摘要
采用水力循环方法将人工驯化培养后的微生物固定于活性炭上,以达到生物强化的目的。结果表明,经生物强化后的生物活性炭对TOC及AOC的去除效果均优于普通活性炭,其中TOC的平均去除率提高9%,对AOC的去除率可提高10%～30%。采用超声波振荡技术对活性炭上附着菌的生长情况进行研究发现,水力循环法固定于活性炭上的附着菌,牢固程度与稳定运行期间活性炭上自然生长的附着菌相差不大,对氨氮去除的持久性明显高于自然生长的附着菌。
The immobilization of cultured microorganisms onto the activated carbon by using hydraulic recycling to achieve bio-enhancement effects was investigated. The results demonstrated that biological activated carbon （BAC） after bio-enhancement could accomplish higher TOC and AOC removal efficiency than plain activated carbon, as indicated by increased TOC and AOC removing efficiency by 9 % and 10%-30%, respectively. Investigations of bacterial attachments by using ultrasonication technology suggested that there was no substantial difference in attachment intensity between BAC after hydraulic recycling and BAC after natural growth. BAC after hydraulic recycling performed better than that with natural growth in persistence of removing ammonium-nitrogen.
