Rapid treatment method for fracturing flowback fluid

The invention discloses a rapid treatment method for a fracturing flowback fluid. The rapid treatment method comprises: (1) pumping a fracturing flowback fluid into an electron beam irradiation chamber, and staying for 20-120 s in the electron beam irradiation chamber; (2) adding a coagulant and a flocculant into the sewage treated by the electron beam irradiation chamber, and clarifying in a flocculation precipitation pool; (3) feeding the water treated by the flocculation precipitation a precision filtration pool, and carrying out fine filtration; and (4) collecting the water filtered by theprecision filtration pool in a clear water pool. According to the present invention, the gel breaking stage uses physical gel breaking so as to achieve clean gel breaking and greatly reduce the sideeffects of external agents, such that the reuse quality of the fracturing flowback fluid is good, and the fracturing flowback fluid is safe; the gel breaking time is shortened from 5-120 min to 20-120s so as to greatly improve the gel breaking speed; and compared with the traditional chemical gel breaking method and the biological gel breaking method, the method of the present invention simplifyfeeding equipment and other supporting equipment, reduces the occupation area, and reduces the complexity of manual operation.
