The refractory landfill leach ate has characteristics about complicated composition and high content pollutants of micro-nanometer particles. At present it was treated by biochemical process, but it was difficult to meet the effluent water discharge standards and recycling because of difficult degradable organic matter. A new inorganic polymer flocculant---poly-silicate zinc ferric sulfate with boric acid radical, named PFZSSB, was developed. And it was especially suitable for removal of micro-nanometer particles of organic pollutants. The study focused on removing these pollutants in landfill leachate advanced treatment. The results illustrated that the treatment effect of PFZSSB was suitable, and the removal rate of NH3-N, COD and turbidity were up to 13.68%, 51.09% and 59.09% respectively. This disposing process was highly efficient, simple and the cost was reduced greatly.
