Aims:The aims of this paper are to design a monitoring system for wastewater disposal. Study Design: The study design is to design a monitoring system and perform simulation analysis based on Kingview software. Place and Duration of Study:The place and duration of study are North China University of Water Resources and Electric power and one month respectively. Methodology: The methodology used is computer simulation technology. Results: The result of the experiment is to monitor the sewage disposal process through the developed monitoring system. Conclusion: The conclusion is that the monitoring system can achieve dynamic control of the sewage disposal process.

This paper focuses on the design of software and hardware for the purification and recycling of domestic sewage discharged from a residential area. According to the characteristics of domestic sewage, the process used in this paper is determined to be Sequencing Batch Reactor (SBR) process and the allocation of system input/output (I/O) port. According to the determination of the process flow to select appropriate instruments, sensors and other equipment, using Programmable Logic Controller (PLC) to design the system in manual mode and automatic mode of the program respectively, to achieve the function of sewage treatment.
