Novel sewage disposal plant for shale gas flow-back fluid

The utility model discloses a novel sewage disposal plant for shale gas flow-back fluid. The novel sewage disposal plant comprises a fluid pumping pipe, a first fluid pumping pump, a shaft, a fluid pouring pipe, a sand and stone filter, a first conveying pipe, a first fluid pumping pipe, a first fluid pumping pump, a petroleum separator, a second conveying pipe and a sewage processor, wherein the shaft is arranged on the novel sewage disposal plant for shale gas flow-back fluid and is capable of precipitating sand and big stones; the sand and stone filter is further arranged, thus filtering efficiency can be improved and sand and stone can be classified to facilitate later use; petroleum, water and sludge can be separated through the petroleum separator, thus petroleum separating effect is improved; final residual sewage can be processed at multiple stages through the sewage processor, thus processing effect is good and processing speed is fast; moreover, processed sewage not only can be used for irrigation, but also can be used for recycled.
