基于BioWin3.1软件对Orbal氧化沟中4种组分的模拟研究

摘要

In order to simulate the organics removal and denitrification and phosphorus removal effect of the Orbal oxidation ditch process,the Orbal oxidation ditch process is numerically simu-lated based on the ASDM mathematical model and the BioWin simulation software.The compari-sons between the analog values of the model and the experimental measured values show that the simulated COD,TN,TP and ammonia nitrogen are approximately in agreement with the experi-mental ones.Studies have shown that the BioWin software can precisely simulate the organics re-moval and denitrification and phosphorus removal effect of the Orbal oxidation ditch process, which can be used at the same time for forecast of water quality in the Orbal oxidation ditch and provide the reference basis for operation and Debugging.%为了模拟 Orbal 氧化沟工艺有机物去除与脱氮除磷效果，基于 ASDM 数学模型，以 Bio-Win3.1软件为模拟平台，对 Orbal氧化沟工艺进行模拟研究。通过模型模拟值与实验实测值的对比可知，COD、TN、TP与氨氮的模拟值与实测值误差较小。说明BioWin3.1软件可以较好地模拟Orbal氧化沟工艺的有机物去除与脱氮除磷效果，可用于对 Orbal氧化沟中的水质进行预测，也可为工艺的运行调试提供参考依据。
