摘要

对长江原水进行了60天的贮存试验。结果表明，在贮存的前10d里水的浊度便由60NTU下降到了1NrrU，而整个贮存期间TOC仅下降了0．291mg／L。用超滤膜法和XAD树脂吸附分离法对贮存水中不同分子量区间、不同极性有机物进行分析，发现贮存水中发生降解的有机物主要是分子量小于4Kdalton的有机物，同时亲水性有机物向疏水性有机物发生了转化。

Abstract

In this paper

the untreated water from Yangtze River was stored. The turbidity of the water was reduced from 60 NTU to 1 NTU in the first 10 days

but the TOC value reduced only by 0.291 mg/L in 60 days. The organic molecular weight distribution and the organic polarity of storage water was analyzed using UF and XAD resin respectively. It was found that the organic matter

whose molecular weight is less than 4000 dalton

was decomposed and the hydrophilic organic matter was converted into hydrophobic organic matter.
