| 摘 要： | 研究了人工土模拟柱对污水中氮去除的主要机制。试验结果表明，在脱氮的各种机制中，生物硝化－反硝化起着较重要的作用，对全Ｎ的相对去除率为５０％，对ＮＨ＾＋４－Ｎ的相对转化去除率为６９％；对ＳＳ的物理截留也起了一定的作用。

| Abstract: | In this paper,the main mechanisms of the waste water nitrogen rem-oval in the simulate artificial soil column was discussed,Experimental results sho-wed that biologcial nitrification-denitrification played a major role in the wastew-ater nitrogen removal mechanisms,the relatively percent total nitrogen(TN)remov-al was 50%, the relatively percent ammonnia nitrogen(NHN)removal was 69%:suspension solids(SS)mechanical retaining process played a certain role too. |
