摘要：

In a previous paper the A.A. used a mathematical model to describe the complex mechanisms affecting heavy metals distribution between liquid and solid phases in order to predict the quality of effluents of an activated sludge biological treatment system. In the present work the mathematical model is employed to depict the behaviour of particulate and soluble zinc in large municipal wastewater treatment plants for which operating data were available in the existing literature. The results obtained by this model, compared with experimental data, describe zinc behaviour in activated sludge systems satisfactorily. The behaviour of some other metals (zinc, nickel, copper, chromium), studied in solid and liquid flows of a municipal wastewater treatment plant in the north-east of Italy (5000 m3/day), is satisfactorily simulated.
