采用电镜观察和荧光原位杂交技术(FISH),对亚硝化/电化学生物反硝化全自养脱氮(CANNED)工艺在不同游离氨(FA)质量浓度下反应器内细菌形态和种群结构进行了研究. 结果表明:在亚硝化段,ρ(FA)为0.5 mg/L时,氨氧化菌(AOB)和亚硝酸盐氧化菌(NOB)分别占总菌数的0.9%和2.8%;ρ(FA)为12.4～48.6 mg/L时,AOB和NOB分别占33.6%～47.4%和1.0%～2.9%,能够实现短程硝化. 在电化学生物反硝化段,当ρ(FA)为0.5～12.4 mg/L时,脱氮硫杆菌、厌氧氨氧化菌和真细菌分别占总菌数的7.2%～15.3%,7.2%～10.3%和9.1%～14.3%;当ρ(FA)增加到48.6 mg/L时,上述3种细菌所占比例分别增加到总菌数的34.5%,44.2%和60.8%,表明随着...

Scanning electron microscope （SEM） and fluorescence in situ hybridization （FISH） were used to study the bacterial morphology and community of the complete autotrophic nitrite-nitrification and electrochemical bio-denitrification combined process （ CANNED）, which was operated for ammonium wastewater treatment at different influent concentrations of free ammonia （FA）. When the mass concentration of FA was O. 5 mg/L in the nitrite-nitrification part, the AOB and NOB were O. 9% and 2.8% of the bacteria, respectively. It could achieve short-...
