两相颗粒污泥UASB结合离子交换工艺及模型化研究

运用两相颗粒污泥ＵＡＳＢ反应器结合离子交换（ＴＰ－ＵＡＳＢ－ＡＥ）新工艺处理配制葡萄糖废水取得了容积有机负荷达６２ｇ／（Ｌ·ｄ），ＣＯＤ去除率为９１．５％的高效能和过程高稳定性。对ＴＰ－ＵＡＳＢ－ＡＥ工艺的各个单元均建立了反应器级的控制数学模型，并实现了整体工艺的系统模型化控制，其系统模型化计算结果与实验结果的平均相对误差为２．２％。运用系统控制模型可对工艺过程进行精确和方便的调节，也是工程放大设计和自动化控制的基础。

Study on the Process and Modelling of Twophase Granular Sludge UASB Reactor coupled with Anionic Exchange Units

he study on a novel process of Two Phase Granular Sludge UASB Reactor Coupled with Anionic Exchange Units (TP-UASB-AE) using glucose as a substrate showed that a very highvolume loading rate LCOD, 62 g/(L. d)] wasreached when COD removal efficiency was91. 5 %. A control mathematic model for each ofTP-UASB-AE units was established separately.The whole TP-UASB-AE system was modelledthrough the combination of anionic exchangecolume models and UASB models. The mean relative error between the system mdoel calculatingresults and experimental results was 2. 2%. Thewhole process can be exactly and convenientlycontrolled by using the system control model.Italso provides a foundation for engineering scale-upand automatic control.
