| 摘 要： | 利用SBR(序批式反应器)研究了不同ρ(Na Cl)、曝气时间、ρ(CODCr)、进水ρ(NH4+-N)对AGS(好氧颗粒污泥)短程硝化反硝化的影响.结果表明,在p H、温度和ρ(DO)为8.0、30℃和3 mgL条件下,以及ρ(Na Cl)、曝气时间、ρ(CODCr)和ρ(NH4+-N)为20 gL、8 h、600 mgL和70 mgL时,ηA(NH4+-N去除率)和NAR(NO2--N积累率)达到最佳.当进水ρ(Na Cl)为10 gL时,NOB(亚硝酸盐氧化菌)被完全抑制,AOB(氨氧化菌)能够保持正常活性.ρ(CODCr)较高时能够促进NAR的提高.经过116 d的培养,AGS短程硝化反硝化的耐盐极限为50 gL,此时ηA小于50%,AOB被严重抑制,AGS丧失硝化能力.AGS的同步硝化反硝化作用明显,SND(同步硝化反硝化率)平均值为24.2%,SNDV(同步硝化反硝化比速率)平均值为0.63 h-1,低ρ(DO)比高ρ(DO)下的SND同步硝化反硝化作用更为明显.
