| 摘 要： | 利用活性污泥2D模型对城市污水厂脱氮除磷工艺进行优化设计，构建A2/O工艺的仿真模型，通过模型校正对工艺参数进行优化，并将优化设计与传统设计法和试算法进行比较。结果表明，优化模型得出的模拟结果与实验测定值基本相吻合。优化设计法得出的污水厂基建费用和运行成本与其他两种方法相比，都有了很大的降低，虽然出水水质略有下降，但仍满足国家排放一级B标准。活性污泥2D模型可以对污水厂进行优化设计和控制。在满足出水水质前提下，降低污水厂的费用，并对以后的工艺设计提供理论指导。

| Abstract: | An activated sludge 2D model was used for optimizing the process design of nitrogen and phosphorus removal in urban sewage plant.Simulation model of A2/O process was constituted, and the model was calibrated to optimize the operation parameters.Such optimization design was compared with the traditional activated sludge process design and trial calculation method.The simulated results acquired are basically approximate to experimental values.Compared with the other two methods, the optimization design presented here has a big reduction in the sewage plant capital construction expense and running cost.Although the effluent quality has a slight drop, it still satisfies the national standard for first-level B draining.Hence, the activated sludge 2D model is capable to the optimization design and the control for sewage plants. Under the premise of meeting the requirements of effluent standards, the expenses of plants can be reduced. It also provides a theoretical guide for future process design. |
