| 摘 要： | 采用超滤膜法对太湖源水中的蓝藻腐败产物进行了分子质量分级,研究了混凝、超滤、臭氧氧化及活性炭吸附等工艺对腐败产物的去除效果.结果表明,以CODMn表征的有机物主要分布在分子质量>40 ku和<10 ku的区间,致嗅物质主要集中在10-40 ku的区间,以UV254表征的有机物主要分布在分子质量<40 ku的区间.混凝、超滤特别适于去除分子质量较大的有机物,对致嗅有机物的去除效果不明显;臭氧氧化能显著去除致嗅有机物,同时还将大分子有机物氧化为小分子有机物;活性炭对小分子有机物的吸附效果明显,能够有效去除分子质量<10 ku的有机物.将这四种工艺进行组合能充分发挥各自的作用,保障饮用水的安全性.

| Abstract: | Molecular weight(MW) distribution of the putrefactive products of algae in source water from Taihu Lake was determined by UF membrane method.The removal efficiencies of the putrefactive products by coagulation,ultrafiltration,ozonation and activated carbon adsorption processes were investigated.The results show that the majority of organic substances characterized by CODMn have MWs higher than 40 ku or lower than 10 ku,while the odorous compounds have MWs of 10 to 40 ku and the organic substances characteri... |
