The invention relates to an in situ regeneration method for filler saturated in adsorbing phosphorus in artificial wetland, which directly adopts desolvente to process the filler which is saturated in absorbing phosphorus by in situ solubilization regeneration, so as to lead the phosphorus adsorbed on the filler to be desorbed and discharged out of the system along with the desolvente, ensure the phosphorus of the filler to have regenerated adsorption function and restore the treatment efficiency of the artificial wetland for the phosphorus. The method of the invention comprises the steps of selection and preparation of the desolvente, in situ solubilization, post treatment, etc. The simple method is adopted to solve the problem of the adsorbed and saturated phosphorus in the artificial wetland, leads to the function of the absorbing phosphorus to be regenerated without replacing the filler, does not affect the absorption of stroma for the phosphorus, and improves the processing efficiency of the artificial w
