摘    要:通过装载改性聚乙烯填料的生物滴滤塔进行废气中的苯乙烯生物降解实验。结果表明,通过快速排泥法挂膜,该反应器可在较短周期内实现微生物的驯化。苯乙烯入口浓度和空床停留时间(EBRT)是影响反应器性能的重要因素,当EBRT分别为60、45、30和15 s以及对应的入口浓度分别为950、430、350和200 mg/m3时,可实现达标排放。循环喷淋液中的硝酸盐(亚硝酸盐)对生物滴滤池的影响十分明显,在初始阶段,亚硝酸根很快被耗尽,硝酸根则相对缓慢。当循环液中的TN从102.63 mg/L下降到24.24 mg/L时,滴滤池的去除效率由94.48%下降到43.16%,部分原因是降低NOx-的浓度减弱了反硝化作用对VOC碳源的利用。

关 键 词:生物滴滤池  苯乙烯  VOCs  去除效率  NO-x

Abstract:Biological removal of styrene waste gas in a bio-trickling filter packed with the modified PE carrier was investigated.The results showed that domestication of microorganisms in the filter was completed rapidly using the method of rapid sludge discharging.Concentration of influent styrene and empty bed residence time(EBRT) were important factors affecting the performance of the filter.The emission from the filter could achieve the national discharge standard of China when the influent concentrations were 95...
Keywords:bio-trickling filter  styrene  VOCs  removal efficiency  NO-x
