Infectious waste disinfection is an essential process in medical waste management that may cause release of some pollutants. In this study, the PAHs concentration at the disinfection was investigated. The change in the release rate of PAHs in two including infectious waste reduction and increasing the segregation ratio was estimated. The results showed that the PAHs concentration was 1172 - 2066 ng/m. The specific concentration of PAHs was 852 ng/ton of infectious waste in average. The annual emission of the PAHs resulting from infectious waste disinfection is estimated to be 612.6 kg. Reduction of infectious waste caused by redefining infectious waste and increasing the segregation ratio leads to reduction of PAHs concentration by 50%. Increasing the ratio of segregation and redefinition of infectious waste that led to reduced waste loading volume are essential measures that reduce the emissions of pollutants as by-products of disinfection.
传染性废物消毒是医疗废物管理中的一个重要过程，这一过程可能会导致一些污染物的释放。在本研究中，对消毒过程中多环芳烃（PAHs）的浓度进行了调查。估算了在减少传染性废物和提高分类比例这两种情况下多环芳烃释放率的变化。结果表明，多环芳烃浓度为1172 - 2066纳克/立方米。多环芳烃的具体浓度平均为每吨传染性废物852纳克。据估计，传染性废物消毒产生的多环芳烃年排放量为612.6千克。通过重新定义传染性废物和提高分类比例来减少传染性废物，可使多环芳烃浓度降低50%。提高分类比例以及重新定义传染性废物从而减少废物装载量，是减少作为消毒副产物的污染物排放的重要措施。
