ASM No.2d模型模拟SBR工艺同步脱氮除磷效能

SBR工艺由于处理上的高效性和操作上的灵活性在世界范围的污水处理领域得到广泛应用.采用国际水质协会1999年提出的ASM No.2d模型,利用matlab作为程序开发工具编制计算模型,并利用该模型对一实验室规模SBR系统进行模拟.模拟过程中动力学和化学计量参数采用ASM No.2d给出的典型参数值,并结合实际SBR系统进行了修正.结果表明,该模型能够较好模拟SBR工艺同步脱氮除磷效能,说明应用ASM No.2d进行SBR系统的模拟能够对SBR系统的优化和控制起辅助作用.

Simulation of simultaneous nitrogen and phosphorus removal in SBR system by activated sludge model No.2d

For its high efficiency and flexibility, SBR system becomes a worldwide application in the wastewater treatment. In this study, activated sludge model No.2d given by IAWQ was used for simulation of an experimental SBR system and matlab was used for model compilation and calculation. In the process of simulation, typical parameters given by the ASM No.2d were used as kinetic and stoichiometric parameters and modified with the practical SBR system. The results showed that the simultaneous nitrogen and phosphorus biochemical removal of the SBR system was simulated well by the model. The simulation model is capable of being applied to optimization, control and monitoring of SBR system.
