同时使用臭氧气体和UV-C辐射有效地去污染传染性废物,减少8log.的细菌负载. 这种环保方法为管理医疗废物和预防疾病传播提供了一个可持续的替代方案.
科学领域:
- 环境科学 环境科学
- 微生物学 微生物学
- 公共卫生 公共卫生
背景情况:
- 传染性医疗废物对公共健康和环境构成重大风险,COVID-19流行病等事件加剧了这种风险.
- 传统的废物管理方法,如自动封装和焚烧,具有局限性,包括潜在的环境污染和危险残留物.
- 越来越需要安全,可持续和有效的传染性废物消毒方法.
研究的目的:
- 研究臭氧气体和紫外线辐射的有效性,单独或组合,用于消毒传染性固体废物.
- 评估不同臭氧度和暴露时间对细菌无活化的影响.
- 为了比较这些方法与常见的细菌指标的有效性: *金黄色葡萄球菌*, *细菌细菌*和*假菌.
主要方法:
- 使用臭氧气体和UV-C辐射对传染性固体废物进行实验性消毒.
- 臭氧气体和UV-C辐射的单独和同时应用.
- 不同的臭氧气度 (1655000 ppm) 和暴露时间 (1180分钟).
- 使用特定指标菌株评估细菌减少.
主要成果:
- 臭氧气体和UV-C辐射的同时应用在对传染性固体废物进行净化方面表现出最高的有效性.
- 通过UV-C辐射在60分钟内实现了*金黄色葡萄球菌*的完全消除 (6-log减少).
- 仅仅臭氧气就使所有测试的细菌菌株失活,而联合处理则加速和改进了这一过程,实现了总细菌负载的8log降低.
结论:
- 同时应用臭氧气体和UV-C辐射是一种高效和环保的方法,用于传染性废物消毒.
- 这种结合的方法提供了一种可持续的替代自封和焚烧,减少疾病传播风险和环境影响.
- 优化臭氧和UV-C的使用为医疗废物管理提供了一个可扩展的解决方案,这在流行病期间和一般公共卫生保护中至关重要.

Methods of Sterilization I: Physical Methods
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics.

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
