[0065] It should be noted that after filtering by feathers and feces, the remaining water structure in the sewage is deposited at the bottom of the treatment tank 1. At this time, it is filtered and protected by the filter cover 703. When the water pump 7 is started, the water inlet pipe 701 will extract the water in the treatment tank 1 and guide it to the annular pipe 704 through the drainage pipe 702. At this time, the water in the annular pipe 704 is sprayed by multiple nozzles 705 along the top of the feather filter barrel 8.

[0066] Embodiment 2, a method for treating wastewater from meat duck farming, using the treatment equipment of embodiment 1, the treatment method comprises the following steps:

[0067] The first step is to assemble the graded filtering mechanism, put the feces filtering part on the bottom of the feather filtering part, and then fix the two together;

At this time, the rotating drive mechanism is started, and the driving mechanism drives the graded filtering mechanism to rotate. At this time, the sewage first enters the feather filtering part, and the duck feathers mixed in the sewage will be filtered and retained in the feather filtering part, while the feces mixed with the sewage enters the feces processing part for further filtration, so that the feces will be reserved in the feces processing part, and the sewage flows into the treatment tank body 1. At this time, the pumping mechanism is started again, and the sewage is pumped from the top of the tank cover 2 to the feather processing part for watering, so as to ensure that the graded filtering mechanism remains unobstructed for sewage treatment.

[0073] It should be noted that the sewage entering the treatment tank body 1 through the feed pipe 3 first enters the feather filter barrel 8 for filtration, and the sewage after filtering the feathers is filtered by the feces filter barrel 9. The sewage after filtering the feces solid matter accumulates in the treatment tank body 1. At this time, in order to ensure the order of the treatment process, the pumping mechanism can be turned on to sprinkle on the feather filter barrel 8 to perform liquid flushing circulation. After the treatment is completed, the discharge pipe 101 is opened to drain the water after the filtration treatment.
