摘要： 以实际垃圾渗滤液为研究对象，研究了短程硝化SBR+厌氧氨氧化ASBR组合工艺的脱氮特性。SBR采用逐步增加进水中渗滤液比例的方式进行培养，常温条件下，进水NH₄⁺-N从91.5 mg/L提高到1 053 mg/L，出水NO₂^--N高达930 mg/L，NO₂^--N积累率达到了96.7%以上。ASBR进水由渗滤液、SBR出水和自来水按比例配制，从试验的第20天开始，ASBR进水中的NO₂^--N全部由SBR的出水提供，NH₄⁺-N、NO₂^--N去除率均维持在98%以上，实现了系统对氮的深度处理。

Abstract: Taking the actual landfill leachate as the research object,the nitrogen removing characteristics of short-cut nitrification SBR+anaerobic ammonia oxidation ASBR combined process have been studied. SBR is inoculated by way of gradually increasing the proportion of leachate in water. At room temperature,the influent NH₄⁺-N concen-tration increases from 91.5 mg/L to 1 053 mg/L,The effluent NO₂^--N concentration is as high as 930 mg/L,and NO₂^--N accumulation rate reaches more than 96.7%. ASBR influent is prepared from leachate,SBR effluent and tap water in proportion. Starting from the 20th day of the experiment,all of the NO₂^--N in ASBR influent is supplied by SBR effluent. The removing rates of both NH₄⁺ -N and NO₂^--N are kept at 98% or more,realizing the advanced treatment of nitrogen by the system.

Key words: short-cut nitrification, anaerobic ammonium oxidation, landfill leachate, combined process
