The application of artificial neural network in wastewater treatment

摘要

In this paper, the applications of artificial neural network(ANN) in wastewater treatment quality control are reviewed. The main applications include three fields: to predict the effluent quality, such as the concentration of COD, N and P; to soft sensing some parameters hard to measure on site, such as BOD; to measure some parameters more accurately, such as heavy metals. In combination with the developing trend of the researches, the future developing direction of ANN is analyzed.
