摘要
实验研究了絮凝剂聚铝(PAC)与阳离子高分子絮凝剂(PDMDAAC)联合处理生活污水的效果。结果表明:聚铝与阳离子联用比单独用聚铝处理生活污水效果更好;聚铝+阳离子对生活污水CODCr具有良好的去除能力;当投加20mg/L的聚铝+0.4mg/L的阳离子,调节水体pH=8.5时,处理效果最理想,CODCr去除率可达77%以上。
This paper studies the effect of aluminum sulfate （PAC） flocculating agent combined with ployacrylamide （PDMDAAC） co-flocculent on the treatment of domestic sewage. The results indicate that the effect of PAC combined with PDMDAAC is better for the treatment of domestic sewage than that of a single PAC, and PAC＋PDMDAAC can significantly remove CODc, When 20 mg/L PAC and 0.4 mg/L PDMDAAC are added, and pH is controlled at 8.5, the resuh is the most satisfactory. CODcr removal is more than 77%.
