The structure and principle of Back-Propagation (BP) neural network were introduced. The method and steps for building the BP neural network by the Graph User Interface (GUI) of MATLAB were also discussed. The BP neural network prediction model was established by using conductivity and pH as input vectors and corrosion rate as output vector, and the model was utilized to predict the corrosion rate of refinery wastewater reused as circulating cooling water. The results indicate that the established prediction model with three-layer structure has the higher forecast accuracy to the corrosion rate of circulating water. So application of the artificial neural network in corrosion rate prediction of circulating cooling water is feasible, and also suggested that it has extensive practicability.
