The sewage enters the sewage box 33 and is discharged through the fifth pipe 34, and after being collected, the sewage is treated and discharged, and the oil remains in the separation tank 28.
After the treatment is finished, the oil in the treatment cylinder 1 and the squeezed silt are collected and treated.
