摘　　要：以生物反应器填埋场原位脱氮原理为出发点,从操作参数以及处理方式2个方面进行分析,提出通过提高氧气含量、减少H2S气体、采用先低再高的回灌频率以及适宜温度、pH等操作参数的优化,为填埋场脱氮过程提供适宜环境条件;在处理方式上改变填埋场填埋结构,发展好氧、准好氧和混合型生物反应器填埋场,或联合多种异位硝化处理方法,利用填埋垃圾自身较强的反硝化能力,有效实现原位硝化反硝化和异位硝化原位反硝化作用,实现填埋场高效脱氮。Depending on the theory of in-situ denitrogenation in bioreactor landfill,the operation parameters and treatment methods were analyzed.Some suggestions were put forward,first point,optimizing operation parameters to provide the appropriate environmental conditions for denitrogenation process in waste landfill,such as more oxygen concentration,less H2S gas,low recirculation frequency at first then high,proper temperature,pH,and so on,second point,changing landfill structure to utilize self-denitrification ability of landfill waste for effectively achieving the functions of in-situ nitrification ＆ denitrification and ex-situ nitrification ＆ in-situ denitrification,and realizing high effective denitrogenation,such as developing aerobic,semi-aerobic and hybrid bioreactor landfill,and combining various kinds of ex-situ nitrification treatment methods.
