摘　　要：通过小试和上机试验,对磁分离系统在各种药剂配比下的运行效果进行比较。结果表明,磁分离系统出水水质(主要为COD)与聚合氯化铝(PAC)的投加量关系最大,与磁粉投加量有一定关系,与聚丙烯酰胺(PAM)的投加量无明显相关性。运行成本中,PAC费用占总药剂成本的88%～89%。为提高运行的稳定性,需要对各药剂投加量进行调整,同时需要对部分设备进行改造。The operation efficiency of magnetic separation system using different dosages of chemi- cals was compared in small-scale and large-scale tests. The results showed that the influence of PAC dosage on COD removal was the greatest, of magnetic powder dosage was the second, and of PAM dosage was the smallest. The cost of PAC was 88% to 89% of the total chemicals cost. The dosage of chemicals should be compromised with reconstruction of existing equipment to improve the operation stability of the system.
