污水处理过程生物气溶胶的同步生成及驱动方式的影响机制

污水处理过程中产生的生物气溶胶含有细菌、 真菌、 病毒等微生物，污染环境，危害污水处理厂工人及周边居民的身体健康。针对我国城市污水处理厂生物气溶胶研究现状和存在的问题，通过模型试验结合实际监测，运用现代分子生物学技术与原位分析技术，研究污水处理过程产生生物气溶胶的组分与粒径分布特征，分析微生物主要种群和化学物质的关系和相互作用，揭示生物气溶胶主要组分与污水处理单元液相组分的关联性，探究主要组分在水相→水相表层→水滴或飞沫→生物气溶胶中的传输过程与迁移变化规律，建立相关过程的动力学模式，考察驱动方式对生物气溶胶组分与粒径分布的影响，解析不同驱动方式产生的生物气溶胶的特征与规律，阐明微生物气溶胶主要组分的同步生成及驱动方式的影响机制，为城市污水处理厂微生物气溶胶的减排与控制提供科学依据。

Bioaerosols, a kind of emissions present in wastewater treatment processes contain viruses as well as different bacteria and fungi. They were considered to be correlated closely with air pollution and were proposed as a cause of potential health hazards to workers and adjacent communities. According to the research actuality and existing problems on the bioaerosols emission from municipal sewage treatment plant, modern molecular biological techniques and in situ analysis methods were applied in investigation the component characteristics and particle distributions of bioaerosols. Via modeling tests and actual monitoring, our research work will focus on analysis the interrelationships and interactions of microorganisms and chemicals, reveal the correlation between the components of bioaerosols and water in processing unit, exploration the transmission processes and patterns of the main components in bioaerosols from water phase to water surface, to drops or spray and to bioaerosols, establishment their kinetics models, investigation the rules and impacts of drive modes on the bioaerosols generation, and clarify the synchronization mechanism of main components in bioaerosols and the effect mechanism of drive mode, in order to provide the scientific basis for reduction and control the emission of bioaerosols from wastewater treatment plants.
