Wastewater phosphorus removal process

The invention provides a wastewater dephosphorization process which is characterized by comprising the following steps: step 1, feeding wastewater to an oxidation unit for oxidation to obtain wastewater A; 2, feeding the wastewater A to a coagulation unit, adding a coagulant, and stirring to obtain wastewater B; 3, feeding the wastewater B to a flocculation unit, and adding a flocculant to obtain wastewater C; 4, feeding the wastewater C to a precipitation unit, and separating to obtain sludge and wastewater D; and 5, feeding the wastewater D to a filtering unit, and filtering to obtain dephosphorized water. The step of oxidizing the wastewater is set at the front end of the whole process, so that the concentration of organic phosphorus in the wastewater is effectively reduced, the dosage of a coagulant (phosphorus removal agent) in a subsequent unit is reduced, the phosphorus removal effect of the subsequent unit is ensured, the use of the phosphorus removal agent is reduced, the cost is saved, and the gener
