When the filtration resistance gradually increases due to the trapped turbidity and the amount of treated water decreases, the filtration chambers II and II'
In the second case, backwashing must be carried out without stopping the introduction of waste water and the catalytic oxidation treatment.
In this backwashing, the two filtration chambers II and II' are not backwashed at the same time, but the filtration process is continued in one filtration chamber, and only the other filtration chamber is backwashed.

排水流出管１４の位置が連通口１１より上方にあるため
接触酸化室Ｉから連通路ＩＩＩへ流れることもない。At this time, since the communication port 11 is provided with a check valve 12, the backwash wastewater does not flow from the communication path III to the contact oxidation chamber (2), and conversely, the sewage that has been subjected to the contact oxidation treatment is transferred to the backwash wastewater outflow pipe 14. Since the position is above the communication port 11, there is no flow from the catalytic oxidation chamber I to the communication path III.
