摘　　要：利用活性污泥数学模型ASM2D对UNITANK工艺的反硝化行为进行研究,不但可以了解影响其反硝化潜力的根本因素,还可以预测反硝化能力,预警沉淀区的反硝化。结果表明,UNITANK的三池结构不利于反硝化脱氮,B池的缺氧设置能实现部分反硝化作用;反硝化主要在沉淀区进行,但由于碳源不足,反硝化效率不高,而且存在沉淀底泥上浮的风险。The denitrification of UNITANK was studied by using activated sludge mathematical model ASM2D,through which the basic factors affecting denitrification can be understand,the denitrification ability can be predicted and the denitrification in sedimentation area can be early alarmed as well. The results showed the triple-tank structure was not good for nitrogen removal of denitrification;tank B with anoxic condition can realize partially denitrification; Denitrification carried out mainly in sedimentation area,but as carbon source was deficient,denitrification efficiency was not high and further denitrification could lead to the risk of sludge floating.
