• Landfill leachate reverse osmosis concentrated water (RO concentrated water) is a kind of wastewater with high organic matter concentration, chemical oxygen demand (COD), turbidity, and chroma. The RO concentrated water is pretreated using coagulation method; then the coagulation effect of FeCl3, Fe2(SO4)3, Fe(NO3)3 and PAC on the leachate RO concentrated water is investigated in the experiment. The result shows that FeCl3 is the best coagulant. The removal rate of total organic compounds (TOC) reaches the highest (92.23%) under the condition of 8.0 g/L FeCl3 dosage, pH=6, 3 mg/L PAM, and 150 r/min rotation speed, and the removal rate of COD, NH3-N, and chroma are 73.91%, 28.3%, and 79%, respectively.
