Therefore, reasonable and saving water has become an important issue in the development of industrial production. The fundamental reason is that the circulation of water exceeds the natural nature of water. In order to solve this problem, the only way to solve this problem is to understand the natural movement law of water, use water resources rationally, and then maintain a good water environment in the plant area. This requires the sustainable utilization of water resources in the plant area. We moved from a one-way open water model to a feedback loop process.

The circulating water and sewage treatment system is activated and starts to send sewage pumping signals and pretreatment signals to the regulating tank, and the circulating water is stirred and clarified. module, after the pretreatment, the circulating water and sewage treatment system sends the water inlet stirring signal to the stirring tank, and the treated water enters the water outlet pipe to transmit the circulating signal. The water level detection function is used to control the addition time of the liquid medicine, so as to ensure the sufficient addition of the liquid medicine in the sewage pretreatment process, and avoid the waste of excess liquid medicine. In addition, through the sensing of the water pressure inside the pipeline After the stirring and clarification process is completed, the quantitative circulation and reprocessing process of the water discharged from the stirring tank can be achieved through sensor control, which improves the processing efficiency in the stirring and clarification process.
