Method for recycling injection polymers by polymer-containing sewage advanced treatment

The invention relates to a method for recycling injection polymers by polymer-containing sewage advanced treatment. On the basis of the water quality characteristics of the polymer-containing sewage and the polymer-containing sewage high-efficiency advanced treatment technique, the polymer-containing sewage can be recycled for injection polymers without lowering the viscosity of the polymer solution, thereby solving the problem of low viscosity of sewage injection polymers.
