  • 摘要: 将一株碘普罗胺降解菌Pseudomonas sp.I-24及从菌株中破碎得到的降解酶分别与活性污泥同时挂膜,考察强化陶粒-曝气生物滤池(BAF)对微污染水源水中碘普罗胺(IOP)的处理效果,结果表明,降解菌和降解酶对IOP的去除率有稳定的提高,在水力负荷0.08 m3·(m2·h)-1,溶解氧9.5 mg·L-1,碳源为淀粉的条件下,2组滤池IOP最大去除率分别为98.12%和98.68%,且在不利条件下运行稳定性较强。然而投加降解菌和降解酶的滤料表面生物数量少于对照组滤料,表明降解菌和降解酶的投加存在影响生物膜种群结构的可能。
    Abstract: The iopromide(IOP) degrading strain Pseudomonas sp.I-24,isolated from the laboratory,as well as the degradation enzyme extracted from the same strain were added to ceramic biological aerated filters(BAF) with biofilm forming activated sludge.IOP removal efficiencies in micro-polluted receiving water were investigated and the results are described below.Supplementation of strain and enzyme were beneficial to the IOP removal process and the highest removal efficiency of IOP was 98.12% and 98.68% respectively with a hydraulic load of 0.08 m3·(m2·h)-1,DO 9.5 mg·L-1 and starch as the carbon source.Moreover,both operations were stable.However,there were less microbes in the ceramics containing the degrading strain and enzyme compared to the control group,suggesting that the presence of Pseudomonas sp.I-24 and the enzyme impacted the biofilm community structure.
