摘　　要：利用膜分级过滤技术对生物陶粒滤池去除天津引滦水原水中的不同分子量有机物的去除效果进行了研究分析.研究表明:生物陶粒滤池对分子量大于10 000道尔顿的有机物去除效果最好,可达到60%以上;对分子量在1 000～4 000道尔顿的有机物去除率也能达到50%以上;但对分子量＜1 000道尔顿的有机物去除率仅为10%;而分子量在4 000～10 000道尔顿的有机物在生物陶粒滤池处理过程中非但没有减少,反而有所增加.Thetechnologyof membrane-classified is usedto analysetheremoval effect ofdifferentmolecularweight organics in the Luan river, which is treated by the Bio-ceramic Filter. The result shows that the (BCF) has more than 60% removal of organics larger than molecular weight (MW) of 10 000 dalton, up to 50% removal of organics MW between 1 000- 4 000 dalton, and only 10 % of organics less than MW of 1 000 dalton, but the amount of organics MW between 4 000-10 000 dalton increases in the BCF treatment, instead of decreasing.
