Efficient treatment process for landfill leachate

The invention relates to the technical field of landfill leachate treatment, in particular to an efficient treatment process for landfill leachate. The process comprises the following steps of crushing and disinfecting a landfill raw material; compressing the landfill raw material to enable leachate in the landfill raw material to seep out; carrying out preliminary flocculation deposition on the landfill leachate; separating metal ions in the landfill leachate; and filtering macromolecular substances in the landfill leachate. The efficient treatment process has the beneficial effects that through crushing and disinfection, the volume of the landfill raw material is reduced, meanwhile, bacteria and microorganisms in the landfill raw material are reduced, the leachate in the landfill raw material rapidly seeps out through compression, flocculation deposition is conducted on the landfill leachate through a modified flocculant, tiny suspended matters in the landfill leachate are wrapped through the modified flocc
