Disclosed are a composite flocculant for removing phosphorus and turbidity of waste water, and a preparation method therefor. The composite flocculant is a composite flocculant which is made by mixing and curing a natural polymer flocculant and an inorganic salt coagulant. The composite flocculant is added directly to treat phosphorus-containing waste water. Under the condition that a water quality standard requirement of a total phosphorus content (TP<0.3 mg/L) in IV-type surface water is achieved, using the composite flocculant can reduce the SS value of an effluent to 10 mg/L or less, whereas using the inorganic salt coagulant alone cannot achieve such a goal, thus the composite flocculant ensures that the effluent meets the national sewage discharge standards.
