摘　　要：利用以水玻璃、硫酸、硫酸铝和废铁屑为原料研制出的聚硅酸硫酸铝铁类混凝剂 (PSAFCS) ,结合臭氧氧化预处理某垃圾填埋场渗滤液。实验结果表明 ,经过该处理工艺 ,垃圾渗滤液CODCr去除率达 70 .6% ,BOD5去除率达 75 .4% ,色度去除率为 94% 。This paper presents a new method for pre treating landfill leachate. The method is developed on the basis of bench scale experiments, in which a combined process of coagulation followed by ozone oxidation is conducted. The experiments show that average removals of more than 70% are obtained both for COD cr and BOD 5 , and 94% for colority.
