When the sewage treatment inside the tank body 1 is completed, the operator can discharge the relatively clear grey water to the external space through the first water outlet pipe 21. After the relatively clear grey water is discharged, the sewage sediment and the grey water mixed with the sediment remain inside the tank body 1. At this time, the operator opens the water outlet valve 26, and the remaining sewage sediment and the grey water mixed with the sediment in the tank body 1 pass through the collecting pipe 24. The collecting pipe 24 can collect the sewage sediment, and then the grey water separated from the sewage sediment is discharged to the external space through the second water outlet pipe 22.

When the operator needs to replace the filter layer 27 in the collection pipe 24 , the collection pipe 24 can be removed from the second water outlet pipe 22 by dismantling the connection between the lower flange 25 and the upper flange 23 , and then the operator can replace the filter layer 27 in the collection pipe 24 .
