会因素（0.2100）、环境因素（0.3500）、技术因素（0.1200）、经济因素（0.2400），子准则层各因素对备选方案权重排序影响较小. 英文摘要 Five types of medical waste disposal technologies that are currently applied in our country were analyzed and compared such as the rotary kiln incineration method, pyrolysis method, high-temperature steam sterilization method, chemical disinfection method, and microwave disinfection method. The five methods were quantitatively evaluated and screened using an analytical hierarchy process (AHP). Based on this process, the ranking weights of optimal and suboptimal alternatives were studied using sensitivity analysis. The results show that the rotary kiln incineration and pyrolysis methods are presently the most widely used technologies for medical waste disposal in our country. The AHP shows that the comprehensive benefits of high-temperature steam sterilization in medical waste disposal are the best compared with the other four methods in terms of social, environmental, technological, and economic factors, followed by the chemical disinfection method. The sensitivity analysis shows that the change points of the guideline layer factors that lead to the change of the alternatives are the social factors (0.2100), environmental factors (0.3500), technical factors (0.1200), and economic factors (0.2400). Subcriteria factors have less influence on the weight ranking of the alternatives.
