The utility model discloses oil and gas well fracturing flow-back fluid treatment equipment. Fracturing flow-back fluid is lifted by a flow-back fluid lifting pump and sequentially passes through a pipeline filter, a pipeline mixer set, a micro-vortex flocculator and a filtering unit to reach a clean water tank and a plate-and-frame filter press. Pressure sensors are mounted at an inlet and an outlet of the micro-vortex flocculator; when the system pressure exceeds a set differential pressure protection value; when the filtering unit is blocked, the operation of the filtering pump can be stopped in time, whether the equipment is blocked or not can be found, an operator can conveniently clean the equipment in time and find that the treatment capacity of the equipment is reduced due to blockage, and the technical problem that the equipment is damaged due to overhigh pressure when a filtering material of the filtering unit is seriously polluted can be effectively solved. And the filteringunit is formed by connec
