Applied research on wastewater treatment based on least squares support vector machine

In view of lots of problems such as the time-delay caused by wastewater indices off-line analysis and a long sampling interval in industrial manufacturing process, a sewage treatment soft measurement method based on least squares support vector machine is proposed in this paper. The simulation results show that the method in this paper is feasible and has a lot of merits such as high precision, fast speed, lower secondary pollution, etc, and this method also supply a theoretical guidance for realization in real-time on-line examination of the sewage.
