In the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0026] In a preferred embodiment:

[0027] like Figure 1 As shown:

[0028] This embodiment provides a clean sewage treatment mud discharge device, comprising a floating filter area 1, a diversion filter area 2, and a mud discharge filter area 3, wherein:

[0029] The floating filter area 1 is connected to the top of the diversion filter area 2; the mud discharge filter area 3 is connected to the bottom of the diversion filter area 2;

[0030] A sewage inlet pipe 4 is connected to one side of the diversion filter area 2; a water outlet pipe 5 is connected to the upper part of the floating filter area 1; a mud bucket 6 is connected to the upper part of the mud filter area 3; and a return pipe 7 is connected to the lower part of the mud filter area 3.

[0031] Furthermore, in the present embodiment, the diversion filter area 2 includes an inclined filter plate 201 and a gate plate 202; the number of the inclined filter plates 201 is multiple, and the multiple inclined filter plates 201 are arranged in parallel, so that the mud entering from the sewage inlet pipe 4 falls and the clean water rises; the gate plate 202 is arranged below the inclined filter plate 201; the gate plate 202 is set to open and close according to pressure or time conditions; the edge of the gate plate 202 is sealed with the pool wall of the diversion filter area 2 by a rubber strip, and when the gate plate 202 is closed, the sewage will not be able to fall into the mud discharge filter area 3.

[0032] Furthermore, in this embodiment, the mud discharge filtration area 3 includes a conveying roller 301 and a conveying belt 302; the conveying belt 302 is stretched and sleeved on the conveying roller 301; the conveying belt 302 is provided with filtering holes, which can separate the mud residue in the sewage and lift the mud residue to the mud bucket 6.

[0033] Furthermore, in this embodiment, a scraper 303 is also included; the scraper 303 is arranged at the lower part of the mud discharge filter area 3, and can scrape off the mud residue on the conveyor belt 302 to avoid clogging of the filter holes.

[0035] The working principle of the clean sewage treatment mud discharge device provided in this embodiment is:

[0036] The muddy sewage enters the diversion filter area 2 from the sewage inlet pipe 4. After the sewage is initially filtered, the clear liquid floats up and enters the floating filter area 1, and is filtered again through the filter filler 103, and finally discharged from the outlet pipe 5; the mud blocks accumulate on the gate 202. When the gate 202 reaches the set time or the set pressure, the gate 202 opens, and the mud blocks fall onto the conveyor belt 303 of the mud discharge filter area 3. Driven by the conveying roller 301, the mud blocks are lifted and transported to the mud bucket 6. The mud and water pass through the conveyor belt 303 and fall into the bottom of the mud discharge filter area 3. The mud pump 8 draws it back to the sewage inlet pipe 4 through the reflux pipe 7 to filter the mud again.
