摘要：

试验探讨了复合式厌氧折流板反应器（HABR）里硫酸盐型厌氧氨氧化启动特性及不同COD对系统的影响。通过提升进水基质浓度成功启动硫酸盐型厌氧氨氧化。结果表明，硫酸盐型厌氧氨氧化是分步进行的，一号、三号和四号隔室所进行的主要反应各不相同。NH₄⁺-N、SO₄^2-、COD去除效果稳定，最高值分别为52.2%、53.7%、60.9%。较低的COD（60~150 mg/L）能促进硫酸盐型厌氧氨氧化的进行，COD过高会抑制厌氧氨氧化菌活性。

Abstract:

The influences of the start-up characteristics of sulfate-dependent anaerobic ammonium oxidation in hybrid anaerobic baffle reactor(HABR) and different COD on the system have been tested and discussed. The sulfate-dependent anaerobic ammonium oxidation has successfully been started up by upgrading the concentration of influent substrates. The results show that sulfate-dependent anaerobic ammonium oxidation proceeds step by step. The main reactions proceeding in Compartment No. l,3 and 4 are different. The removing rates of NH₄⁺-N,SO₄^2-,and COD keep stable and the maximum values are 52.2%,53.7%,60.9%,respectively. Lower COD(60-150 mg/L) can promote the proceeding of the sulfate-dependent anaerobic ammonium oxidation. However,if its COD is too high,the activity of anaerobic ammonium oxidation bacteria can be inhibited.

Key words: sulfate-dependent anaerobic ammonium oxidation, hybrid anaerobic baffle reactor, particle sludge
