针对垃圾渗滤液经生化处理后出水CODCr和色度偏高,可生化性差（BOD5/CODCr≤0.1）的特点,为进一步去除CODCr,降低色度,采用PAC和PFS两种混凝剂对出水进行处理,并对两者的混凝效果进行比较。试验表明,PFS最佳投加量为0.7 mL.L-1,CODCr去除率达到74.3%,色度去除率88.6%;PAC最佳投加量为1 g.L-1,去除率达到51.9%,色度去除率达到77.8%。无论从CODCr或色度的去除率来看,PFS的混凝效果均优于PAC。

For CODCr and chroma were still high,together with bad biochemical characters（BOD5/CODCr≤0.1）,the leachate effluent was treated with coagulants of poly aluminum chloride（PAC） and Polyferric Sulfate Composite Flocculant（PFS） in order to further removal CODCr and chroma,corresponding to their coagulating effect being compared.It had been demonstrated that the optimally adding amount of PFS was 0.7 mL？L-1,corresponding to removal efficiencies of CODCr and chroma being 74.3 % and 88.6 %,respectively.The optimally adding amount of PAC was 1 g？L-1,corresponding to removal efficiencies of CODCr and chroma being 51.9 % and 77.8 %,respectively.It had been indicated that the coagulating efficiencies of CODCr and chroma of PFS was superior to that of PAC.
