A biofilm model is presented for process engineering purposes--wastewater treatment plant design, upgrade and optimisation. The model belongs in the 1D dynamic layered biofilm model category, with modifications that allow it to be used with one parameter set for a large range of process situations. The biofilm model is integrated with a general activated sludge/anaerobic digestion model combined with a chemical equilibrium, precipitation and pH module. This allows the model to simulate the complex interactions that occur in the aerobic, anoxic and anaerobic layers of the biofilm. The model has been tested and is shown to match a variety of design guidelines, as well as experimental results from batch testing and full-scale plant operation. Both moving bed bioreactors (MBBR) and integrated fixed film activated sludge (IFAS) systems were simulated using the same model and parameter set. A new steady-state solver generates fast solutions and allows interactive design work with the complex model.
提出了一种用于工艺工程目的的生物膜模型——污水处理厂的设计、升级和优化。该模型属于一维动态分层生物膜模型类别，并经过修改，使其能够使用一组参数适用于大范围的工艺情况。该生物膜模型与一个通用的活性污泥/厌氧消化模型以及一个化学平衡、沉淀和pH模块相结合。这使得该模型能够模拟生物膜好氧、缺氧和厌氧层中发生的复杂相互作用。该模型已经过测试，结果表明它符合各种设计准则以及分批测试和全尺寸工厂运行的实验结果。使用相同的模型和参数集对移动床生物反应器（MBBR）和集成固定膜活性污泥（IFAS）系统进行了模拟。一种新的稳态求解器能够快速生成解决方案，并允许对复杂模型进行交互式设计工作。
