| Abstract: | The landfill leachate was treated by the coagulation sedimentation with polyaluminium chloride(PAC),polyferric sulfate(PFS) and poly aluminum ferric chloride(PAFC) added respectively.The effects of the said three kinds of coagulants on TOC,CODCr and UV254 removal were investigated;furthermore,the best coagulant and the optimal coagulant dosage were determined as PAC and 6 g/L respectively according to the single factor experiment.The method of humus separation was simplified,and the content of humic acids(HA) and fulvic acids(FA) in the water which had been coagulated by the said three kinds of coagulants were examed at the same time.The results showed that: the performance of PAC for HA removal was the best,while the efficiency of PFS for FA removal was slightly higher than that of the other two coagulants. |
