[0002] The regulating tank is a pool used to regulate the flow of sewage in and out. The regulating tank plays a role in evenly distributing water volume, mixing wastewater from different times or sources, making the outflowing water quality more uniform, avoiding excessive impact loads on the treatment structures, removing some suspended matter and organic matter, reducing the load on subsequent treatment equipment, and improving the efficiency and stability of the treatment system.
