| 摘 要： | 通过对亚硝化反应器中的氨氮、亚硝酸盐氮变化趋势的试验研究,认为渗滤液中存在着可以转化成氨氮的有机氮,但有机氮的转化不是在瞬时完成的。利用劳伦斯-麦卡蒂模式求得模型参数为氨氮vmax=4.67 mg/(mg.d),Ks=464.4 mg/L,Y=0.1966 mg/mg,Kd=0.55384/d,通过模型得出了反应器内生物量浓度、出流水质与污泥龄的关系,以期为实际工程中垃圾渗滤液生物脱氮提供借鉴。 |
| 关 键 词： | 晚期垃圾渗滤液 短程硝化 污泥龄 动力学模型 |

| Abstract: | Through the study on change in nitrogen of NH3-N and nitrite in nitrosation reactor,it is recognized that there was organic nitrogen in the leachate which can be transformed into ammoniacal nitrogen and the whole transformation can not occur instantaneously.The parameters obtained by dynamics study with Lawrence-Mc Carty model are as follows: vmax=4.67 mg/(mg·d),Ks=464.4mg/L,Y=0.1966 mg/mg,Kd=0.55384/d.The relations between bio-mass,effluent quality and sludge age are derived by Lawrence-Mc Carty model,which may provide reference for leachate biodenitrification of actual projects. |
