PASSC絮凝剂处理垃圾渗滤液的试验研究

Study on the Treatment of Leach Liquor Using PASSC Coagulant

采用交变脉冲电解合成的聚合氯化硅酸硫酸铝絮凝剂，对武汉市某垃圾填埋场的垃圾渗滤液进行了初步絮凝处理．结果表明：当被处理的渗滤液pH值在3．5～8，聚合氯化硅酸硫铝絮凝剂的投加量为1．5×10^-5mol·l^-1时，其COD、NH4^＋-N和色度的去除率分别为66％、30％和66．27％．明显的高于AlCl3和Al2（SO4）3的处理效果，与PAM和市售聚合氯化铝处理效果相当．

This paper deals with the treatment of the leach liquor of Wuhan City x Landfill Space of Refuse using poly-aluminum silicate sulfate chloride （APSSC） synthesized by changeable frequency alternating current pulse electrolysis equipment. It shows that the removal of COD,NH＋-N and color of leach liquor can reach 66%, 30% and 66. 27% respectively when the pH value of leach liquor is from 3.5 to 8.0 and the dose of PASSC is CAl = 1. 5 × 10^-5 mol/L.
