两种活性炭滤池深度处理饮用水的研究

通过新鲜活性炭滤池和生物活性炭滤池对黄河水经常规处理出水中有机物和消毒副产物的对比试验研究发现，在相同的水力停留时间下，两种炭滤池对水中CODMn、UV254、三氯甲烷生成势、一溴二氯甲烷生成势都有明显的去除效果，但前者对这些有机物的去除效果更为显著；活性炭上生物膜的发育成熟过程对CODMn、三氯甲烷生成势、一溴二氯甲烷生成势的影响不明显；生物活性炭滤池不能有效去除二溴一氯甲烷生成势，反而引起出水中二溴一氯甲烷生成势的升高；新鲜活性炭滤池对二溴一氯甲烷生成势的去除效果没有明显规律性．

Study on Advanced Treatment of the Drinking Water Using Two Activated Carbon Filters

Through comparison test between the organic matters and the by-products of disinfection in water yielded by means of con- ventional treatment for the Yellow River water in the fresh activated carbon filter and biological activated carbon filter, it is found that under the same hydraulic retention time, the CODM., UV254 , the generation potential of chloroform and bromodi- chloromethane are eliminated remarkably in the both filters ; however, the elimination effect of the former is more remarka- ble. The growth and maturation process of the biomembrane have no obvious effect on the CODM., and the generation poten- tial of chloroform and bromodichloromethane. Instead of effectively eliminating the generation potential of chlorodibro- momethane in water, the biological activated carbon filter arouses the rising of it. The elimination effect of fresh activated carbon filter on the generation potential of chlorodibromomethane has no obvious regularity to track.
