摘  要厌氧氨氧化和自养脱硫反硝化耦合工艺（AADD）是一种有前景的创新技术，用于生物氮和硫的去除。在本研究中，启动已接种有成熟的anammox颗粒污泥和产甲烷颗粒污泥的上流式厌氧污泥床反应器并运行245天，以此评估该反应器对废水中氮和硫的的处理情况。结果表明该反应器在脱氮除硫方面表现出了良好的性能，并显示NH4+-N，NO2--N和S2--S的去除效果非常高效，分别达到了252、333和330mg L-1。氮和硫的最高除去速率分别达到了4。00kg m-3 d-1和2。39kg S m-3 d-1，这也是耦合系统的最高报道值。当进水的NO2--N:S2—S与NH4+-N:S2--S比率设定为2。20-2。27与1。74是比较适合维护系统的稳定性。在操作过程中对厌氧氨氧化菌和自养反硝化-脱氮硫杆菌（SAA和SADD）具体活性进行了调查。SAA和SADD被认为是脱氮除硫高效率的关键因素。88797

Anammox and autotrophic desulfurization-denitrification (AADD) process is a promising technology innovations, For the removal of biological nitrogen and sulfur。 In the present study,Initiate an upflow anaerobic sludge bed reactor that has been inoculated with mature anammox granular sludge and methanogenic granulated sludge and operated for 245 days,This was used to assess the treatment of nitrogen and sulfur in the wastewater。The results show that the reactor exhibits good performance in terms of nitrogen and sulfide removal,and the removal efficiencies of NH4+-N,NO2--N and S2--S were very efficient, reaching 252, 333 and 330 mg L - 1, respectively。The maximum removal rates of nitrogen and sulfur reached 4。00kgm-3d-1 and 2。39kgSm-3d-1, respectively。This is also the highest reported value of the coupling system。 When the influent NO2-- N:S2-- S and NH4+-N:S2-- S ratio is set to 2。20-2。27 and 1。74 is more suitable for maintaining the stability of the system, In the course of the operation,the anammox and autotrophic desulfurization–denitrification (SAA and SADD) specific activity was investigated。 The SAA and SADD are considered to be a key factor in the high efficiency of nitrogen and sulfide removal。源Q于D优G尔X论V文Y网wwW.yOueRw.com 原文+QQ75201`8766
