| 摘 要： | 通过试验探讨了颗粒活性炭(GAC)-石英砂生物过滤对湘江微污染源水的处理特性.结果表明,生物过滤具有良好的去浊特性,浊度的去除是传统吸附截留和生物吸附共同作用的结果;生物过滤可有效去除微污染源水中的有机物、NH4+-N、Fe和Mn,提高饮用水生物稳定性;生物过滤对于分子量小于1000和分子量在3000～6000之间的有机物有较好的去除效果.

| Abstract: | The character of treating Xiangjiang River micro-polluted source water with granular activated carbon (GAC) sand biofiltration was investigated with test. The biofiltration possessed superior character on turbidity removal, which was the result of the combined action of traditional adsorption catching and biosorption. It could efficiently remove the organic matter NH4 -N, Fe and Mn in the micro-polluted source water to enhance the biological stability of drinking water; and the fairly good removal effect of organic matter of molecular weight<1000 and between 3000~6000. |
