[0180] Example 1
[0181] A method for advanced treatment of leachate, the liquid treatment of leachate is carried out as figure 1 The system shown is implemented.
[0182] The leachate to be treated is prepared in the leachate distribution pool 500, and then passed into the electrolytic cell 100 for electrochemical treatment; solid-liquid separation is performed on the flocculated turbid liquid after electrochemical treatment, and the flocculated suspended matter is discharged; solid-liquid separation The latter effluent is passed into the wetland purification device 200, and the leachate pollutants are degraded or removed through the laid filler layer, such as the fixation and removal of nitrogen, phosphorus and heavy metals, the degradation of refractory pollutants, and finally the effluent.
[0183] The electrolytic cell 100 consists of the anode Ti / Pt / SbO 2 -Sb 2 O 4 , Cathode graphite carbon felt and iron amphoteric electrode composition, anode 110, cathode 120 and amphoteric e...
