短程硝化厌氧氨氧化联合处理实际垃圾渗滤液
|
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NH_4~+-N从91.5 mg/L提高到1 053 mg/L,出水NO_2~--N高达930 mg/L,NO_2~--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NO_2~--N全部由SBR的出水提供,NH_4~+-N、NO_2~--N去除率均维持在98%以上,实现了系统对氮的深度处理。
Taking the actual landfill leachate as the research object,the nitrogen removing characteristics of shortcut 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 NH_4~+-N concentration increases from 91.5 mg/L to 1 053 mg/L,The effluent NO_2~--N concentration is as high as 930 mg/L,and NO_2~--N accumulation rate reaches more than 96.7%. ASBR influent is prepared from leachate,SBR effluent and tap water in proportion. Starting from the 20 th day of the experiment,all of the NO_2~--N in ASBR influent is supplied by SBR effluent. The removing rates of both NH_4~+-N and NO_2~--N are kept at 98% or more,realizing the advanced treatment of nitrogen by the system.
