摘要

Abstract

The effluent total phosphorus (ETP) is an important parameter to evaluate the performance of wastewater treatment process (WWTP). In this study

a novel method

using a data-derived soft-sensor method

is proposed to obtain the reliable values of ETP online. First

a partial least square (PLS) method is introduced to select the related secondary variables of ETP based on the experimental data. Second

a radial basis function neural network (RBFNN) is developed to identify the relationship between the related secondary variables and ETP. This RBFNN easily optimizes the model parameters to improve the generalization ability of the soft-sensor. Finally

a monitoring system

based on the above PLS and RBFNN

named PLS-RBFNN-based soft-sensor system

is developed and tested in a real WWTP. Experimental results show that the proposed monitoring system can obtain the values of ETP online and own better predicting performance than some existing methods.
