Abstract: Considering nutrient reduction, China|s wastewater treatment plants are facing the challenge to upgrade. A modelling system has been developed to screen suitable treatment processes, while statistical methods are not feasible due to data shortage. The system comprises a database to manage different treatment unit technologies, a module to generate candidate processes, a module to simulate effluent quality with material transfer functions, and a tool to identify technologies with better performance. Application of the system showed that TP is the major restrictive control index for effluent compliance. Reverse osmosis technology is preponderant under the strictest requirement.

Keywords: wastewater treatment; unit technology combination; Monte Carlo sampling; scenario analysis; transfer function; uncertainty; discharge standard; modelling; process screening; process evaluation.
