Phosphorus ore mine inflow treatment system and method

The invention discloses a phosphorus ore mine inflow treatment system and a usage method and aims at mainly solving the problem that at present, phosphorus ore mine inflow is high in phosphorus content, unstable in water quality phosphorus concentration and high in treatment cost. The treatment system comprises a primary settling pond, a primary online total-phosphorus detector, a secondary settling pond, a phosphorous removal pond, an aging pond, a secondary online total-phosphorus detector and a qualified discharge pre-storage pond which are sequentially communicated. The primary online total-phosphorus detector is provided with an qualified water outlet, the qualified water outlet is communicated with the qualified discharge pre-storage pond, the secondary online total-phosphorus detector is provided with a non-qualified water outlet, and the non-qualified water outlet is communicated with the secondary settling pond. The phosphorus ore mine inflow treatment system treats the phosphorus ore mine inflow and
