Correlation between Treatment Performance and Microorganism Community Structure in Inside-Circle A/O/IAT-IAT Process

  • 摘要: 对内循环式A/O/IAT-IAT同步脱氮除磷工艺在2种不同工况下的脱氮除磷效果和微生物群落结构之间的关系进行了探讨.工况1(HRT为20h,SRT为3.5 d),出水ρ(CODCr),ρ(NH4+-N),ρ(PO43-P)分别为9.2~30.6,3.2~7.6和0.2~0.5 mg/L;工况2(HRT为15 h,SRT为5.0 d),出水ρ(CODCr),ρ(NH4+-N),ρ(PO43-P)分别为1.2~23.0,0.1~2.1和0.3~1.3 mg/L.试验结果表明:与工况1相比,工况2 NH4+-N和SS平均去除率分别上升了12%和59.4%,而PO43-P却下降了7.9%.同时,2种工况下活性污泥特性也发生了变化,SV由75%~80%下降到37%~54%.2种工况下微生物优势菌没有发生明显改变,基本为变型杆菌;工况1活性污泥中优势微型动物为着生型原生动物,而工况2中则以硝化指示生物为主,且着生型后生动物的密度是工况1的10倍.
