Abstract
The kinetics of simultaneous removal of carbon, nitrogen and phosphorus from a synthetic wastewater in an innovative up-flow aerobic/anoxic sludge fixed film (UAASFF) bioreactor was investigated. The kinetic analysis was performed using the experimental data obtained in an earlier study where the UAASFF bioreactor was examined under different operating conditions by changing three independent variables, HRT, COD:N:P ratio and aeration time. In the analysis, different kinetic models (Monod, first-order, second-order and Stover-Kincannon models) were evaluated. The maximum removal efficiency of COD, total nitrogen (TN) and phosphorus (TP) were obtained to be 95.42, 79 and 79.1 %, respectively. All the models examined, gave high correlation coefficients for carbon, nitrogen and phosphorus removal. Biokinetic coefficients were determined as Y= 0.417-0.496 g VSS/g COD, k = 0.027-0.053 d , µ =1.36 g VSS /g VSS.d, K =37.96 g/l.d U =38.46 g/l.d, d max B , max 1
研究了新型上流式好氧/厌氧污泥固定膜(UAASFF)生物反应器对合成废水中碳、氮、磷的同时去除动力学。使用实验数据获得的动力学分析在早期研究UAASFF生物反应器研究在不同操作条件下通过改变三个独立变量,荷尔蒙替代疗法,鳕鱼:N: P比、曝气时间。在分析中，评估了不同的动力学模型(Monod、一阶、二阶和Stover-Kincannon模型)。COD、TN和TP的最大去除率分别为95.42%、79%和79.1%。所有经过检验的模型都给出了碳、氮和磷去除的高相关系数。生物动力学系数为Y= 0.417 ~ 0.496 g VSS/g COD, k = 0.027 ~ 0.053 d，µ=1.36 g VSS/g VSS。d, K =37.96 g/l。d U =38.46 g/l。d, d马克斯B,最大值1
