1 Introduction
With the rapid development of China’s industry, people’s material lives have increased, and the pollution of our living environment has become increasingly acute. In particular, water pollution has seriously threatened the health of human beings, and we have promoted low-carbon economy and energy conservation and emission reduction in the global trend. How to save energy and efficiently solve the problem of sewage treatment has become a hot topic of social research. In addition to the ever-increasing investment in environmental protection and the continuous deepening of reforms in the sewage treatment industry, the operation and management of urban sewage treatment plants has become market-oriented, professional, large-scale and group-oriented. Therefore, the implementation of full-scale automatic control and remote monitoring of the production and operation of the sewage treatment plant is very effective in reducing operating costs, enhancing production management, ensuring the normal and efficient operation of the sewage treatment process, meeting the standard discharge of water quality, and improving the efficiency and quality of the operation and management of the enterprise. Significance.
In the sewage treatment process, the entire system must be operated safely and reliably. The reliability of the system is the first principle to be considered in the aspects of process equipment, instruments, electrical automatic control systems, computer and network systems, system design, and software design.
