The invention discloses an urban excrement purification treatment system, which comprises a box body, a material retrieving mechanism is arranged in the box body, a water outlet is arranged at the bottom of the side wall of the box body, and a retrieving mechanism is arranged on the side of the material retrieving mechanism. A pushing mechanism that matches the material mechanism, the pushing mechanism includes a first cylinder, a push plate movably connected with the first cylinder, and a second cylinder arranged on the lower surface of the push plate; the push plate can push the seepage cloth pocket upwards, Thereby, the feces in the seepage cloth pocket can be cleaned out labor-savingly, and the first cylinder is used to push the push plate, so that the push plate can upwardly lift the seepage cloth pocket, so that the feces in the seepage cloth pocket can be pushed out by the push plate, thereby To clean up the feces in the seepage cloth pocket, and the second cylinder is used to push one side of the push plate, so that the push plate can be tilted to one side. When the push plate is pushed to the top by the first cylinder, the push plate can push the seepage tilted The feces in the cloth pocket, thereby more thoroughly cleaning up the feces in the seepage cloth pocket, and enhanced the effect of cleaning the seepage excrement.
