Bioreactors for the Rapid Determination of Biodegradable Dissolved Organic Carbon (BDOC) in Drinking Water: Feed Mode Impact 快速测定饮用水中可生物降解溶解有机碳(BDOC)的生物反应器:进水模式影响
发布日期: 1997-01-01
生物反应器在20℃的稳定温度下运行,用于快速测定臭氧水中可生物降解溶解有机碳(BDOC)的含量。对连续进料和分批进料两种进料方式进行了比较和评价。从生物反应器入口和出口点之间的DOC量(BDOC)减少的角度来看,从每周充满通过1和75μm过滤器的水的储槽中供给的生物反应器在短期内(启动后7个月)的性能优于那些连续供给通过75μm过滤器过滤的水的生物反应器。 人们认为,间歇式和连续式生物反应器的性能差异可归因于间歇式生物反应器的细菌定植速度更快。此外,观察到预滤器中的生物生长在通过连续进料生物反应器系统整体去除BDOC中起着重要作用。
Bioreactors, performing at a stable temperature of 20 degrees C, were used to achieve a rapid determination of the amount of biodegradable dissolved organic carbon (BDOC) present in ozonated water. Two feed modes, continuous feed and batch feed, were compared and evaluated. Bioreactors fed from holding tanks filled weekly with water passed through 1 and 75 um filters were found to perform better in the short term (7 months after start up) than those fed continuously with water filtered on 75 um filters, in terms of the reduction in the amount of DOC between the intake and outflow points of the bioreactors, or BDOC. It is believed that the difference in performance of batch-fed and continuously-fed bioreactors can be attributed to the more rapid bacterial colonization of batch-fed bioreactors. Moreover, it was observed that biological growth in the prefilter had an important role in the overall removal of BDOC through the continuously-fed bioreactor system.
