| 摘 要： | 用高锰酸盐复合药剂对太湖水除蓝藻除色度的试验结果表明，其强化混凝作用使得除蓝藻除色度的效果显著，并强化了后续过滤处理的效果．在此基础上，探讨了高锰酸盐复合药剂强化混凝的致因，认为高锰酸盐复合药剂强化混凝可有效去除蓝藻和色度，是其核心组分高锰酸钾的主体作用与复合成分在水中协同作用的共同结果，即新生态水合二氧化锰的作用、蓝藻有机胶质层与有机物涂层的破坏、杀藻灭活、难溶化合物的吸附共沉作用以及阳、阴离子对混凝过程中pH值平衡的作用等，

| Abstract: | Experimental study indicates that enhanced-coagulation with potassium permanganate composite(PPC) can effectively remove blue-green algae and chroma from the Taihu Lake,and it can also enhance the effect of later filtering process.Furthermore,the mechanism of enhanced-coagulation with PPC was discussed.It is concluded that the action of the core component of PPC and cooperative actions of its composite components in water are the main reasons for the effect of enhanced-coagulation,the factors including the function of hydration of manganese dioxide,destruction of gluey layer of blue-green algae,algae killing and activity elimination,adsorption and sediment of slightly soluble compounds,the functions of positive and negative ions in pH value balance,etc. |
