摘要(Abstract)：

研究了不同质量浓度(1 mg/L和20 mg/L)多壁碳纳米管(Multiwalled Carbon Nanotubes,MWCNTs)短期(21 d)作用对序批式活性污泥反应器(SBR)废水脱氮除磷效果的影响。结果表明,1 mg/L和20 mg/L MWCNTs废水的持续作用对反应器出水NH+4-N、NO-3-N、NO-2-N和TP质量浓度(分别为0.35 mg/L、4.5 mg/L、0.1 mg/L和0.15 mg/L)及1个反应周期内的氮磷转化过程并未产生明显的影响。活性污泥3 h呼吸抑制试验表明,低质量浓度(ρ<100 mg/L)MWCNTs短暂作用(3 h)对活性污泥活性并没有明显的抑制作用。但当MWCNTs质量浓度达到g/L级别后,MWCNTs对活性污泥活性存在明显的抑制作用,而且MWCNTs对活性污泥的呼吸抑制作用与质量浓度呈正相关性。研究表明,1 mg/L和20 mg/L MWCNTs对活性污泥系统短期作用并不影响活性污泥系统脱氮除磷的效果。
