悬浮填料-曝气生物滤池氨氮去除动力学研究

Kinetic Study on Ammonia Nitrogen Removal in a Suspended Medium-Zeolite Biological Aerated Filter

悬浮填料-曝气生物滤池为双层反应器,下层为悬浮填料,上层为沸石曝气生物滤池,试验中分别研究了上下层对温度的动力学响应机制。试验以零级反应和一级反应分别对下层悬浮填料和上层沸石填料进行动力学模拟,模拟效果较好,分别求出上下层动力学方程:v=2.78×1.13^(T-19.3)、ln C_e/C_0=0.79×1.10^(T-9.3)×h,回归系数分别为0.97,0.88。

Suspended filler-aeration biological filter is a double-layer reactor, the lower layer is suspended packing and the upper layer is a zeolite aeration biological filter. In the experiments, dynamic response mechanisms of the upper layer and the lower layer to the temperature were studied respectively. The dynamic simulations of the lower suspension packing and the upper zeolite packing were carried out based on the zero-order reaction and the first order reaction respectively. The simulation results were good, and the upper and lower dynamic equations were obtained respectively： v=2.78 × 1.13（T-19.3）,ln C_e/C_0=0.79 × 1.10（T-9.3）× h, the regression coefficients were 0.97 and 0.88,respectively.
