The invention relates to the technical field of wastewater treatment, and discloses a wastewater treatment process for organophosphorus production, which comprises the following steps: pumping wastewater of organophosphorus production into a reaction tank, adding a flocculant into a water body in the tank, and reacting in a flocculation sedimentation tank for 2-3 hours, pollutants in a water body are gathered into flower-shaped flocculent bodies under the effects of adsorption bridging, net capturing and compression of double electric layers by using a flocculating agent. According to the method, impurities in the organophosphorus wastewater are effectively removed, pollutants in the wastewater are reduced, phosphorus in the wastewater is recycled to prepare a phosphate fertilizer, the phosphorus removal effect is good, discharge of the phosphorus-containing wastewater is reduced, the recovery rate of the phosphorus element is increased, resource cyclic utilization of the phosphorus element is achieved, and t
