在地下土壤渗滤系统运行的过程中，污水中的总氮主要是通过硝化作用及反硝化作用去除的。但是由于反应条件的限制，该系统出水中总氮的浓度总是不能使人满意。分析目前常用的三种提高总氮去除效率的地下土壤渗滤系统得出：间歇进水，并且在一定土壤层深度为微生物的活动提供有机物可以显著降低出水中总氮的浓度。

In the operation of subsurface wastewater in? hration system, total nitrogen in sewage was mainly removed by nitri- fication and denitrification effects. However, the total nitrogen concentration in the effluent was not satisfactory because of limited reaction conditions. This paper analyzed the three typical subsurface wastewater in? ltration systems to improve the total nitrogen removal efficiency, and research results show that the most effective method for reducing the total nitrogen concentration in effluent was intermittent water and providing organic matter for microbial in certain depth of soil layer.
