The types of pollutants contained in different types of sewage are different, and the concentration of pollutants varies greatly. When a high-pollution factory suddenly discharges a large amount of sewage to the sewage treatment plant, in order to deal with the sudden high-pollution sewage, it is necessary to add more additional to reduce the concentration of pollutants in sewage, and most high-pollution factories only discharge sewage during the day and do not discharge at night, so the corresponding sewage treatment equipment can only purify low-pollution sewage at night, reducing the treatment cost. Equipment utilization.

Therefore, it is very necessary to provide an efficient automatic regulation water distribution system for sewage.
