The first connecting ring 351 facilitates the first connecting wire rope 35 to be connected to the primary supporting net basket 42.

[0036] Working principle: When it is necessary to pre-treat the sewage, the staff will first open the sewage inlet valve 6 to allow the external sewage to flow into the left side of the treatment tank 1 through the sewage outlet pipe 5. At this time, the partition 8 will block the sewage. Only when the sewage level rises to a level higher than the upper end of the partition 8 can the upper sewage flow to the right side of the treatment tank 1. In this process, most of the large particles of insoluble matter in the sewage will settle on the left side of the treatment tank 1 to pre-precipitate the sewage. The sewage flowing to the right side of the treatment tank 1 will first enter the primary filter layer 41 inside the first-level support basket 42. At this time, the primary filter layer 41 made of lightweight stone will filter the sewage passing through once, and the sewage after the primary filtration will continue to flow downward and enter the secondary filter layer 43 inside the secondary support basket 44. At this time The secondary filter layer made of activated carbon for water treatment will perform secondary filtration on the sewage passing through, and then the sewage after the secondary filtration will continue to flow downward and enter the tertiary filtration layer 45 inside the tertiary support basket 46. At this time, the tertiary filtration layer made of porcelain sand filter material will perform tertiary filtration on the sewage passing through, so as to pre-filter the sewage. At the same time, opening the discharge valve 7 can discharge the sewage after the tertiary filtration to avoid the filtered sewage from accumulating on the right side of the treatment tank 1, and the bottom limiting support block 47 will support the tertiary support basket 46, and the support plate 36 will respectively provide auxiliary support to the primary support basket 42 and the secondary support basket 44 to avoid contact between the primary support basket 42, the secondary support basket 44 and the tertiary support basket 46 during use.

[0037] In the later use process, when it is necessary to clean and replace the primary filter layer 41, the secondary filter layer 43 and the tertiary filter layer 45 respectively, the staff first closes the sewage inlet valve 6, and then controls the electric hoist 31 to do the winding action, so that the hoisting wire rope 32 pulls the connecting hook 33, and the connecting hook 33 pulls the first connecting wire rope 35 through the connecting ring seat 34, and then the first connecting wire rope 35 pulls the primary supporting net basket 42 through the first connecting ring 351. After the primary support basket 42 is lifted to a certain distance, the secondary support basket 44 is lifted by the second connecting wire rope 37 and the second connecting ring 371 on the upper side. After the secondary support basket 44 is lifted to a certain distance, the secondary support basket 44 is lifted by the second connecting wire rope 37 and the second connecting ring 371 on the lower side to the tertiary support basket 46, thereby respectively lifting the primary support basket 42, the secondary support basket 44 and the tertiary support basket 46 out of the treatment tank 1 (refer to Figure 4), so that it is convenient for the staff to clean and replace the primary filter layer 41, the secondary filter layer 43 and the tertiary filter layer 45 in turn. After the replacement is completed, it is only necessary to control the electric hoist 31 to release the rope, and the primary support basket 42, the secondary support basket 44 and the tertiary support basket 46 can be placed in the treatment tank 1 in situ for use.
