The existing process for sewage treatment in decentralized regions is mainly a biological method, and although the method has high treatment efficiency, low cost and simple and feasible technology, relatively small water fluctuation needs to be ensured.
Although the discharge water volume of sewage in a decentralized area is small, the sewage volume is influenced by factors such as water consumption habits of people, holidays, seasons and the like, the water volume change is obvious, and the fluctuation of the water volume brings great challenges to the stable operation of sewage treatment equipment.
Compared with an intermittent water inlet operation mode, continuous water inlet has certain advantages for maintaining the water temperature required by subsequent biochemical treatment, reducing pollution load fluctuation and ensuring high efficiency and stability of equipment operation.
Most of the existing sewage treatment in the decentralized region adopts an adjusting tank and an internal water inlet pump as equipment for coping with water quantity fluctuation.
