摘　　要：针对某市低温低浊水的特点,通过中试对比研究了高锰酸钾复合剂(PPC)、O_3、PPC与O_3联用、PPC与Cl_2联用等预氧化工艺在除浊、除有机物等方面的效能,为低温低浊水的处理提供了技术依据,结果表明:各预氧化工艺对浊度和有机物的去除均有明显的强化作用,不同预氧化工艺之间除浊效能差别不大,均在97%以上;O_3对有机物的去除率最佳,PPC与Cl_2联合预氧化次之。O_3预氧化投资较大,可选用效果略差的PPC与Cl2联合预氧化。Comparison studies on the performance of PPC(potassium permanganate composite),O_3,combination of PPC and O_3,combination of PPC and Cl_2 were completed for the removal of turbidity and organic matter on the basis of pilot experiments.The result shows that these preoxidation processes have significant effect on the removal of turbidity and organic matter,the removal rates are all above 97% with neglectable difference among different preoxidation processes.O_3 results in the highest removal rate for organic matter,combination of PPC and Cl_2 comes second.As relatively large investment is needed for O_3 preoxidation,PPC and Cl_2 are more economical.This study provides technical data for the treatment of water with low temperature and low turbidity.
