Contact-Adsorption-Regeneration (CAR) process is a cost-effective system for wastewater treatment and has a potential for application in less-developed regions. To offer a better understanding of this process, a mathematical model was established on the basis of Activated Sludge Model No. 1 (ASM1) and by incorporating the adsorption and different hydrolysis processes. The model predictions were compared with the measured data in terms of effluent concentrations and removals of both chemical oxygen demand (COD) and NH(4)(+)-N. A good agreement between the predicted and measured data was observed, indicating that the model was capable of predicting the rapid adsorption, COD removal and nitrification processes in the CAR system. This work provides an experimental and theoretical basis for the application of the CAR process in less-developed regions.
接触吸附再生（CAR）工艺是一种具有成本效益的废水处理系统，具有在欠发达地区应用的潜力。为了更好地理解这一过程，在活性污泥模型 1（ASM1）的基础上建立了一个数学模型，并结合了吸附和不同的水解过程。根据出水浓度以及化学需氧量（COD）和 NH（4）（+）-N 的去除率，对模型预测值与实测数据进行了比较。模型预测值与实测数据吻合较好，表明该模型能够预测 CAR 系统中的快速吸附、COD 去除和硝化过程。这项工作为 CAR 工艺在欠发达地区的应用提供了实验和理论基础。
