集成式组合反应器对城市污水厂恶臭气体与微生物气溶胶的协同净化效能OA
Synergistic Purification of odors and bioaerosols by integrated combined reactor in municipal wastewater plants
通过构建中试规模的集成式组合反应器,研究了其处理城市污水厂产生的含恶臭物质和微生物气溶胶气体的性能.结果表明,该反应器在稳定运行期间对气体中的恶臭物质和微生物气溶胶均有较好的去除效果,其中硫化氢和氨的平均去除率分别为 99.76%和 99.84%,异养细菌和真菌的平均去除率分别为 93.64%和 96.24%.集成式组合反应器不同模块内的优势微生物不同,悬浮吸收模块、固定硫氧化模块和固定氨氧化模块内分别以异养细菌、嗜酸硫细菌以及氨氧化细菌和亚硝酸氧化细菌占优势.反应器出气中异养细菌和真菌气溶胶粒子的粒径主要为大于 7.0和 4.7～7.0 μm.该研究结果可为集成式组合反应器对恶臭物质和微生物气溶胶气体的同步去除提供理论参考.
A pilot-scale integrated combined reactor was constructed,and its performance in treating odors and bioaerosols produced by municipal wastewater plants was studied.The results showed that the reactor had good removal efficiencies on odors and bioaerosols.The average removal efficiencies of hydrogen sulfide and ammonia were 99.76%and 99.84%,respectively,and the average removal efficiencies of heterotrophic bacteria and fungi were 93.64%and 96.24%,respectively.The dominant microorganisms in the different modules of the integrated combined reactor were different.The suspension absorption module,the fixed ammonia oxidation module and the fixed sulfur oxidation module were dominated by heterotrophic bacteria,acid sulfur bacteria,ammonia oxidizing bacteria and nitrite oxidizing bacteria,respectively.The diameters of heterotrophic bacteria and fungal aerosol particles in the outgas were mainly greater than 7.0 and 4.7～7.0 μm.The research results of the thesis can provide a theoretical reference for the simultaneous removal of odors and bioaerosols by the integrated combined reactor.
