摘要
生物处理技术因其具有高效、成本低廉、操作简便、清洁、无二次污染等特点,已被广泛应用于废气处理方面,但微生物气溶胶会作为二次污染物从废气处理设施排放到周围空气中。由于携带和传播有害微生物,微生物气溶胶对人体健康造成潜在危害和风险。废气生物处理设施既是微生物气溶胶的“汇”,也是微生物气溶胶的“源”。本文阐述了废气生物处理设施微生物气溶胶的逸散水平、群落结构和粒径分布特征,分析了其形成原因、主要来源、影响因素和暴露风险,为废气生物处理设施产生的微生物气溶胶的识别和控制技术研究提供科学依据和参考。
Biological treatment technology has been widely applied in the purification of waste gases owing to its high efficiency,low cost,simple operation,and seldom secondary pollution.However,bioaerosols can be discharged into the atmosphere as secondary pollutants from waste gas treatment facilities.Bioaerosols pose potential hazards and risks to human health due to the carrying and transmission of harmful microorganisms.Bioreactors for waste gas treatment are both sinks and sources of bioaerosols.This paper reviews the emission levels,microbial community structure,and particle size distribution characteristics of bioaerosols released from bioreactors for waste gas removal.Furthermore,we discuss the formation,sources,factors,and exposure risk of bioaerosols,aiming to provide a scientific basis and reference for the identification and control of bioaerosols,especially for those from biological treatment facilities.
