概要

Abstract

This paper discusses the applicability of advanced model-based control
to enhanced wastewater treatment processes (EWWTP's). A typical EWWTP called
A2O process consisting of an anaerobic reactor, an anoxic reactor and a
oxic reactor is introduced in order to explain how nitrogen and phosphorus
are removed biochemically in the reactors. Then, the models of the A2O
process are briefly described. After introducing the fundamental idea of
model predictive control (MPC) scheme that is one of major model-based
control schemes, an example of the MPC for the A2O process illustrates
the effectiveness and the limitation of the presented MPC scheme through
numerical simulations. Based on the results, the paper discusses the problems
to be solved and/or examined in order to apply the model-based control
technologies such as the MPC to real-world A2O processes and other EWWTP's.
