医疗废物安全处理技术优选方法

从医疗废物的产生量、特性和处理要求出发,定性分析了各类处理技术的优缺点和适宜性,并初步筛选出4类可行技术:高温处理法、高压蒸汽灭菌法、微波灭菌法和化学消毒法,结合我国处置现状、经济水平、政策导向和国际趋势等因素,基于AHP方法建立了“4层-13指标-4方案”层次决策模型,对4项处理技术进行了定量评估,并以杭州市医疗废物安全处置项目为例进行验证,其结果显示高温处理法是此项目的最佳选择.对所建立的医疗废物安全处理技术优选方法体系进行了总结.实例研究证明,该体系可为医疗废物安全处理技术选择提供决策支持.

Optimal Selection Method of Technologies of Medical Wastes Treatment

This paper investigate the medical wastes(MW) definition,production,characteristics and technical requirements,which is decisive for properly selecting methods for medical wastes treatment(MWT).Base on this,the advantages/disadvantages and adaptation of various treatment options are qualitatively analyzed and broadly compared.Then,four kinds of technologies,namely the thermal treatment,autoclaving,chemical disinfection,and microwave disinfection,are primarily chosen.Moreover,a hierarchy decision-making model considering the disposal status,economic level,policies and international turns is further set up.According to it,4 proposed methods are effectively assessed.The result indicates that thermal treatment technology is the optimal choice for medical wastes treatment in Hangzhou city.Besides,the optimal selection method for medical wastes treatment is synthetically presented,which is suggested as a strong support for choosing optimal technology,and will contribute a lot to related research as well.
