Construction of Industrial Sewage Early Warning System Based on Bayesian Algorithm and Artificial Neural Network

Abstract

In the process of industrialization, water pollution accidents occur from time to time, resulting in major economic losses and negative impacts on the water environment. Statistical analysis shows that it is difficult to issue early warning quickly and effectively before the accident, leading to unavoidable water pollution accidents. In order to improve the environment and reduce water pollution accidents, governments and enterprises at all levels need to invest a lot of human resources. In this paper, Bayesian algorithm and artificial neural network are used to study industrial wastewater early warning and effectively prevent water pollution accidents. This paper first introduces the main parts and functions of industrial sewage early warning, then uses Bayesian network to carry out water quality early warning, introduces the calculation process of Bayesian water quality evaluation, and establishes Bayesian network water quality early warning system. Then this paper uses artificial neural network to carry out water quality early warning, builds a comprehensive model of neural network evaluation, and introduces the process of artificial neural network water quality evaluation in detail. In the experimental part, Bayesian algorithm and artificial neural network algorithm are used to evaluate the grade of industrial sewage. The experimental results show that the two algorithms have good accuracy, F1 value and recall rate when evaluating the quality of industrial sewage. The accuracy rate of the industrial sewage quality evaluation results of the two algorithms is more than 95%, which shows that Bayesian algorithm and artificial neural network can be well applied in the industrial sewage early warning field.
