Description
Summary:Based on our newly developed Fully Coupled Activated Sludge Model (FCASM), a biological-hydraulic coupled model (FCASM-Hydro) for the activated sludge system was established. In FCASM, the functional organisms existing simultaneously in the activated sludge system were separated into eight groups, and the interaction relationships of them were taken fully into account. Moreover, to assess the efforts of hydraulic activity, FCASM-Hydro was established using one-dimensional (1-D) advection-dispersion equation, on the basis of FCASM. FCASM Hydro was verified by modeling full-scale biological nutrient removal at an anoxic/aerobic (A/O) wastewater treatment plant (WWTP). For numerical simulation, the model was compared with Lee-Hydro using Matlab/Simulink software, respectively. Since all parameters on the two models were identical, the advantages of the FCASM-Hydro coupled model over the other model were demonstrated in the comparative study on nutrient removal from effluent measurements.
