基于模型的MBR工艺模拟及优化

摘要

A model was established for a MBR process in an urban wastewater treatment plant,using a commercial simulation software for activated sludge processes.The model parameters were calibrated.Then the calibrated model was applied to assess the operational status of the treatment plant,andto propose a set of suitable optimization schemes.The described methods and procedures are universal,so they can provide a reference for other similar sewage treatment plants in simulation and process optimization.%利用活性污泥工艺商业软件,构建了某城市污水处理厂的MBR水处理工艺模型,对模型参数进行了率定.而后基于构建的模型,对该城市污水处理厂的运行现状进行了深入的剖析,并推荐出一套适宜的优化改造工艺.与实际改造后的运行效果对比,模型模拟结果与现场实测数据实现了良好的吻合.阐述的方法及流程具有通用性,可以为其他类似污水处理厂的工艺模拟及优化提供参考.
