【摘要】 介绍了生物活性炭滤池 (BACF)对微污染水源预处理的机理 ,考察了生物活性炭滤池不同深度污染基质的分布 .实验表明 ,滤池对各项污染指标有很好的去除效果 ,对水中COD、氨氮、浊度和UV2 54的去除率分别为 2 3.9% ,75 .3% ,2 9.4%和 2 0 .3% .通过研究滤池沿程去除效果的分布 ,确定了污染物去除的主要区域更多还原

【Abstract】 The principle and mechanics of biological activated carbon filter(BACF)used in pre purifying micro polluted surface water are introduced, and the distribution of main index pollutants at different depths of BACF is researched.The experimental result shows that the filter has a satisfactory treatment effect to the removal of main index pollutants. The removal rate of COD Cr ,NH 4 N, turbidity and UV 254 is 23.9%,75.3%,29.4% and 20.3% respectively. The main areas of removing pollutants are defined according to the distribution of removal effect along the filter.更多还原
