description The treatment device comprises a waste liquid tank, a liquid pump, an oxidation-reduction reaction tank, a neutralization reaction device, a slurry pump and a rotary drum centrifugal machine, the waste liquid tank is communicated with the oxidation-reduction reaction tank through the liquid pump, and the output end of the oxidation-reduction reaction tank is communicated with a pipeline of the neutralization reaction device; the treatment device is used for carrying out multi-stage disinfection and purification treatment on waste liquid, the waste liquid is pumped into the oxidation-reduction reaction tank through the liquid pump, oxidation-reduction reaction is carried out by adding a reducing agent, pH adjustment is carried out, and after adjustment is completed, the waste liquid is pumped into the neutralization reaction device again. By adding alkali liquor and carrying out neutralization reaction, heavy metal ions in the waste liquid are automatically settled, and after settling is completed, the waste l
