| 摘 要： | 以微污染湖水为原水,考察了聚合氯化铝(PAC)单独投加以及与高锰酸盐复合药剂(PPC)联合投加时原水经混凝沉淀后的除污效果。结果表明,PAC与PPC联合投加能有效降低沉后水的色度、浊度、有机物含量和藻类数等;当投加0.4～0.6 mg/L的PPC反应10 min后,再投加20～30 mg/L的PAC,可获得良好的沉淀效果,对色度、浊度、UV254、CODMn和藻类的平均去除率分别可达到50%、80%、25%、26%和78%;与单独投加PAC相比,投加PPC后再投加PAC可减少一半以上的PAC投加量,生产成本大大降低。

| Abstract: | Taking micro-polluted lake water as raw water,the pollutant removal efficiency of coagulation and sedimentation process was investigated when using single addition of PAC and combined addition of PAC and PPC.The results demonstrated that the combined addition of PAC and PPC could effectively reduce color,turbidity,organic matter and algae in the sedimentation effluent.When 0.4 to 0.6 mg/L of PPC was added,and 20 to 30 mg/L of PAC was added after 10 min reaction,good coagulation and sedimentation effect could be achieved.The average removal rates of color,turbidity,UV254,CODMn and algae were 50%,80%,25%,26% and 78%,respectively.Compared to the single addition of PAC,adding PPC before adding PAC saves more than 50% of PAC dosage and lowers production costs. |
