[0032] A second water outlet 131 is provided on the upper portion of the right side wall of the primary sedimentation area 13 , and the primary sedimentation area 13 is connected to the water outlet area 14 through the second water outlet 131 .

[0033] like Figure 4 As shown, limiting grooves 132 are symmetrically provided on two opposite side walls of the primary precipitation area 13 .

[0034] like Figure 4-5 As shown, the swash plate device 2 includes a swash plate 21 , a rotating portion 22 , a driving assembly 23 and a fixing member 24 .

[0035] The slanted plate 21 includes a first slanted plate 211 and a second slanted plate 212 .

[0036] The rotating part 22 is arranged on the bottom surface of the inclined plate 21, and the rotating part 22 includes a first rotating part 221, a second rotating part 222 and a limiting protrusion 223.

[0042] The working process of the electrocatalytic oxidation sewage treatment equipment 1 with a rotatable inclined plate of the present invention is described below with reference to the accompanying drawings:

[0043] When sewage treatment equipment 1 is in operation, anode 1211 is connected to the positive pole of a power supply, and cathode 122 is connected to the negative pole of a power supply. Sewage enters reaction zone 12 through main water inlet pipe 11, undergoes an electrocatalytic oxidation reaction, and produces a large amount of suspended matter.

The water, carrying a large amount of suspended matter, flows from first outlet 123 through inclined plate assembly 2 in primary sedimentation zone 13 to second outlet 131, and finally flows out of main outlet pipe 16 on the side of outlet zone 14. When sewage treatment equipment 1 is operating normally, inclined plate assembly 2's bidirectional cylinder 231 is in a shortened state.

[0045] After the cleaning is completed, the pneumatic valve 233 is closed, and the bidirectional cylinder 231 is shortened, pulling the first inclined plate 211 and the second inclined plate 212 to an inclined state.

[0046] Therefore, the electrocatalytic oxidation sewage treatment equipment 1 with a rotatable inclined plate of the present invention has at least the following beneficial effects:

[0047] The utility model provides an electrocatalytic oxidation sewage treatment device 1 with a rotatable inclined plate, which can be used for treating sewage with high COD concentration by electrocatalytic oxidation.

[0048] When a large amount of sludge is attached to the rotatable inclined plate device 2, the pneumatic valve 233 is started to control the rotation of the inclined plate 21, eliminating the need for manual handling of the inclined plate 21, thereby facilitating operation, cleaning, and observation of the conditions in the tank.
