摘　　要：采用UASB反应器,研究不同S^(2-)/NO_3^--N对硫化物、氨氮和硝态氮同步去除的影响。结果表明,S^(2-)/NO_3^--N在1/1、9/8、5/4、3/2四个阶段反应器稳定运行时,硫化物去除率为80%~100%,氨氮去除率为93%~99%,硝态氮去除率基本稳定在96%左右,脱氮除硫效果良好。在S^(2-)/NO_3^--N为9/8的最佳工艺条件下,硫化物去除率为100%,氨氮去除率达到99%,硝态氮去除率达到96%。同时探讨了S^(2-)/NO_3^--N影响硫氮同步去除的机理。The effects of different S^（2-）/NO_3^--N values on simultaneous removal of sulfide,ammonia nitrogen and nitrate nitrogen were investigated by an up-flow anaerobic sludge bed（UASB）reactor.Results showed that,under 4 stages of stable operation in the reactor with S^（2-）/NO_3^--N values of 1/1,9/8,5/4 and 3/2,the removal rate of sulfide was 80%～100%,the removal rate of ammonia nitrogen was 93%~99%,and the removal rate of nitrate nitrogen was generally remained at 96%.Under the optimal conditions with S^（2-）/NO_3^--N value of 9/8,the removal rate of sulfide was 100%,the removal rate of ammonia nitrogen was 99%,and the removal rate of nitrate nitrogen was 96%.Meanwhile,the mechanism of the simultaneous removal of sulfur and nitrogen affected by S^（2-）/NO_3^--N was discussed.
