摘要
研究了人工上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NHN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。
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.
