[0050] The working principle and use process of the present invention are as follows: when in use, the fecal sewage enters the interior of the heating tank 43, and the heating tank 43 cooperates with the heating rod 44 to start heating. The heating rod 44 heats up and absorbs heat from the fecal sewage, and the temperature rises. When the boiling point is reached, the water begins to evaporate. As the water evaporates, water vapor escapes from the sewage and is discharged through the vent pipe 6. Since the density of water vapor is smaller than that of liquid water, it will naturally move upward, while the solutes in the fecal sewage, such as salts, heavy metals, and organic matter, remain in the remaining liquid, thereby achieving the separation of water and solutes in the sewage. The organic mixture then flows into the interior of the tank body 33 through the butterfly valve 42 and the return pipe 41. The liquid mixture inside the tank body 33 cooperates with the filter element 34 for primary treatment to remove mud and sand, residual fecal particles, etc. in the fecal sewage. When the fecal sewage passes through the filter element 34, the solid particles are trapped in the filter element. 34, and the liquid part enters the flange 32 and the connecting pipe 31 through the filter element. Finally, the connecting pipe 31 guides the fecal sewage into the sewage tank 1 and starts the motor 201 synchronously. The motor 201 drives the transmission rod 204 to rotate clockwise. The transmission rod 204 rotates to drive the small toothed disc 205 to rotate. The small toothed disc 205 rotates to drive the gear 210 to rotate. The gear 210 rotates to drive the large gear ring 209 to rotate counterclockwise. The large gear ring 209 rotates to drive the slide bar 208 to rotate. The slide bar 208 rotates inside the ring 207 in coordination with the annular groove 5. When the slide bar 208 rotates, it drives the stirring rod 211 and the rectangular plate 7 to rotate synchronously. The rectangular plate 7 rotates to stir and mix the fecal sewage, so that the microorganisms are fully in contact with the excrement, the degradation efficiency is improved, and the multi-stage treatment of evaporation, filtration and stirring is realized.

[0051] To sum up: the public toilet feces and sewage treatment equipment and method, through the sewage pool 1, the stirring mechanism 2, the motor 201, the support plate 202, the partition 203, the transmission rod 204, the small gear plate 205, the support rod 206, the ring 207, the slide bar 208, the large gear ring 209, the gear 210, the stirring rod 211, the ultrafiltration mechanism 3, the connecting pipe 31, the flange 32, the tank body 33, the filter element 34 and the evaporation mechanism 4, solves the problem of low treatment efficiency of the existing septic tank and the inability to quickly treat feces and sewage in multiple stages.
