摘　　要： 采用磁种-磁滤技术处理广州市两条河涌的污染水,考察了磁种投加量、混凝剂用量、磁场强度和磁滤速度对出水浊度的影响,并确定了最佳试验条件。结果表明,该工艺对TP、SS和浊度的去除效果较好,去除率分别为96 2%、92 4%和93 9%,对CODCr有一定的去除效果,去除率为68 2%,但对NH+4 N的去除效果较差,去除率仅为25%。 Treatment of water from polluted rivers in Guangzhou was studied by means of magnetic seed-magnetic filtration. Effects of (magnetic) seed dosage,coagulant dosage, magnetic field intensity and filtering velocity on the turbidity of effluent were investigated,and the optimal trial conditions were confirmed. The result indicated that removal efficiencies of TP, SS and turbidity were excellent, the removal rates were 96.2%,92.4% and 93.9% respectively, COD_(Cr) could be removed to some extent with removal rate of 68.2%, and the (removal) efficiency of NH^+_4-N was low with removal rate of 25%.
