中文摘要 | 本文探討逆流式氣泡管反應器(bubble column reactor, BCR)系統參數對臭氧化效能之影響。所考慮的臭氧化效能包括:臭氣利用率、污染物去除率及臭氣尾氣排放之濃度等。針對氣泡管反應器,本研究加入前人所忽略之因子,例如:臭氧自解及臭氣與污染物反應對臭氧質量傳輸之影響(即增進因子)、壓力變化、氣體上升速度變化及延散( dispersion)等。所建立之精細單段氣泡管反應器模式將可提供未來更進一步探討多段氣泡塔反應器之用。研究成果可提供用於氣泡管臭氧反應器放大設計及經由臭氧化去除污染物之有用資料。簡化本模式於無臭氧化污染物反應時,分析結果與Huang et al.(1998 )相同。 |
英文摘要 | This paper analyzes the countercurrent single-stage bubble column reactor (OCR) for gas-liquid ozonation systems. The effects of system variables on ozonation performance are examined. The aspects of ozonation performance considered include the efficiency of ozone utilization, the efficiency of pollutant removal, and the emission concentration of ozone gas. This analysis takes into account the effects of ozone decomposition and the ozonation of pollutants on the ozone mass transfer (i.e. , enhancement factror, Er), the variation of pressure (P) and of gas velocity (UG) along the column. And dispersion effects (PeG. PeL). The obtained detailed single-stage OCR model may be used in further development of multi-stage OCR model in the future. The results of this study can provide useful information for rational design of a BCR ozonation contactor, and are important with respect to the treatment of pollutants via ozonation. For the simplified case without ozonation of pollutants, this analysis reduces to that of Huang et al. (1998). |
